Organization And Nature Of Business	1	Organization and Nature of Business
	On March 22, 2012, Dakota Plains Holdings, Inc., formerly known as MCT Holding Corporation ("DP" or the "Company," "our" and words of similar import), Dakota Plains, Inc., a Minnesota corporation engaged in the crude oil transportation business ("Dakota Plains"), and DP Acquisition Corporation, a Minnesota corporation ("Merger Subsidiary") entered into an Agreement and Plan of Merger (the "Merger Agreement"). Under the Merger Agreement, the Merger Subsidiary merged with and into Dakota Plains (the "Initial Merger"), the separate corporate existence of the Merger Subsidiary ceased, and Dakota Plains continued as the surviving corporation and as a wholly owned subsidiary of the Company. See Note 14 for details of the Initial Merger.
	Dakota Plains Holdings, Inc. is an integrated midstream energy company, principally focused on developing and owning transloading facilities and transloading crude oil and related products within the Williston Basin.
	Dakota Plains Transloading, LLC ("DPT"), a wholly owned subsidiary of the Company, was formed in April 2011 primarily to participate in the ownership and operation of a transloading facility near New Town, North Dakota through which producers, transporters and marketers may transload crude oil and related products from and onto the Canadian Pacific Railway.
	Dakota Plains Marketing, LLC ("DPM"), a wholly owned subsidiary of the Company, was formed in April 2011 primarily to engage in the purchase, sale, storage, transport and marketing of hydrocarbons produced within North Dakota to or from refineries and other end-users or persons. Effective November 30, 2014, the Company purchased the remaining ownership interest in DPTSM from PTS and immediately ceased the purchase and sale of crude oil.
	Dakota Plains Trucking, LLC, a wholly owned subsidiary of the Company, was formed in September 2012 primarily to engage in the transportation by road of hydrocarbons and materials used or produced in the extraction of hydrocarbons to or from refineries and other end-users or persons, wherever located. Effective November 24, 2014, the Company sold its membership interest in Dakota Plains Services, LLC ("DPS").
	Dakota Plains Sand, LLC, a wholly owned subsidiary of the Company, was formed in May 2014 primarily to participate in the ownership and operation of a sand transloading facility near New Town, North Dakota.
	The Company is governed by its board of directors and managed by its officers.

