5.   Income (Loss) per Common Share:

     Basic income (loss) per common share is computed using the weighted-average
     number of common  shares  outstanding  during each period.  Diluted  income
     (loss) per common share  reflects the effect of the  Company's  outstanding
     convertible  preferred stock,  options and warrants except where such items
     would be antidilutive.

                                       7


     A reconciliation of weighted-average  shares used for the basic computation
     and that used for the diluted computation is as follows:

     Options  to  purchase   5,394  and  12,559  shares  of  common  stock  were
     outstanding  for the  three-month  periods  ended  June 30,  2005 and 2004,
     respectively,  but were not included in the computation of income per share
     because their effect would be antidilutive.

     Preferred  stock  convertible  into  64,500  shares  of  common  stock  was
     outstanding  for the  six-month  periods  ended June 30,  2005 and 2004 and
     options  to  purchase  51,011  and  56,854  shares  of  common  stock  were
     outstanding  for the six-  month  periods  ended  June 30,  2005 and  2004,
     respectively.  These  common  stock  equivalents  were not  included in the
     computation  of the diluted loss per share for these periods  because their
     effect would be antidilutive.

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,  in the total amount of $470 as of June
     30,  2005,  has been  made in the  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  Superfund  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). 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.

     On  December  15,  2003,  the EPA  issued a  second  "Notice  of  Potential
     Liability"  letter to the Company  regarding the Site. EPA again identified


                                       8


     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.

     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 is one of about
     sixty parties named thus far by  Plaintiffs,  who seek to recover  response
     costs incurred in investigating and responding to the releases of hazardous
     substances at the Site.  Plaintiffs allege that the Company is liable under
     42 U.S.C.  section  961(a)(3) of CERCLA as an "arranger" or  "generator" of
     waste that ended up at the Site.  The Company has 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 has agreed to settle this suit for
     $45 and has accrued a liability  for this amount as of December 31, 2004. A
     settlement agreement has not yet been finalized.

7.   Dividends:

     On July 27, 2005, the Company  declared a dividend of $.04 per share on its
     outstanding  Common Stock payable August 22, 2005 to shareholders of record
     August 8, 2005.

8.   Recent Accounting Pronouncements:

     On December 16,  2004,  the  Financial  Accounting  Standards  Board issued
     Statement of Financial Accounting Standards No. 123R, "Share-Based Payment"
     (SFAS No. 123R). This Statement is a revision of SFAS No. 123,  "Accounting
     for Stock-Based  Compensation",  and supersedes Accounting Principles Board
     Opinion No. 25, "Accounting for Stock Issued to Employees", and its related
     implementation  guidance. SFAS No. 123R focuses primarily on accounting for
     transactions  in which an entity obtains  employee  services in share-based
     payment  transactions.  The Statement  requires entities to recognize stock
     compensation expense for awards of equity instruments to employees based on
     the  grant-date  fair value of those awards (with limited  exceptions).  On
     April 14, 2005 the Securities and Exchange  Commission issued a revision to
     SFAS No. 123R and the effective date for this pronouncement will be for the
     first  annual  reporting  period that begins  after June 15,  2005.  We are
     evaluating  the two  methods  of  adoption  allowed by SFAS No.  123R:  the
     modified-  prospective  transition  method  and the  modified-retrospective
     transition method.


     In  May 2005,  the  Financial  Accounting  Standards  Board  (FASB)  issued
     Statement of Financial  Accounting  Standards No. 154,  "Accounting Changes
     and  Error  Corrections"  (SFAS  No. 154;  the  Statement).  SFAS  No. 154,
     effective  for  interim  or  annual  reporting   periods   beginning  after
     December 15,  2005, replaces APB Opinion No. 20,  "Accounting Changes", and
     FASB Statement No. 3,  "Reporting  Accounting  Changes in Interim Financial
     Statements",  and changes the requirements for and reporting of a change in
     accounting  principle.  The Statement  applies to all voluntary  changes in
     accounting   principle   and  to  changes   required   by  new   accounting
     pronouncements  that do not include  specific  transition  provisions,  and
     requires  retrospective  application of changes in accounting principles to
     prior periods financial  statements unless it is impracticable to determine
     either the  period-specific  or  cumulative  effects of the change.  In the
     event of a change in accounting principle, accounting estimate or reporting


                                       9


     entity,  we will  describe  the nature of the change and the reason for the
     change,  and will reflect the impact of the change in the current and prior
     period financial statements as appropriate.

     In March 2005, the Financial  Accounting Standards Board (FASB) issued FASB
     Interpretation   No. 47,   "Accounting  for  Conditional  Asset  Retirement
     Obligations - an interpretation of FASB Statement No. 143" (FIN 47). FIN 47
     clarifies the term conditional asset retirement  obligation as used in SFAS
     No. 143,  "Accounting for Asset  Retirement  Obligations,"  and requires an
     entity to recognize a liability for the fair value of a  conditional  asset
     retirement  obligation if the fair value can be reasonably  estimated.  Any
     uncertainty  about the amount and/or  timing of the future  settlement of a
     conditional  asset  retirement  obligation  should  be  factored  into  the
     measurement of the liability when  sufficient  information  exists.  FIN 47
     also  clarifies  when  an  entity  would  have  sufficient  information  to
     reasonably  estimate  the fair  value of an  asset  retirement  obligation.
     FIN 47 is effective for fiscal years ending after  December 15,  2005.  The
     Company is  currently  determining  the  impact of FIN 47 on its  financial
     reporting and disclosures.

