Earnings Per Share [Abstract]	'
Loss per Common Share	'
	5	Loss per Common Share:
	Loss per common share is computed using the weighted average number of common shares outstanding during each quarter. Diluted income (loss) per common share reflects the effect of the Company’s outstanding convertible preferred stock (using the if-converted method) and options (using the treasury stock method), except where such items would be anti-dilutive.
	A reconciliation of weighted average shares used for the basic computation and that used for the diluted computation is as follows:
			2014								2013
			Net Loss			Shares		Per Share			Net Loss			Shares		Per Share
								Amount								Amount
	Basic Earnings per Share
	Net Loss available to Common Shareholders		$	(680	)						$	(1,094	)
	Basic loss per share		$	(680	)		4,851	$	(.14	)	$	(1,094	)		4,842	$	(.23	)
	Diluted Earnings per Share
	Net Loss available to Common Shareholders		$	(680	)						$	(1,094	)
	Effect of Dilutive Securities						—								—
	Diluted loss per Share		$	(680	)		4,851	$	(.14	)	$	(1,094	)		4,842	$	(.23	)
	Options to purchase 67,695 and 70,348 shares of common stock were outstanding at March 31, 2014 and 2013, respectively. No outstanding options were included in the computation of diluted (loss) earnings per common share for 2014 and 2013 as the effect would be antidilutive. Shares of preferred stock convertible into 64,000 shares of common stock were outstanding at March 31, 2014 and 2013. These shares were not included in the computation of diluted (loss) earnings per common share for 2014 and 2013 because of the anti-dilutive effect.

Commitments And Contingencies Disclosure [Abstract]	'
Commitments and Contingent Liabilities	'
	6	Commitments and Contingent Liabilities:
	The Company is a defendant in certain lawsuits relating to casualty losses, many of which are covered by insurance subject to a deductible. The Company believes that adequate provision has been made in the condensed financial statements for any expected liabilities which may result from disposition of such lawsuits.
	On January 29, 2002, the Company received a “Notice of Potential Liability” from the United States Environmental Protection Agency (“EPA”) regarding an existing Superfund Site that includes the J.M. Mills Landfill in Cumberland, Rhode Island. EPA sends these “Notice” letters to potentially responsible parties (“PRPs”) under the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”). EPA identified the Company as a PRP based on its status as an owner and/or operator because its railroad property traverses the Site. Via these Notice letters, EPA makes a demand for payment of past costs (identified in the letter as $762) and future costs associated with the response actions taken to address the contamination at the Site, and requests PRPs to indicate their willingness to participate and resolve their potential liability at the Site. The Company has responded to EPA by stating that it does not believe it has any liability for this Site, but that it is interested in cooperating with EPA to address issues concerning liability at the Site. At this point, two other parties have already committed via a consent order with EPA to pay for the Remedial Investigation/Feasibility Study (“RI/FS”) phase of the clean-up at the Site, which will take approximately two or more years to complete. After that, EPA will likely seek to negotiate the cost of the Remedial Design and implementation of the remedy at the Site with the PRPs it has identified via these Notice letters (which presently includes over sixty parties, and is likely to increase after EPA completes its investigation of the identity of PRPs). On December 15, 2003, the EPA issued a second “Notice of Potential Liability” letter to the Company regarding the Site. EPA again identified the Company as a PRP, this time because EPA “believes that [the Company] accepted hazardous substance for transport to disposal or treatment facilities and selected the site for disposal.” The Company responded again to EPA stating that it is interested in cooperating with EPA but that it does not believe it has engaged in any activities that caused contamination at the Site. The Company believes that none of its activities caused contamination at the Site, and will contest this claim by EPA and, therefore, no liability has been accrued for this matter.
	In connection with the EPA claim described above, the two parties who have committed to conduct the RI/FS at the Site filed a complaint in the U.S. District Court of Rhode Island against the Company, in an action entitled CCL Custom Manufacturing, Inc. v. Arkwright Incorporated, et al (consolidated with Unilever Bestfoods v. American Steel & Aluminum Corp. et al), C.A. No. 01-496/L, on December 18, 2002. The Company was one of about sixty parties named by Plaintiffs, in this suit, to recover response costs incurred in investigating and responding to the releases of hazardous substances at the Site. Plaintiffs alleged that the Company is liable under 42 U.S.C. § 961(a)(3) of CERCLA as an “arranger” or “generator” of waste that ended up at the Site. The Company entered into a Generator Cooperation Agreement with other defendants to allocate costs in responding to this suit, and to share technical costs and information in evaluating the Plaintiffs’ claims. Although the Company does not believe it generated any waste that ended up at this Site, or that its activities caused contamination at the Site, the Company paid $45 to settle this suit in March 2006.

Amtrak Agreement	'
	7	Amtrak Agreement
	On April 4, 2012, the Company and National Railroad Passenger Corporation (“Amtrak”) entered into the 2012 Settlement and Amendment Agreement (the “2012 Agreement”) which settles certain disputes between the parties and amends, in part, both an Agreement dated January 3, 1978 (the “1978 Agreement”) and an Agreement dated July 9, 1979 by and between Amtrak and the Company. Under the 1978 Agreement, Amtrak obtained the right to remove certain Company trackage subject to the requirement of providing replacement facilities.
	Pursuant to the Agreement, the Company received a credit for mileage travelled along the Northeast Corridor. The Company will recognize the expense offset relative to Track Usage Fees as the expenses are incurred. As such, the Company did not record any related assets or liabilities relative to the mileage credit. The Company has recorded the following offsets to Track Usage expense and has the following track mileage credit remaining:

	8	Related Party Transaction:
	Robert Eder, who owns a majority of the Company’s Preferred Shares, with his wife, also controls Capital Properties, Inc. (“CPI”) and its subsidiaries. Pursuant to an agreement between the Company and Getty Oil Company (Eastern Operations), Inc. dated August 6, 1975, the Company has the right to relocate any portion of two pipelines located within the Company’s right of way, in East Providence, Rhode Island. The Company and CPI have supported an extension of Waterfront Drive in East Providence along the Company’s right of way which was completed in the fall of 2012. The State of Rhode Island’s plans for Waterfront Drive’s extension required a relocation of a portion of the pipelines which the Company has the right to relocate. The Rhode Island Department of Transportation (“RIDOT”) entered into an agreement with the Company to reimburse the Company for expenses incurred by us in relocating the pipelines up to a maximum of $159. In May, 2011 CPI’s subsidiary, Capital Terminal Company (“CTC”), entered into an agreement with the Company to act as the Company’s agent to select, direct and supervise all subcontractors subject to the Company’s approval. All invoices from contractors to CTC are submitted to the Company for approval along with a check from CTC in the amount of the invoice. The Company pays the invoice out of the funds provided by CTC. The Company is then obligated to submit the invoices to RIDOT for reimbursement under its agreement with RIDOT. When the Company receives reimbursement from RIDOT, it is obligated to pay that amount to CTC. Any shortfall in RIDOT’s reimbursement is borne by CTC. At March 31, 2014 and December 31, 2013, respectively, the remaining receivable in the amount of $22 from RIDOT, and the corresponding accounts payable to CTC have been reflected in the Company’s Condensed Balance Sheets.
	In May 2012 the Company and CPI entered into a License Agreement licensing to CPI track facilities which may be installed in connection with a railcar-loading/unloading facility up the Company’s right-of-way in East Providence, Rhode Island. The License Agreement continues through December 31, 2015, and may be extended for additional three-year periods unless cancelled by CPI upon 30-days written notice prior to termination.