Summary Of Significant Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	2	Summary of Significant Accounting Policies
	These consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP").
	New Accounting Pronouncements
	From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board ("FASB") that are adopted by the Company as of the specified effective date. If not discussed, management believes that the impact of recently issued standards, which are not yet effective, will not have a material impact on the Company's consolidated financial statements upon adoption.
	In July 2013, the FASB issued Accounting Standards Update ("ASU") No. 2013-11 "Income Taxes – Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carry Forward, a Similar Tax Loss, or a Tax Credit Carry Forward Exists" which provides that entities should present the unrecognized tax benefit as a reduction of the deferred tax asset for a net operating loss ("NOL") or similar tax loss or tax credit carry forward rather than as a liability when the uncertain tax position would reduce the NOL or other carry forward under the tax law. The ASU is effective for annual and interim periods for fiscal years beginning on or after December 15, 2013. The Company adopted this ASU effective January 1, 2014. The adoption of this update did not have a material impact on the Company's consolidated results of operations, financial position or disclosures.
	In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers". The standard's core principle is that an entity shall recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard generally requires an entity to identify performance obligations in its contracts, estimate the amount of variable consideration to be received in the transaction price, allocate the transaction price to each separate performance obligation, and recognize revenue as obligations are satisfied. The standard will be effective for annual and interim periods beginning after December 15, 2016. The standard allows for either full retrospective adoption, meaning the standard is applied to all periods presented in the financial statements, or modified retrospective adoption, meaning the standard is applied only to the most current period presented. The Company is currently evaluating the impact of the provisions of ASU 2014-09; however, the standard is not expected to have a material effect on the Company's consolidated financial position, results of operations or cash flows.
	In April 2014, the FASB issued ASU No. 2014-8, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity". This ASU changes the requirements for reporting discontinued operations to disposals of components of an entity that represent strategic shifts that have a major effect on an entity's operations and financial results. The standard also expands the disclosures for discontinued operations and requires new disclosures related to individually material disposals that do not qualify for discontinued operations reporting. The guidance is effective for interim and annual periods beginning after December 15, 2014, and should be applied prospectively. Early adoption is permitted. The Company is currently evaluating the impact of adoption of this ASU on its consolidated financial statements.
	In June 2014, the FASB issued ASU 2014-12, "Compensation - Stock Compensation" effective for annual periods and interim periods within those periods beginning after December 15, 2015. The amendments require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. The Company is currently evaluating the impact of the provisions of ASU 2014-12, however, the standard is not expected to have a material effect on the Company's consolidated financial position, results of operations or cash flows.
	Liquidity
	As of December 31, 2014, we had cash and cash equivalents and trade receivables of approximately $8.0 million and our accounts payable and accrued expenses were approximately $9.1 million. In addition, we have $24.0 million aggregate principal amount of promissory notes and Operational Override payments due prior to December 31, 2015.
	Under the Revolving Credit Facility with SunTrust, the Company has $9 million of available borrowings at December 31, 2014 that could be utilized to fund the payment of accounts payable and accrued expense in excess of cash and cash equivalents. The Company is currently focused on increasing the operations at the transloading facility and expects cash flows from operations to increase due to the fact that it currently owns 100% of DPTS and DPTS Sand, LLC. We believe that the cash flows from operations and the availability under the revolving credit facility will allow us to meet the current obligations of the company in ordinary course of business. However, the Company also plans to discuss with Sun Trust, the possibility of refinancing or restructuring the Tranche B portion of the Revolving Credit Facility if it cannot meet its current obligations. The Company may also need to secure financing through the capital markets, or otherwise, in order to fund future operations and satisfy obligations due. There is no guarantee that any such required financing will be available on terms satisfactory to the Company, if at all, or that the Company will be able to successfully refinance or restructure the Tranche B portion of the Revolving Credit Facility.
	Joint Venture Equity Investment
	The Company used the equity method to account for investments in joint ventures where the Company had significant influence, representing equity ownership of not more than 50%. Effective November 24, 2014, the Company sold its 50% ownership in DPS. In addition, effective November 30, 2014, the Company purchased the remaining ownership interests in Dakota Petroleum Transport Solutions, LLC ("DPTS"), DPTS Marketing LLC ("DPTSM") and DPTS Sand, LLC from its joint venture partner (See Note 13). Prior to the aforementioned transactions, the Company's investments accounted for using the equity method consisted of 50% owned DPTS joint venture, 50% owned DPTSM joint venture, 50% owned DPS joint venture and 50% owned DPTS Sand, LLC joint venture. All of the Company's equity investments had December 31 fiscal year-ends, and the Company recorded its 50% share of the joint ventures' net income or loss based on their most recent annual audited financial statements, if available, or unaudited financial statements if not significant, during the period the equity investments were accounted for using the equity method. The Company's share of the joint ventures' operating results for each period were adjusted for its share of intercompany transactions, which primarily related to rental agreements. Any significant unrealized intercompany profits or losses were eliminated in applying the equity method of accounting.
	Effective at the end of business on December 31, 2013, DPT was appointed the Facility Management Member of DPTS. The appointment as the Facility Management Member resulted in the consolidation of the accounts of DPTS with and into the consolidated financial statements of the Company as of December 31, 2014 and 2013. Accordingly, the accompanying December 31, 2013 consolidated balance sheet and the consolidated statements of operations for the year ended December 31, 2014 include the accounts and operations of DPTS. The operations of DPTS Sand, LLC commenced in June 2014, and the accompanying financial statements include its accounts and results of operations.
	At December 31, 2014, the Company has no investments in joint ventures where it has significant influence, representing equity ownership of not more than 50%, and is not accounting for any investments using the equity method.
	The Company followed applicable equity method authoritative guidance whereby declines in estimated investment fair value below carrying value assessed as other than temporary were recognized as a charge to earnings to reduce carrying value to estimated fair value. The Company periodically evaluated its equity investments for possible declines in value and determined if declines were other than temporary based on, among other factors, the sufficiency and outcome of equity investee performed impairment assessments (which includes third party appraisals and other analyses), the amount and length of time that fair value may have been below carrying value, near-term and longer-term operating and financial prospects of equity investees, and the Company's intent and ability to hold the equity investments for a period of time sufficient to allow for any anticipated recovery.
	Cash and Cash Equivalents
	The Company considers highly liquid investments with insignificant interest rate risk and original maturities of three months or less to be cash equivalents. Cash equivalents consist primarily of interest-bearing bank accounts and money market funds. The Company's cash positions represent assets held in checking and money market accounts. These assets are generally available to the Company on a daily or weekly basis and are highly liquid in nature. Due to the balances being greater than $250,000, the Company does not have FDIC coverage on the entire amount of bank deposits. The Company believes this risk of loss is minimal.
	Accounts Receivable
	Accounts receivable are carried on a gross basis, with no discounting. The Company regularly reviews all aged accounts receivable for collectability and establishes an allowance as necessary for individual customer balances. At December 31, 2014 there was no allowance for doubtful accounts.
	Property and Equipment
	Property and equipment are recorded at cost and depreciated using the straight-line method over their estimated useful lives.
	Estimated useful lives are as follows:
	Site development		15years
	Terminal		13years
	Machinery		5 - 13 years
	Other Property and Equipment		3 - 5 years
	Land		—
	Expenditures for replacements, renewals, and betterments are capitalized. Maintenance and repairs are charged to operations as incurred. Depreciation expense was $4,332,900, $179,546 and $165,313 for the years ended December 31, 2014, 2013 and 2012, respectively. The Company had fixed assets related to in-progress construction of $1,886,470 and $7,551,187 at December 31, 2014 and 2013, respectively. The Company believes the estimated cost to complete construction is approximately $1.8 million. The projects associated with the fixed assets related to in-progress construction at December 31, 2014 and 2013 were undertaken by the joint ventures that funded all endeavors through equity from its members. The Company's policy is to capitalize interest when the construction time for a project is greater than one year.
	Impairment
	FASB Accounting Standards Codification ("ASC") 360-10-35-21 requires that long-lived assets to be held and used be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The determination of impairment is based upon expectations of undiscounted future cash flows, before interest, of the related asset. If the carrying value of the asset exceeds the undiscounted future cash flows, the impairment would be computed as the difference between the carrying value of the asset and the fair value. There was no impairment identified at December 31, 2014, 2013 and 2012.
	Environmental Accrual
	Accruals for estimated costs for environmental obligations generally are recognized no later than the date when the Company identifies what cleanup measures, if any, are likely to be required to address the environmental conditions. Included in such obligations are the estimated direct costs to investigate and address the conditions and the associated engineering, legal and consulting costs. In making these estimates, the Company considers information that is currently available, existing technology, enacted laws and regulations, and its estimates of the timing of the required remedial actions. Such accruals are initially measured on a discounted basis — and are adjusted as further information becomes available or circumstances change — and are accreted up over time. The Company has recorded no liability for environmental obligations as of December 31, 2014 and 2013.
	Income Taxes
	The Company accounts for income taxes under FASB ASC 740-10-30. Deferred income tax assets and liabilities are determined based upon differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. Accounting standards require the consideration of a valuation allowance for deferred tax assets if it is "more likely than not" that some component or all of the benefits of deferred tax assets will not be realized.
	The tax effects from an uncertain tax position can be recognized in the consolidated financial statements only if the position is more likely than not of being sustained if the position were to be challenged by a taxing authority. The Company has examined the tax positions taken in its tax returns and determined that there are no uncertain tax positions. As a result, the Company has recorded no uncertain tax liabilities in its consolidated balance sheet.
	The Company records Goodwill for income tax purposes for the amount that the purchase price paid for an asset or group of assets exceeds the fair value of the assets acquired. The Goodwill is amortized over fifteen years.
	Stock-Based Compensation
	The Company records expenses associated with the fair value of stock-based compensation. For fully vested and restricted stock grants, the Company calculates the stock-based compensation expense based upon estimated fair value on the date of grant. For stock warrants and options, the Company uses the Black-Scholes option valuation model to calculate stock-based compensation at the date of grant. Option pricing models require the input of highly subjective assumptions, including the expected price volatility. Changes in these assumptions can materially affect the fair value estimate.
	Revenue Recognition
	DPTS and DPTS Sand, LLC recognize revenues when the related services are performed, the sales price is fixed or determinable and collectability is reasonably assured. DPTS records the gross sale of fuel-related services when the transloading of petroleum-related products is complete. DPTS Sand, LLC records the gross sale when the transloading of sand-related products is complete.
	Stock Issuance
	The Company records the stock-based compensation awards issued to non-employees and other external entities for goods and services at either the fair market value of the goods received or services rendered or the instruments issued in exchange for such services, whichever is more readily determinable, using the measurement date guidelines enumerated in FASB ASC 505-50-30.
	Earnings Per Share
	Basic earnings per share ("EPS") excludes dilution and is computed by dividing net income (loss) attributable to Company stockholders by the weighted average number of common shares outstanding during the period. Diluted EPS reflects the potential dilution that could occur if common stock equivalents were exercised or converted to common stock. The dilutive effect of common stock equivalents is calculated using the treasury stock method. When a loss from continuing operations exists, all potentially dilutive securities are anti-dilutive and therefore excluded from the computation of diluted EPS. As the Company had a loss for the years ended December 31, 2014, 2013, and 2012, the potentially dilutive shares are anti-dilutive and thus not added into the diluted EPS calculation.
	The following stock options, warrants and restricted stock represent potentially dilutive shares as of December 31, 2014, 2013 and 2012:
			December 31,
			2014		2013		2012
	Restricted Stock			1,031,150		769,063		568,437
	Stock Options			-		415,625		215,625
	Stock Warrants			2,771,000		2,771,000		2,671,000
	Total Potentially Dilutive Shares			3,802,150		3,955,688		3,455,062
	Fair Value Measures
	The Company measures fair value using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, essentially an exit price, based on the highest and best use of the asset or liability. The levels of the fair value hierarchy are:
		Level 1 – Quoted market prices in active markets that are accessible at measurement date for identical assets or liabilities;
		Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and
		Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities and less observable from objective sources.
	Use of Estimates
	The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Such significant estimates include recoverability of property and equipment, depreciable lives for property and equipment, fair value of the Operational Override liability, inputs in the valuation of certain equity transactions, and accounting for income taxes. Actual results may differ from those estimates.
	Non-Controlling Interest
	ASC 810 "Consolidation" requires that a non-controlling interest, previously referred to as a minority interest, be reported as part of equity in the consolidated financial statements and that losses be allocated to the non-controlling interest even when such allocation might result in a deficit balance, reducing the losses attributable to the controlling interest. The Company's non-controlling interest during the year ended December 31, 2014 is due to the non-controlling member of DPTS and DPTS Sand, LLC prior to the Company's purchase of the 50% interest owned by the non-controlling member.
	Principles of Consolidation
	The accompanying consolidated financial statements include the accounts of Dakota Plains Holdings, Inc. and its wholly owned subsidiaries. The accompanying consolidated balance sheet as of December 31, 2014 includes all of the accounts of DPTS, DPTS Sand, LLC and DPTSM. The accompanying consolidated balance sheet as of December 31, 2013 includes all of the accounts of DPTS. The accompanying consolidated statement of operations for the year ended December 31, 2014 includes the accounts of DPTS for the entire year, the accounts of DPTS Sand, LLC since inception and the accounts of DPTSM since the purchase of the 50% interest owned by the Company's former joint venture partner. All significant intercompany accounts and transactions have been eliminated.

Joint Ventures [Abstract]
Joint Ventures	3	Joint Ventures
	Dakota Petroleum Transport Solutions, LLC
	On November 9, 2009, the Company entered into a joint venture with Petroleum Transport Solutions, LLC ("PTS"). The Company and PTS each owned 50% of the outstanding member units of DPTS until the Company purchased the 50% ownership interest of PTS, effective November 30, 2014. The joint venture was formed to engage in the acquisition, construction and operation of a petroleum transloading facility in New Town, North Dakota ("Transloading Facility").
	Each of the members of DPTS was required to make an initial capital contribution of $50,000. Each member received 1,000 member units for their initial capital contribution.
	As part of the joint venture agreement, the Company owns the Transloading Facility and certain equipment acquired and leases the property to DPTS.
	The operations of the Transloading Facility commenced in November 2009. Under provisions of the member control agreement the profits and losses of DPTS were split 50/50, pro rata based on the number of member units outstanding. The cash payments from the joint venture also were paid pro rata based on the number of member units outstanding.
	On June 1, 2012, DPT entered into an amended and restated member control agreement with DPTS and PTS. The amended and restated member control agreement, among other things, incorporated all previous amendments and supplements, extended the initial term through December 31, 2021, and provided for the initial term to automatically extend in two-year intervals unless and until terminated. On August 30, 2012, the parties amended the amended and restated member control agreement to permit certain other ventures. On June 17, 2013, the parties further amended the amended and restated member control agreement to, among other things, extend the initial term through December 31, 2026. On December 31, 2013, the parties entered into the Second Amended and Restated Member Control Agreement ("Revised MCA") that, among other things, named DPT as the Facility Management Member.
	As a result of the Revised MCA, the Company accounted for this joint venture using the equity method of accounting through the end of business on December 31, 2013, at which time it was consolidated. Beginning January 1, 2014, the Company began including the operations of DPTS in its consolidated statements of operations. The Company's share of income from the joint venture is included in other income on the consolidated statements of operations for periods ended December 31, 2013 and 2012. At December 31, 2013, the Company reflected the assets and liabilities of DPTS at carryover basis as summarized in the following table:
			As of
			31-Dec-13

	Supplemental Agreement
	In September 2010, the Company entered into a Supplemental Agreement to the DPTS member control agreement ("Supplemental Agreement"). The purpose of the Supplemental Agreement was to obtain access to site improvements and certain additional transloading equipment necessary to fulfill certain transloading contracts. Under this Supplemental Agreement the Company agreed to provide funds for the site improvements. The total costs incurred for these site improvements were $1,299,201. These costs have been capitalized as property and equipment in the accompanying consolidated balance sheets.
	As part of the Supplemental Agreement, PTS was required to pay all costs for the acquisition of four new transloaders. The total cost of these transloaders was $658,012, with an estimated residual value of $131,602 at the end of the initial Agreement term for a net cost incurred of $526,410.
	To reflect the economics of the $526,410 of costs incurred, the Company recognized rental income of $12,169 and $42,783 for the years ended December 31, 2013 and 2012, respectively. The rental income for the year ended December 31, 2014 was eliminated upon consolidation. No cash was received related to this rental income. The rental income recorded was treated as an increase in the Company's investment in the joint venture.
	In order to render fair and equitable the leases for the additional expenditures by the members relating to the site improvements and new equipment, the Supplemental Agreement included a provision that the Company would receive 75% of the cash distributions from DPTS until the Company had been reimbursed. The additional expenditures would also incur interest at an interest rate of 7% per annum until paid in full. After the Company was reimbursed and received the required interest, the cash distributions reverted back to the 50/50 split as per the original agreement. Only the cash distributions were changed under the Supplemental Agreement. The profit and loss allocations remained the same as the original member control agreement. As of December 31, 2014, the Company had been fully reimbursed for the additional expenditures related to the Supplemental Agreement.
	In the first quarter of 2013, the Company settled an outstanding invoice related to the costs incurred as part of the Supplemental Agreement. The invoice was settled for $21,546 less than the original invoice amount. Based on this the total additional expenditures incurred by the Company were $772,791.
	Rental income related to the Supplemental Agreement was $11,310 and $64,214 for the years ended December 31, 2013 and 2012, respectively. The rental income for the year ended December 31, 2014 was eliminated upon consolidation.
	The Revised MCA, among other things, named DPT as the Facility Management Member. This assumption of control of the day-to-day operations resulted in a change in the Company's method of accounting for the joint venture. Effective December 31, 2013, the Company consolidated the accounts of DPTS into its consolidated balance sheet. Beginning January 1, 2014, the Company began including the operations of DPTS in its consolidated statements of operations.
	Summarized financial information of DPTS when accounted for as an equity method investment is as follows:
			Year Ended
			December 31,
			2013			2012
	Sales		$	17,475,294		$	15,884,822
	Net Earnings			7,926,044			6,491,033
	Company's Share of Equity in Net Earnings			3,963,022			3,245,516
	Total Assets			-			13,652,679
	Total Liabilities			-			2,617,257
	Share of Equity in Net Assets			-			5,517,711
	The balance sheet information as of December 31, 2014 and 2013 and the statement of operations information for the year ended December 31, 2014 has been excluded as they are included in the consolidated financial statements of the Company.
	Pro Forma Information
	The assumption of the control of day-to-day management of the operations was effective end of business December 31, 2013. Therefore, the operating results of DPTS have not been included on the Company's consolidated statements of operations for the years ended December 31, 2013 and 2012. The following audited pro forma results of operations assume that the change in control of day-to-day management of the operations had been effective for the aforementioned periods. Such results are not necessarily indicative of the actual results of operations that would have been realized nor are they necessarily indicative of future results of operations.
	These pro forma amounts have been calculated after adjusting for intercompany amounts. In addition, the equity earnings from the Company's former non-controlling interest in DPTS have been removed.

	DPTS Marketing LLC
	The Company, through its wholly owned subsidiary Dakota Plains Marketing, LLC, entered into a joint venture with PTS. The Company and PTS each owned 50% of the outstanding member units of DPTSM until the Company purchased the 50% ownership interest of PTS, effective November 30, 2014. The joint venture was formed to engage in the purchase, sale, storage, transport and marketing of hydrocarbons produced within North Dakota to or from refineries and other end-users or persons and to conduct trading activities.
	Each of the members of DPTSM was required to make an initial capital contribution of $100. Each member received 1,000 member units for their initial capital contribution.
	Each of the members of DPTSM was also required to make an initial Member Preferred Contribution of $10 million to support the trading activities of the joint venture. The Member Preferred Contributions made entitled the member to receive a cumulative preferred return of 5% per annum. At December 31, 2013, the Company reported a preferred dividend receivable of $252,057 on its consolidated balance sheet. In September 2013, the Company received a payment of $1.1 million related to the cumulative preferred return. This payment was for the cumulative preferred return from the date of the initial $10 million contribution through September 30, 2013. The cumulative preferred return for the period from October 1, 2013 through November 30, 2014 and the initial $10 million contribution were distributed to the Company as part of the Company's purchase of the 50% ownership interest of PTS that was effective on November 30, 2014.
	The operations of DPTSM commenced in May 2011. Under the member control agreement, the profits and losses of DPTSM were split 50/50, pro rata based on the number of member units outstanding. The cash payments from the joint venture were also paid pro rata based on the number of member units outstanding. The Company received its only priority cash distribution payments in April and June 2013.
	On June 1, 2012, DPM entered into an amended and restated member control agreement with DPTSM and PTS. The amended and restated member control agreement, among other things, incorporated all previous amendment and supplements, extended the initial term through December 31, 2021, and provided for the initial term to automatically extend in two-year intervals unless and until terminated. On August 30, 2012, the parties amended the amended and restated member control agreement to permit certain other ventures. On June 17, 2013, the parties further amended the amended and restated member control agreement to extend the initial term through December 31, 2026. On December 31, 2013, the parties entered into the Second Amended and Restated Member Control Agreement that, among other things, increased the operating and accounting fees paid to the member who performs and is solely responsible for purchasing, selling, storing, transporting, marketing and transacting trades in North Dakota crude oil, and entering into related agreements and conducting related activities on behalf of DPTSM ("Trading Member") and amended the limitations on its trading activities.
	The Company accounted for this joint venture using the equity method of accounting until the date it purchased the 50% ownership interest of PTS. The Company's share of the income or loss from the joint venture is included in other income on the consolidated statements of operations, and the Company recorded an investment in DPTSM on its consolidated balance sheet as of December 31, 2013.
	Summarized financial statements of DPTSM when accounted for as an equity method investment is as follows:

Dakota Plains Services, LLC
The Company, through its wholly owned subsidiary Dakota Plains Trucking, LLC, entered into a joint venture with JPND II, LLC ("JPND"). The Company and JPND each owned 50% of the outstanding member units of DPS until the Company sold its 50% ownership to JPND on November 24, 2014. The joint venture was formed to engage in the transportation by road of hydrocarbons and materials used or produced in the extraction of hydrocarbons to or from refineries and other end-users or persons, wherever located, and any other lawful activities as the board of governors determined from time to time.
JPND made an initial capital contribution of $650,000 to DPS. The Company was not required to make a capital contribution. Each member received 1,000 member units in DPS.
The member control agreement of DPS included a provision that JPND would receive all distributions from the joint venture until the aggregate amount of distributions received was equal to their initial capital contribution. The Company received no distributions during the year ended December 31, 2014.
The operations of DPS commenced in September 2012. Under provisions of the member control agreement the profits and losses of DPS were split 50/50, pro rata based on the number of member units outstanding.
The initial term of the joint venture was until December 31, 2022.
Prior to selling its ownership interest, the Company accounted for this joint venture using the equity method of accounting.

Stock-Based Compensation And Warrants	7	Stock-Based Compensation and Warrants
	The Company accounts for stock-based compensation under the provisions of FASB ASC 718-10-55.This standard requires the Company to record an expense associated with the fair value of the stock-based compensation.The Company uses the Black-Scholes option valuation model to calculate stock-based compensation at the date of grant.Option pricing models require the input of highly subjective assumptions, including the expected volatility.For warrants and options granted to employees and directors, the Company uses the simplified method to determine the expected term due to the lack of sufficient historical data.Changes in these assumptions can materially affect the fair value estimate.The fair value of the warrants and options are recognized as compensation or interest expense over the vesting term.
	Warrants
	Warrants Granted November 1, 2012
	On November 1, 2012, the Company issued warrants to a consultant, pursuant to a consulting agreement, to purchase a total of 50,000 shares of common stock exercisable at $3.28 per share. The total fair value of the warrants was calculated using the Black-Scholes option valuation model based on factors present at the time the warrants were issued. The warrants can be exercised at any time until the warrants expire on November 1, 2016. The consulting agreement terminated on November 1, 2013. The Company recorded general and administrative expense of $62,788 for the year ended December 31, 2013, related to these warrants.
	Warrants Granted November 2, 2012
	On November 2, 2012, in conjunction with the private placement of promissory notes (see Note 8), the Company issued warrants to purchase a total of 921,000 shares of common stock exercisable at $4.00 per share. The fair value of the warrants was reported as a debt discount and netted against the amount due on the promissory notes on the consolidated balance sheet. The warrants can be exercised at any time until the warrants expire in October 31, 2017.
	Using the Black-Scholes option valuation model the Company determined the fair value of the warrants to be $1,264,985 and allocated the debt proceeds in accordance with the relative fair value method. The Company recorded a $1,048,889 discount on the promissory notes representing the allocation of the relative fair value to the warrants. The debt discount was being amortized over the term of the promissory notes. The unamortized debt discount was written off in December 2014 when the promissory notes were satisfied.For the years ended December 31, 2014, 2013 and 2012, the Company recognized interest expense of $640,985, $349,632 and $58,272, respectively, related to the amortization of this debt discount.

	On January 1, 2013, the Company issued warrants to a consultant, pursuant to a consulting agreement, to purchase a total of 100,000 shares of common stock exercisable at $3.25 per share.

The warrants can be exercised at any time until the warrants expire on February 15, 2018. The consulting agreement terminated on May 31, 2013. The Company recorded general and administrative expense of $145,875 for the year ended December 31, 2013.

	At the Borrowers' option, borrowings under the Credit Facility may be either (i) the "Base Rate" loans, which bear interest at the highest of (a) the rate which the Administrative Agent announces from time to time as its prime lending rate, as in effect from time to time, (b) 1/2 of 1% in excess of the federal funds rate and (c) Adjusted LIBOR (as defined in the Credit Agreement) determined on a daily basis with a one (1) month interest period, plus one percent (1.00%) or (ii) "Eurodollar" loans, which bear interest at Adjusted LIBOR, as determined by reference to the rate for deposits in dollars appearing on the Reuters Screen LIBOR01 Page for the respective interest period.
	The Credit Agreement requires the Company to maintain a minimum fixed charge coverage ratio and a maximum total debt to EBITDA (earnings before income taxes, depreciation expense and amortization), or leverage ratio.

The New Notes bore interest at the rate of 12% per annum, with interest payable in arrears on the last day of each fiscal quarter.
	The New Notes included an additional payment provision that was considered and embedded derivative. In May 2012, the embedded derivative was satisfied with the issuance of promissory notes in the aggregate amount of $27,663,950 and 1,296,963 shares of the Company's common stock. The increase in the fair value of the embedded derivative during the year ended December 31, 2012, $27,311,800, was recorded as interest expense on the consolidated statement of operations.
	Private Placement of Debt
	On November 2, 2012, the Company issued promissory notes in the amount of $6,140,000. The issuance of these promissory notes resulted in proceeds to the Company of approximately $5,945,000, net of commissions and finance costs paid. The promissory notes bore interest at the rate of 12% per annum.
	In conjunction with the issuance of the promissory notes, the Company issued warrants to purchase 921,000 shares of our common stock, exercisable at $4.00 per share. The warrants expire on October 31, 2017.
	The Company recorded $1,048,889 of debt discount against these promissory notes representing the allocation of the relative fair value to the warrants issued (see Note 7). The debt discount was being amortized over the term of the promissory notes using the straight-line method, which approximated the effective interest method. The unamortized debt discount was written off in December 2014 when the promissory notes were satisfied. For the years ended December 31, 2014, 2013 and 2012, the Company recognized interest expense of $640,985, $349,632 and $58,272, respectively, related to this debt discount.
	The Company incurred finance costs of $195,062 related to these notes, which was being amortized over the term of the notes and included in interest expense on the consolidated statement of operations. The unamortized finance cost was written off in December 2014 when the promissory notes were satisfied. The interest expense recorded for the years ended December 31, 2014, 2013 and 2012 was $119,202, $65,021 and $10,839, respectively.
	Amended Election, Exchange and Loan Agreements
	In addition, on November 2, 2012, pursuant to the Amended Election, Exchange and Loan Agreements, the Company repaid the outstanding principal to a holder of the New Notes in the amount of $500,000. The term of the remaining $8.5 million in New Notes was extended using two different maturity dates. $4,605,300 of the New Notes was extended to March 1, 2014 and $3,894,700 was extended to October 31, 2015. All of the holders of the New Notes agreed to surrender and void the $27,663,950 of promissory notes and 1,296,963 shares of the Company's common stock received April 21, 2012, related to the additional payment provision in the New Notes.
	As a result of the revaluation of the additional payment provision and revised elections of the holders, the Company issued promissory notes in the aggregate of $11,965,300 and 1,757,075 shares of its common stock. The promissory notes bore interest at the rate of 12% per annum.
	Gain on Extinguishment of Debt – Year Ended December 31, 2012
	The Company assessed the impact of the Amended Election, Exchange and Loan agreements and whether it should be accounted for as an extinguishment of debt and the issuance of new debt or a modification of the existing debt. The present value of the remaining payments was substantially different than the present value of the original agreements. Therefore, the Company reported the transaction as an extinguishment of debt. Since the exchange was accounted for as an extinguishment of debt, the decrease in fair value of the Company's liabilities (net of cost incurred and the increased fair value of the common stock issued) was reported as gain on extinguishment of debt on the consolidated statement of operations.
	Adjustment, Extension and Loan Agreement
	On December 10, 2013, the Company entered into an Adjustment, Extension and Loan Agreement ("Loan Agreements") with each of the holders of the Company's New Notes, pursuant to which the Company issued new debt securities in connection with an extension and reduction of the outstanding debt.
	Pursuant to the Loan Agreements, the holders of the New Notes due March 1, 2014 agreed to extend the maturity dates of such notes to September 30, 2014.
	In addition, the holders of the promissory notes issued under the Amended Election, Exchange and Loan Agreements agreed to revalue the additional payment provision. This revaluation resulted in a reduction of the principal amount of the promissory notes by $1,945,156. In connection with the Loan Agreements, in exchange for the original promissory notes issued, the Company issued $10,020,143 principal amount of 12% amended and restated senior unsecured promissory notes due October 31, 2015. Additionally, the holders agreed to surrender 304,732 shares of the Company's common stock issued as part of the Amended Election, Exchange and Loan Agreements. The surrender of these shares was accounted for as decrease in common stock and an increase in additional paid in capital based on the $.001 par value of the shares. The amended and restated senior unsecured promissory notes bore interest at the rate of 12% per annum.
	The Loan Agreements also provided that, if the Company completes a sale of not less than $5.0 million worth of capital stock, either registered or through a private placement (a "Qualified Equity Placement"), on or before December 10, 2015, the Company would use not less than 50% of the proceeds from such sale to repay, pro rata in order of maturity, all or a portion of the promissory notes due September 30, 2014 and $3,894,700 principal amount of New Notes due October 2015. Additionally, if the Company completed a Qualified Equity Placement on or before December 10, 2014, then, the Company could elect to convert $10,020,143 aggregate principal amount of the amended and restated senior unsecured promissory notes due October 2015 into shares of common stock at the per-share price used in the Qualified Equity Placement. The registered direct offering of the Company's common stock, which closed on December 16, 2013, was a Qualified Equity Placement, and the Company exercised the right to convert the amended and restated senior unsecured promissory notes due October 2015, which resulted in the issuance of 4,660,535 additional shares of the Company's common stock based on an offering price of $2.15 per share.
	The Company also repaid the outstanding principal on the $4,605,300 of the promissory notes due September 30, 2014 and $2,317,383 of outstanding principal on New Notes with a maturity of October 31, 2015.
	Gain on Extinguishment of Debt – Year Ended December 31, 2013
	The Company assessed the impact of the Adjustment, Extension and Loan Agreement and whether it should be accounted for as an extinguishment of debt and the issuance of new debt or a modification of the existing debt. The present value of the remaining payments was substantially different than the present value of the original agreements. Therefore, the Company reported the transaction as an extinguishment of debt. Since the exchange was accounted for as an extinguishment of debt, the decrease in fair value of the Company's liabilities (net of cost incurred) was reported as gain on extinguishment of debt of $1,726,515, or $0.04 per share, on the consolidated statement of operations.
	Pioneer Terminal
	In June 2013, DPT ("Borrower") entered into a credit agreement with WFS. The agreement provided the Borrower with a $20 million delayed draw term loan facility (the "Facility") to finance the Borrower's share of improvements to be made to the Pioneer Terminal in New Town, North Dakota. The Facility was secured by a mortgage on a majority of the land owned by the Company in New Town, North Dakota as well as a pledge of the equity owned by the Borrower in DPTS.
	The Facility bore interest at a rate per annum equal to nine percent (9%). There was $7.5 million outstanding under the Facility at December 31, 2013.
	The agreement contained customary affirmative and negative covenants, including covenants that restricted the right of the Borrower to incur indebtedness, merge, lease, sell or otherwise dispose of assets, make investments and grant liens on their assets.
	The Company incurred finance costs of $9,783 related to the agreement, which was amortized and included in interest expense on the consolidated statement of operations. The interest expense recorded for the years ended December 31, 2014 and 2013 was $4,076 and $5,707, respectively.
	The Senior Unsecured Promissory Notes and credit agreement with WFS were paid in full and terminated when the Company entered into the Revolving Credit and Term Loan Agreement with SunTrust Bank on December 5, 2014.
	The annual maturities related to the Revolving Credit and Term Loan Agreement are as follows:
		Year Ending December 31,	Amount
		2015	$	23,250,000
		2016		1,500,000

Income Taxes [Abstract]
Income Taxes	9	Income Taxes
	The Company utilizes the asset and liability approach to measuring deferred tax assets and liabilities based on temporary differences existing at each balance sheet date using currently enacted tax rates in accordance with FASB ASC 740-10-30. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment.
	The income tax benefit for the years ended December 31, 2014, 2013, and 2012 consists of the following:
			2014			2013			2012
	Current Income Taxes

	The following is a reconciliation of the reported amount of income tax benefit for the years ended December 31, 2014, 2013 and 2012 to the amount of income tax benefit that would result from applying the statutory rate to the pretax loss.

	Total Deferred Tax Assets (Liabilities)		$	29,028,000		$	3,881,000
	The Company has no liabilities for unrecognized tax benefits.
	The Company's policy is to recognize potential interest and penalties accrued related to unrecognized tax benefits within income tax benefit. For the years ended December 31, 2014, 2013 and 2012, the Company did not recognize any interest or penalties in the consolidated statement of operations, nor did it have any interest or penalties accrued in the consolidated balance sheet at December 31, 2014 and 2013 relating to unrecognized benefits.
	The Company reported a net operating loss ("NOL") carry forward for federal tax purposes of approximately $24.3 million and $19.3 million at December 31, 2014 and 2013, respectively. The net operating loss carry forward that was generated in the year ended December 31, 2013 was caused by the Company's pro rata share of the bonus depreciation that DPTS recorded related to the Pioneer Terminal for income tax purposes. The Company anticipates taxable income beginning in the year ending December 31, 2015 and going forward based on its recent purchase of PTS's ownership interests in DPTS and DPTS Sand, LLC and the more favorable terms of the debt with SunTrust. As part of the transaction to purchase the membership units owned by PTS, the Company recorded Goodwill for income tax purposes for the amount that the purchase price exceeded the fair value of the assets acquired. The Company has recorded a deferred tax asset for the tax Goodwill in the amount of $6.2 million at December 31, 2014. This deferred tax asset will be reduced as the Company amortizes the Goodwill. In addition, the Company has recorded a deferred tax asset of $16.9 million for the operational override liability. The liability will be reduced for book purposes when paid and recorded as a taxable deduction at the time of payment. The deferred tax asset will be reduced as these payments are made.
	The Company reported a net deferred tax asset of $29,028,000 on its consolidated balance sheet as of December 31, 2014. GAAP requires the consideration of a valuation allowance for deferred tax assets if it is "more likely than not" that some component or all of the benefits of deferred tax assets will not be realized. The Company reported a valuation allowance of $306,000 at December 31, 2014 related to state net operating loss carry forwards. The Company accumulated net operating losses in states other than North Dakota due to the operations of DPTSM. The Company will no longer file tax returns in these states now that the operations of DPTSM have been discontinued.
	The 2013, 2012 and 2011 tax years remain open to examination for federal income tax purposes and by the other major taxing jurisdictions to which the Company is subject.

	The Company's financial instruments include cash and cash equivalents, trade receivables, other receivables, accounts payable, and promissory notes. The carrying amount of cash and cash equivalents, trade receivables, other receivables and accounts payable approximate fair value because of their immediate or short-term maturities. The carrying amounts of the Company's promissory notes outstanding approximate fair value because its current borrowing rates do not materially differ from market rates for similar borrowings.

Fair Value [Abstract]
Fair Value	12	Fair Value
	FASB ASC 820-10-55 defines fair value, establishes a framework for measuring fair value under GAAP and enhances disclosures about fair value measurements. Fair value is defined under FASB ASC 820-10-55 as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value under FASB ASC 820-10-55 must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value.
	As of December 31, 2013, the Company had no financial instruments measured at fair value on a recurring basis in the consolidated balance sheet. Level 2 liabilities consist of the promissory notes (see Note 8).
	The following schedule summarizes the valuation of financial instruments measured at fair value on a recurring basis in the consolidated balance sheet as of December 31, 2014:
	Fair Value Measurements at December 31, 2014 Using
			Quoted Prices In			Significant Other		Significant

	The level 3 liability consists of the contingent liability related to the Operational Override (See Note 13). There were no transfers between any of the fair value levels during the years ended December 31, 2014 and 2013.
	The following table provides a reconciliation of the beginning and ending balances for the liability measured at fair value using significant unobservable inputs (Level 3) during the year ended December 31, 2014:

	As of March 22, 2012, the issued and outstanding common stock of Dakota Plains before the Initial Merger was converted into the right to receive an aggregate of 37,014,018 shares of the Company's common stock, all of which were "restricted securities" under Rule 144. Of those shares, 530,000 were restricted shares of the Company's common stock issued under certain employment agreements in exchange for 530,000 shares of similarly restricted Dakota Plains' common stock. In addition, the outstanding options issued by Dakota Plains before the Initial Merger were converted into options to purchase an aggregate of 250,000 shares of the Company's common stock and the outstanding warrants issued by Dakota Plains before the Initial Merger were converted into warrants to purchase an aggregate of 4,150,000 shares of the Company's common stock. The shareholders of the Company before the Initial Merger retained 640,200 shares of common stock, representing approximately 1.7% of its outstanding shares of common stock immediately after the Initial Merger.
	In March 2012, Dakota Plains Holdings, Inc., the surviving corporation from the Initial Merger and then a wholly owned subsidiary of the Company, merged with and into MCT Holding Corporation (the "Second Merger"). Pursuant to the plan of merger governing the Second Merger, the Company changed its name from "MCT Holding Corporation" to "Dakota Plains Holdings, Inc."

Membership Interest Purchase Agreement	13	Membership Interest Purchase Agreement
	On December 5, 2014, the Company entered into a Membership Interest Purchase Agreement with DPT, Dakota Plains Sand, LLC, DPM and PTS. Pursuant to the Membership Interest Purchase Agreement, in exchange for $43 million in cash and an Operational Override (as defined below), DPT acquired all of the limited liability company membership interests of DPTS owned by PTS, Dakota Plains Sand, LLC acquired all of the limited liability company membership interests of DPTS Sand, LLC owned by PTS, and DPM acquired all of the limited liability company membership interests of DPTSM owned by PTS. As a result of the transactions, through ownership of its wholly owned subsidiaries, the Company became the sole member of DPTS, DPTS Sand, LLC and DPTSM.
	In addition to $43 million in cash paid to PTS at closing, the Company agreed to pay to PTS an amount equal to $0.225 per barrel of crude oil arriving at the current transloading facility located in New Town, North Dakota, up to a maximum of 80,000 barrels of crude oil per day through December 31, 2026 (the "Operational Override"). In the event such Operational Override payments, in the aggregate, are less than $10 million, then the Company is obligated to pay PTS the difference on or before January 31, 2027.
	At any time the Company may pay PTS an amount equal to the then-present value (using a nine percent (9%) discount rate) of the maximum remaining Operational Override payments assuming maximum volume for the period between the pre-payment date and December 31, 2026. If such early payment is made, the Company will have no further obligations related to the Operational Override.
	The Membership Interest Purchase Agreement contains certain representations, warranties, covenants and indemnification obligations of the parties.
	In connection with the Membership Interest Purchase Agreement, the Company entered into an Indemnification and Release Agreement dated December 5, 2014 with WFS (the "Indemnification and Release Agreement"). Pursuant to the Indemnification and Release Agreement, WFS, on behalf of itself and its direct and indirect subsidiaries, agreed to indemnify the Company, DPTS, DPTSM, and each of their respective officers, managers, directors, employees, affiliates, members, and stockholders, for third party claims in connection with, relating to, or otherwise arising from the train car derailment that occurred in Lac-Mégantic, Quebec, on July 6, 2013 (the "Derailment"). In addition, the Company, DPT and DPM, on behalf of itself and each such entity's direct and indirect subsidiaries, agreed to indemnify WFS and WFS's officers, managers, directors, employees, affiliates, members, and stockholders for (i) fifty percent (50%) of the documented out-of-pocket costs and expenses incurred by any WFS party as a result of or arising out of certain obligations to railcar lessors; and (ii) fifty percent (50%) of the documented out-of-pocket defense costs and legal expenses incurred by any WFS party in connection with the Derailment. The Company and its affiliates' total exposure under the indemnification is limited to $10 million in the aggregate. The indemnification obligations are net of any insurance proceeds received. To support its indemnification obligations, the Company placed $3 million of cash in escrow, which is included on the consolidated balance sheet as of December 31, 2014.
	In connection with the indemnification, each of the Company and WFS, on its behalf and on behalf of its affiliates, released the other party and its affiliates from any claims arising in connection with the Derailment, other than those for which indemnification is provided under the Indemnification and Release Agreement.
	Pursuant to a Guaranty and Security Agreement, dated December 5, 2014 (the "Seller Guaranty and Security Agreement"), made by DPT, Dakota Plains Sand, LLC, DPM, the Company and certain subsidiaries of the Company, the Company's obligations under Section 2.2(b) of the Membership Interest Purchase Agreement in respect of the Operational Override, the Company's obligations in the Indemnification and Release Agreement and the obligations of DPTSM under five Amended and Restated Railcar Sublease Agreements between DPTSM and Western Petroleum Company are guaranteed by DPT, Dakota Plains Sand, LLC, DPM, the Company and certain subsidiaries of the Company, and are secured by a second priority lien on all of the assets of such parties.
	In connection with the Membership Interest Purchase Agreement, the following agreements were terminated: (a) that certain Member Control Agreement of DPTS Sand, LLC, effective as of June 1, 2014, by and among Dakota Plains Sand, LLC, PTS, and DPTS Sand, LLC; (b) that certain Second Amended and Restated Member Control Agreement of DPTS effective as of December 31, 2013, by and among DPT, PTS and DPTS; and (c) that certain Second Amended and Restated Member Control Agreement of DPTSM, effective as of December 31, 2013, by and among DPM, PTS, and DPTSM; provided DPM and its affiliates will remain subject to the restrictions against purchasing, selling, storing, transporting or marketing crude oil originating from production fields anywhere in North Dakota, or conducting any trading activities related thereto, until June 5, 2015, but shall be permitted to sublease and lease-for-trip railcars to transport crude oil, and transport any other materials (including crude oil) by road.
	Operational Override
	As part of the Membership Interest Purchase Agreement, the Company agreed to pay a quarterly Operational Override payment to PTS through December 31, 2026. The payments are due within 45 days of the end of each calendar quarter. In the event such Operational Override payments, in the aggregate, are less than $10 million, then the Company is obligated to pay PTS the difference on or before January 31, 2027.
	The Company calculated an initial liability of $45.3 million related to the Operational Override. The initial Operational Override was calculated based on the Company's estimated daily throughput from December 1, 2014 through December 31, 2026; discounted at an interest rate of 9%.
	Annual maturities of the Operational Override are as follows:
		Year Ending December 31,			Amount
	2015				$	715,497
	2016					1,383,232

	Railcar Sublease Agreements
	As part of the Membership Interest Purchase Agreement, the Company, through DPTSM, entered into five Amended and Restated Railcar Sublease Agreements with Western Petroleum Company ("Amended Sublease Agreements"). Under the Amended Sublease Agreements, DPTSM will sublease a total of 872 railcars from Western Petroleum Company subject to the terms, covenants, provisions, conditions, and agreements contained in the master railcar leases between the original lessors and Western Petroleum Company. The term of the Amended Sublease Agreements shall be from December 5, 2014 (the "Effective Date") until the end of the term of the applicable schedule to the respective master railcar lease. The last of the master railcar leases expires in August 2021.
	Within thirty 30 days after the Effective Date, Western Petroleum Company delivered to DPTSM a certain set of railcars as identified in a schedule included with the Amended Sublease Agreements. For the period (the "Suspension Period") beginning on the Effective Date and ending on June 1, 2015 (the "Suspension Termination Date"), the Amended Sublease Agreements as they relate to certain other railcars identified in an additional schedule (the "Suspended Cars") shall be temporarily suspended to permit Western Petroleum Company to retain the Suspended Cars. No later than 30 days after the Suspension Termination Date, Western Petroleum Company will deliver the Suspended Cars to DPTSM at the Company's transloading facility located in New Town, North Dakota, unless an alternate location is agreed to. The Amended Sublease Agreements are being accounted for as operating leases.
	DPTSM assumes and accepts the responsibility for any charges incurred between the time of delivery of the railcars to DPTSM under the Amended Sublease Agreements and redelivery of the railcars to Western Petroleum Company at the conclusion of the term, including, but not limited to, charges resulting from demurrage, track storage, switching, detention, freight or empty movements made by the railcars upon each railroad over which the railcars shall move during the term of the Amended Sublease Agreements, as well as any other charges set forth in the master railcar leases. The total lease expense under the Amended Sublease Agreements was approximately $275,000 for the year ended December 31, 2014.
	Minimum future base lease payments under the Amended Sublease Agreements are as follows:
		Year Ending December 31,			Amount
	2015				$	5,731,000

	Lac-Mégantic, Quebec
	We and certain of our subsidiaries, including DPTS and DPTSM, are among the many defendants named in various lawsuits relating to the derailment of a Montreal Main & Atlantic Railroad, Ltd. ("MM&A") train in Lac-Mégantic, Quebec. We believe all claims asserted against us and our subsidiaries are without merit and we intend to vigorously defend against such claims.
	On July 6, 2013, an unmanned freight train operated by MM&A with 72 tank cars carrying approximately 50,000 barrels of crude oil rolled downhill and derailed in Lac-Mégantic, Quebec. The derailment resulted in significant loss of life, damage to the environment from spilled crude oil and extensive property damage. DPTSM, a crude oil marketing joint venture in which, at the time of the derailment, we indirectly owned a 50% membership interest, and currently own 100% of the membership interest, subleased the tank cars involved in the incident from an affiliate of our former joint venture partner. An affiliate of our former joint venture partner owned title to the crude oil being carried in the derailed tank cars. DPTS, a crude oil transloading joint venture in which, at the time of the derailment, we also indirectly owned a 50% membership interest, and currently own 100% of the membership interest, arranged for the transloading of the crude oil for DPTSM into tank cars at DPTS's facility in New Town, North Dakota. A different affiliate of our former joint venture partner contracted with Canadian Pacific Railway ("CPR") for the transportation of the tank cars and the crude oil from New Town, North Dakota to a customer in New Brunswick, Canada. CPR subcontracted a portion of that route to MM&A.
	On July 15, 2013, four named parties filed a petition in the Canadian Province of Quebec seeking permission from the court to pursue a class action seeking to recover compensatory and punitive damages along with costs. On June 18, 2014 the petitioners sought permission from the Quebec Superior Court to discontinue the proceedings without prejudice against us and our two subsidiaries Dakota Plains Marketing LLC and Dakota Plains Transloading LLC. The Court granted permission for the discontinuance, and consequently those companies have been removed from the proceeding; however, the most recent iteration of the petition, filed on July 7, 2014, still includes DPTS and DPTSM, along with over 30 third parties, including CPR, MM&A and certain of its affiliates, several manufacturers and lessors of tank cars, as well as the intended purchaser and certain suppliers of the crude oil. The petition generally alleges wrongful death and negligence in the failure to provide for the proper and safe transportation of crude oil. We believe these claims against DPTS and DPTSM are without merit and intend to vigorously defend against such claims and pursue any and all defenses available.
	Around July 29, 2013, nineteen individuals filed lawsuits in Cook County, Illinois seeking unspecified damages for their injuries from the accident. The lawsuits assert claims for negligence against the eight defendants noted above. On August 7, 2013, MM&A filed a Chapter 11 voluntary petition in the bankruptcy court in Maine. On August 29, 2013, the defendants jointly removed the cases from state court in Cook County to the United States District Court in the Northern District of Illinois. On September 13, 2013, the bankruptcy trustee for MM&A, and WFS and Petroleum Transport Solutions, LLC filed motions seeking to transfer the nineteen personal injury cases from federal court in Illinois to the United States District Court for the District of Maine (the "ME District Court"). On March 21, 2014, the ME District Court granted the transfer motion. On April 4, 2014, the plaintiffs filed a motion for reconsideration of the order granting the transfer motion and a motion requesting the ME District Court abstain from exercising jurisdiction over the cases. The motion for reconsideration was denied and the motion for abstention remains pending. On May 1, 2014, the plaintiffs appealed the ME District Court's order granting the transfer motion to the First Circuit Court of Appeals. On June 17, 2014, the ME District Court entered a consent order staying proceedings in the transferred cases pending the appeal. On September 25, 2014, the First Circuit Court of Appeals ordered plaintiffs to voluntarily dismiss their appeal or show cause why their appeal should not be dismissed for lack of jurisdiction. The parties have responded to the First Circuit's order to show cause, and its decision is pending.
	We believe these claims against us and certain of our subsidiaries, including DPTS and DPTSM, are without merit and intend to vigorously defend against such claims and pursue any and all defenses available.
	As a result of the Lac-Mégantic derailment, the Canadian Transportation Safety Board is conducting an investigation into the cause of the derailment and the events surrounding it. In addition, the Quebec police are conducting a criminal investigation and are reported to be coordinating with Canadian and U.S. law enforcement authorities.
	Additional claims, lawsuits, proceedings, investigations and orders may be filed, commenced or issued with respect to the incident, which may involve civil claims for damages or governmental investigative, regulatory or enforcement actions against us.
	On December 5, 2014, we entered into an Indemnification and Release Agreement with WFS. Under this agreement, WFS, on behalf of itself and its direct and indirect subsidiaries, has agreed to indemnify us, each of our subsidiaries, including DPTS and DPTSM, for third party claims for bodily injury, death, property damage, economic loss, loss of consortium, loss of income and similar claims in connection with, relating to, or otherwise arising from the derailment, in each case solely to the extent not covered by insurance or otherwise paid for by third parties. In addition, we agreed to indemnify WFS for (i) fifty percent (50%) of the documented out-of-pocket costs and expenses incurred by any WFS party as a result of or arising out of certain obligations to railcar lessors; and (ii) fifty percent (50%) of the documented out-of-pocket defense costs and legal expenses incurred by any WFS party in connection with the derailment not otherwise covered by insurance. However, our total exposure under this indemnification is limited to $10 million in the aggregate. All of the indemnification obligations are net of any insurance proceeds received.
	We are currently unable to determine the probability of loss or reasonably estimate a range of potential losses related to the aforementioned proceedings. Accordingly, we have not made any provisions for these potential losses in our consolidated financial statements
	Dakota Petroleum Transport Solutions, LLC
	TJMD, LLP v. Dakota Petroleum Transport Solutions, LLC
	Since October 2012, DPTS has been involved in litigation with TJMD, LLP, a North Dakota limited liability partnership ("TJMD") arising out of the termination of TJMD as operator of the transloading facility, which DPTS leases for the use and benefit of their business. TJMD alleges that a wrongful termination without cause on 90-days written notice occurred in June 2012 under the implied covenant of good faith and fair dealing, and a second wrongful termination occurred in September 2012, when DPTS finally terminated the contract before the end of the 90-day period. TJMD is seeking payment for work performed prior to the final, September termination, as well as, monetary damages for future losses, and other relief. Because the outcome of litigation is inherently uncertain, DPTS cannot estimate the possible loss or range of loss for this matter. DPTS intends to vigorously defend against this claim. As of December 31, 2014, DPTS has not recorded any accruals associated with this legal claim.
	Dakota Petroleum Transport Solutions, LLC v. TJMD, LLP, et al.
	Since April 2013, DPTS has been involved in litigation with TJMD, Rugged West Services, LLC, a foreign limited liability company ("Rugged West"), and JT Trucking, a foreign limited liability company ("JT"), arising out of crude oil spills that occurred at DPTS's transloading facility while TJMD was operating the facility. DPTS leases the facility for the use and benefit of their business. Trucks haul crude oil to the transloading facility where crude is moved onto railcars and shipped to various locations across the country. DPTS has asserted a claim against TJMD for contractual liability because TJMD must indemnify DPTS for cleanup and remediation expenses incurred as the result of the crude oil spills, based on Service Agreements TJMD entered into with DPTS which provide for contractor indemnification. DPTS has asserted claims against TJMD, Rugged West and JT for negligence in causing or allowing the spills to occur which proximately caused damages to DPTS, entitling DPTS to recovery. DPTS has also asserted claims against TJMD, Rugged West and JT for trespass and nuisance, claiming the defendants exceeded the consent to be on the property, entitling DPTS to recovery.
	TJMD has filed third-party complaints against several trucking companies for indemnification and contribution. Originally, thirteen third-party defendants were named – Deer Valley Trucking, Inc., Hofmann Trucking, LLC, LT Enterprises, Inc., Mad Dog Trucking, Inc., Mann Enterprises, LLC, Missouri Basin Materials, Inc., Nickelback, Inc., Red Rock Transportation, Inc., Safe Rack, LLC, Southern Energy Transportation, Inc., Taylor Trucking, Wylie Bice Trucking, LLC, and Basin Western, Inc. Third-party defendant LT Enterprises also sued Donald Compton d/b/a DC Express, as a fourth-party defendant, claiming DC Express must defend and indemnify LT Enterprises due to a contract entered into between the parties. However, that fourth-party defendant has now been dismissed. Deer Valley Trucking has also been dismissed without prejudice. Pursuant to settlement agreements and releases entered into between the parties, stipulations for dismissal have been filed with the Court for Nickelback, Inc. and Missouri Basin Materials, Inc. to be dismissed with prejudice. Nickelback and Missouri Basin have paid to DPTS the full amount of remediation costs associated with the spills attributable to them.
	DPTS prevailed on a summary judgment motion against JT Trucking, LLC, due to JT's failure to Answer or otherwise appear in the matter. DPTS continues to actively attempt to recover cleanup and remediation costs on a spill-by-spill basis from each of the trucking companies involved in the specific spills, and also from TJMD. Because the outcome of litigation is inherently uncertain, we cannot estimate the possible recovery for this matter at this time. DPTS is vigorously pursuing its claims.

	Dec. 31, 2014
Summary Of Significant Accounting Policies [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements
	From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board ("FASB") that are adopted by the Company as of the specified effective date. If not discussed, management believes that the impact of recently issued standards, which are not yet effective, will not have a material impact on the Company's consolidated financial statements upon adoption.
	In July 2013, the FASB issued Accounting Standards Update ("ASU") No. 2013-11 "Income Taxes – Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carry Forward, a Similar Tax Loss, or a Tax Credit Carry Forward Exists" which provides that entities should present the unrecognized tax benefit as a reduction of the deferred tax asset for a net operating loss ("NOL") or similar tax loss or tax credit carry forward rather than as a liability when the uncertain tax position would reduce the NOL or other carry forward under the tax law. The ASU is effective for annual and interim periods for fiscal years beginning on or after December 15, 2013. The Company adopted this ASU effective January 1, 2014. The adoption of this update did not have a material impact on the Company's consolidated results of operations, financial position or disclosures.
	In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers". The standard's core principle is that an entity shall recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard generally requires an entity to identify performance obligations in its contracts, estimate the amount of variable consideration to be received in the transaction price, allocate the transaction price to each separate performance obligation, and recognize revenue as obligations are satisfied. The standard will be effective for annual and interim periods beginning after December 15, 2016. The standard allows for either full retrospective adoption, meaning the standard is applied to all periods presented in the financial statements, or modified retrospective adoption, meaning the standard is applied only to the most current period presented. The Company is currently evaluating the impact of the provisions of ASU 2014-09; however, the standard is not expected to have a material effect on the Company's consolidated financial position, results of operations or cash flows.
	In April 2014, the FASB issued ASU No. 2014-8, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity". This ASU changes the requirements for reporting discontinued operations to disposals of components of an entity that represent strategic shifts that have a major effect on an entity's operations and financial results. The standard also expands the disclosures for discontinued operations and requires new disclosures related to individually material disposals that do not qualify for discontinued operations reporting. The guidance is effective for interim and annual periods beginning after December 15, 2014, and should be applied prospectively. Early adoption is permitted. The Company is currently evaluating the impact of adoption of this ASU on its consolidated financial statements.
	In June 2014, the FASB issued ASU 2014-12, "Compensation - Stock Compensation" effective for annual periods and interim periods within those periods beginning after December 15, 2015. The amendments require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. The Company is currently evaluating the impact of the provisions of ASU 2014-12, however, the standard is not expected to have a material effect on the Company's consolidated financial position, results of operations or cash flows.
Liquidity	Liquidity
	As of December 31, 2014, we had cash and cash equivalents and trade receivables of approximately $8.0 million and our accounts payable and accrued expenses were approximately $9.1 million. In addition, we have $24.0 million aggregate principal amount of promissory notes and Operational Override payments due prior to December 31, 2015.
	Under the Revolving Credit Facility with SunTrust, the Company has $9 million of available borrowings at December 31, 2014 that could be utilized to fund the payment of accounts payable and accrued expense in excess of cash and cash equivalents. The Company is currently focused on increasing the operations at the transloading facility and expects cash flows from operations to increase due to the fact that it currently owns 100% of DPTS and DPTS Sand, LLC. We believe that the cash flows from operations and the availability under the revolving credit facility will allow us to meet the current obligations of the company in ordinary course of business. However, the Company also plans to discuss with Sun Trust, the possibility of refinancing or restructuring the Tranche B portion of the Revolving Credit Facility if it cannot meet its current obligations. The Company may also need to secure financing through the capital markets, or otherwise, in order to fund future operations and satisfy obligations due. There is no guarantee that any such required financing will be available on terms satisfactory to the Company, if at all, or that the Company will be able to successfully refinance or restructure the Tranche B portion of the Revolving Credit Facility.
Joint Venture Equity Investment	Joint Venture Equity Investment
	The Company used the equity method to account for investments in joint ventures where the Company had significant influence, representing equity ownership of not more than 50%. Effective November 24, 2014, the Company sold its 50% ownership in DPS. In addition, effective November 30, 2014, the Company purchased the remaining ownership interests in Dakota Petroleum Transport Solutions, LLC ("DPTS"), DPTS Marketing LLC ("DPTSM") and DPTS Sand, LLC from its joint venture partner (See Note 13). Prior to the aforementioned transactions, the Company's investments accounted for using the equity method consisted of 50% owned DPTS joint venture, 50% owned DPTSM joint venture, 50% owned DPS joint venture and 50% owned DPTS Sand, LLC joint venture. All of the Company's equity investments had December 31 fiscal year-ends, and the Company recorded its 50% share of the joint ventures' net income or loss based on their most recent annual audited financial statements, if available, or unaudited financial statements if not significant, during the period the equity investments were accounted for using the equity method. The Company's share of the joint ventures' operating results for each period were adjusted for its share of intercompany transactions, which primarily related to rental agreements. Any significant unrealized intercompany profits or losses were eliminated in applying the equity method of accounting.
	Effective at the end of business on December 31, 2013, DPT was appointed the Facility Management Member of DPTS. The appointment as the Facility Management Member resulted in the consolidation of the accounts of DPTS with and into the consolidated financial statements of the Company as of December 31, 2014 and 2013. Accordingly, the accompanying December 31, 2013 consolidated balance sheet and the consolidated statements of operations for the year ended December 31, 2014 include the accounts and operations of DPTS. The operations of DPTS Sand, LLC commenced in June 2014, and the accompanying financial statements include its accounts and results of operations.
	At December 31, 2014, the Company has no investments in joint ventures where it has significant influence, representing equity ownership of not more than 50%, and is not accounting for any investments using the equity method.
	The Company followed applicable equity method authoritative guidance whereby declines in estimated investment fair value below carrying value assessed as other than temporary were recognized as a charge to earnings to reduce carrying value to estimated fair value. The Company periodically evaluated its equity investments for possible declines in value and determined if declines were other than temporary based on, among other factors, the sufficiency and outcome of equity investee performed impairment assessments (which includes third party appraisals and other analyses), the amount and length of time that fair value may have been below carrying value, near-term and longer-term operating and financial prospects of equity investees, and the Company's intent and ability to hold the equity investments for a period of time sufficient to allow for any anticipated recovery.
Cash And Cash Equivalents	Cash and Cash Equivalents
	The Company considers highly liquid investments with insignificant interest rate risk and original maturities of three months or less to be cash equivalents. Cash equivalents consist primarily of interest-bearing bank accounts and money market funds. The Company's cash positions represent assets held in checking and money market accounts. These assets are generally available to the Company on a daily or weekly basis and are highly liquid in nature. Due to the balances being greater than $250,000, the Company does not have FDIC coverage on the entire amount of bank deposits. The Company believes this risk of loss is minimal.
Accounts Receivable	Accounts Receivable
	Accounts receivable are carried on a gross basis, with no discounting. The Company regularly reviews all aged accounts receivable for collectability and establishes an allowance as necessary for individual customer balances. At December 31, 2014 there was no allowance for doubtful accounts.
Property And Equipment	Property and Equipment
	Property and equipment are recorded at cost and depreciated using the straight-line method over their estimated useful lives.
	Estimated useful lives are as follows:
	Site development		15years
	Terminal		13years
	Machinery		5 - 13 years
	Other Property and Equipment		3 - 5 years
	Land		—
	Expenditures for replacements, renewals, and betterments are capitalized. Maintenance and repairs are charged to operations as incurred. Depreciation expense was $4,332,900, $179,546 and $165,313 for the years ended December 31, 2014, 2013 and 2012, respectively. The Company had fixed assets related to in-progress construction of $1,886,470 and $7,551,187 at December 31, 2014 and 2013, respectively. The Company believes the estimated cost to complete construction is approximately $1.8 million. The projects associated with the fixed assets related to in-progress construction at December 31, 2014 and 2013 were undertaken by the joint ventures that funded all endeavors through equity from its members. The Company's policy is to capitalize interest when the construction time for a project is greater than one year.
Impairment	Impairment
	FASB Accounting Standards Codification ("ASC") 360-10-35-21 requires that long-lived assets to be held and used be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The determination of impairment is based upon expectations of undiscounted future cash flows, before interest, of the related asset. If the carrying value of the asset exceeds the undiscounted future cash flows, the impairment would be computed as the difference between the carrying value of the asset and the fair value. There was no impairment identified at December 31, 2014, 2013 and 2012.
Environmental Accrual	Environmental Accrual
	Accruals for estimated costs for environmental obligations generally are recognized no later than the date when the Company identifies what cleanup measures, if any, are likely to be required to address the environmental conditions. Included in such obligations are the estimated direct costs to investigate and address the conditions and the associated engineering, legal and consulting costs. In making these estimates, the Company considers information that is currently available, existing technology, enacted laws and regulations, and its estimates of the timing of the required remedial actions. Such accruals are initially measured on a discounted basis — and are adjusted as further information becomes available or circumstances change — and are accreted up over time. The Company has recorded no liability for environmental obligations as of December 31, 2014 and 2013.
Income Taxes	Income Taxes
	The Company accounts for income taxes under FASB ASC 740-10-30. Deferred income tax assets and liabilities are determined based upon differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. Accounting standards require the consideration of a valuation allowance for deferred tax assets if it is "more likely than not" that some component or all of the benefits of deferred tax assets will not be realized.
	The tax effects from an uncertain tax position can be recognized in the consolidated financial statements only if the position is more likely than not of being sustained if the position were to be challenged by a taxing authority. The Company has examined the tax positions taken in its tax returns and determined that there are no uncertain tax positions. As a result, the Company has recorded no uncertain tax liabilities in its consolidated balance sheet.
	The Company records Goodwill for income tax purposes for the amount that the purchase price paid for an asset or group of assets exceeds the fair value of the assets acquired. The Goodwill is amortized over fifteen years.
Stock-Based Compensation	Stock-Based Compensation
	The Company records expenses associated with the fair value of stock-based compensation. For fully vested and restricted stock grants, the Company calculates the stock-based compensation expense based upon estimated fair value on the date of grant. For stock warrants and options, the Company uses the Black-Scholes option valuation model to calculate stock-based compensation at the date of grant. Option pricing models require the input of highly subjective assumptions, including the expected price volatility. Changes in these assumptions can materially affect the fair value estimate.
Revenue Recognition	Revenue Recognition
	DPTS and DPTS Sand, LLC recognize revenues when the related services are performed, the sales price is fixed or determinable and collectability is reasonably assured. DPTS records the gross sale of fuel-related services when the transloading of petroleum-related products is complete. DPTS Sand, LLC records the gross sale when the transloading of sand-related products is complete.
Stock Issuance	Stock Issuance
	The Company records the stock-based compensation awards issued to non-employees and other external entities for goods and services at either the fair market value of the goods received or services rendered or the instruments issued in exchange for such services, whichever is more readily determinable, using the measurement date guidelines enumerated in FASB ASC 505-50-30.
Earnings Per Share	Earnings Per Share
	Basic earnings per share ("EPS") excludes dilution and is computed by dividing net income (loss) attributable to Company stockholders by the weighted average number of common shares outstanding during the period. Diluted EPS reflects the potential dilution that could occur if common stock equivalents were exercised or converted to common stock. The dilutive effect of common stock equivalents is calculated using the treasury stock method. When a loss from continuing operations exists, all potentially dilutive securities are anti-dilutive and therefore excluded from the computation of diluted EPS. As the Company had a loss for the years ended December 31, 2014, 2013, and 2012, the potentially dilutive shares are anti-dilutive and thus not added into the diluted EPS calculation.
	The following stock options, warrants and restricted stock represent potentially dilutive shares as of December 31, 2014, 2013 and 2012:
			December 31,
			2014		2013		2012
	Restricted Stock			1,031,150		769,063		568,437
	Stock Options			-		415,625		215,625
	Stock Warrants			2,771,000		2,771,000		2,671,000
	Total Potentially Dilutive Shares			3,802,150		3,955,688		3,455,062
Fair Value Measures	Fair Value Measures
	The Company measures fair value using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, essentially an exit price, based on the highest and best use of the asset or liability. The levels of the fair value hierarchy are:
		Level 1 – Quoted market prices in active markets that are accessible at measurement date for identical assets or liabilities;
		Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and
		Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities and less observable from objective sources.
Use Of Estimates	Use of Estimates
	The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Such significant estimates include recoverability of property and equipment, depreciable lives for property and equipment, fair value of the Operational Override liability, inputs in the valuation of certain equity transactions, and accounting for income taxes. Actual results may differ from those estimates.
Non-Controlling Interest	Non-Controlling Interest
	ASC 810 "Consolidation" requires that a non-controlling interest, previously referred to as a minority interest, be reported as part of equity in the consolidated financial statements and that losses be allocated to the non-controlling interest even when such allocation might result in a deficit balance, reducing the losses attributable to the controlling interest. The Company's non-controlling interest during the year ended December 31, 2014 is due to the non-controlling member of DPTS and DPTS Sand, LLC prior to the Company's purchase of the 50% interest owned by the non-controlling member.