PROVIDENCE AND WORCESTER RAILROAD COMPANY

ITEM 2-MANAGEMENT'S DISCUSSION AND ANALYSIS OF
- ----------------------------------------------
      FINANCIAL CONDITION AND RESULTS OF OPERATIONS
      ---------------------------------------------

The statements  contained in  Management's  Discussion and Analysis of Financial
Condition  and  Results  of  Operations  ("MDA")  which are not  historical  are
"forward-looking statements" within the meaning of Section 27A of the Securities
Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934,
as amended.  These  forward-looking  statements  represent the Company's present
expectations or beliefs concerning future events. The Company cautions, however,
that actual results could differ materially from those indicated in MDA.


Critical Accounting Policies
- ----------------------------

The Securities  and Exchange  Commission  ("SEC")  defines  critical  accounting
policies as those that  require  application  of  management's  most  difficult,
subjective or complex judgments, often as a result of the need to make estimates
about the  effect of matters  that are  inherently  uncertain  and may change in
subsequent periods.

The  Company's  significant  accounting  policies are described in Note 1 of the
Notes to  Financial  Statements  in its Annual  Report on Form 10-K.  Not all of
these  significant  accounting  policies  require  management to make difficult,
subjective  or complex  judgments or  estimates.  Management  believes  that the
Company's policy for the evaluation of long-lived asset impairment is a critical
accounting policy.

The  Company  evaluates  long-lived  assets for  impairment  whenever  events or
changes in  circumstances  indicate that the carrying amount of an asset may not
be  recoverable.  When factors  indicate  that assets  should be  evaluated  for
possible  impairment,  the Company uses an estimate of the related  undiscounted
future cash flows over the  remaining  lives of the assets in measuring  whether
the carrying amounts of the assets are recoverable.

Six Months Ended June 30, 2005 Compared to Six Months Ended June 30, 2004


Operating Revenues:

Operating  revenues  increased  $668,000,  or 5.8%,  to $12.2 million in the six
months  ended June 30,  2005 from $11.6  million in 2004.  This  increase is the
combined result of a $333,000 (3.4%) increase in conventional  freight revenues,
a $140,000 (11.1%) increase in container  freight  revenues,  a $121,000 (37.8%)
increase in other freight  related  revenues and a $74,000  (25.3%)  increase in
other operating revenues.

The increase in conventional  freight  revenues  results from a 2.8% increase in
the average  revenue  received  per  conventional  carloading  and a small (.6%)
increase in traffic volume. The Company's conventional  carloadings increased by
87 to  14,497  in the  first  six  months  of 2005  from  14,410  in 2004.  Rate
increases, including diesel fuel surcharges, largely account for the increase in
the average revenue per carloading.

The increase in container freight revenues is the result of an 11.5% increase in
the average revenue received per container  slightly offset by a .3% decrease in
the volume of  containers  handled.  Intermodal  containers  handled  during the
six-month  period  decreased  by 102 to 29,613 in 2005 from 29,715 in 2004.  The
increase in the average  revenue  received  per  container  is  attributable  to
contractual  rate  adjustments,  as  well as a  shift  in the mix of  containers
handled.

The increase in other freight related revenues results from increased  demurrage
charges  billed  to  freight  customers.  This  revenue  partially  offsets  the
increased car hire expense incurred during the period.

                                       12


The  increase  in other  operating  revenues  results  from  higher  maintenance
department billings.  Revenues of this type vary from period to period depending
upon the needs of freight customers and other outside parties.

Operating Expenses:

Operating expenses increased by $472,000, or 3.9%, to $12.6 million in 2005 from
$12.2 million in 2004.  Diesel fuel costs for the six-month  period increased by
$318,000  reflecting  the higher  prices paid for petroleum  products.  Car hire
expense  increased  by  $197,000  during the  period.  These  higher  costs were
partially  offset by  increased  demurrage  billings  to  freight  customers  as
previously noted.  Casualties and insurance expense in 2004 includes a provision
of $275,000 to cover a lawsuit  judgment  against the Company which was rendered
in May 2004 and subsequently settled in full in December 2004 for $208,000.


Three Months Ended June 30, 2005 Compared to Three Months Ended June 30, 2004

Operating Revenues:

Operating  revenues  increased  $95,000,  or 1.5% to $6.6  million in the second
quarter of 2005 from $6.5 million in the second  quarter of 2004.  This increase
is the net result of a $67,000 (1.2%) increase in conventional freight revenues,
a $38,000  (5.8%)  increase in container  freight  revenues and a $14,000 (8.4%)
increase in other freight related revenues partially offset by a $24,000 (12.8%)
decrease in other operating revenues.

The increase in  conventional  freight  revenues  results from 1.1%  increase in
conventional traffic volume and .1% increase in the average revenue received per
conventional carloading. The Company's conventional carloadings increased by 102
to 9,211 in the  second  quarter  of 2005  from  9,109  in  2004.  Increases  in
construction aggregate and coal traffic (lower-rated commodities) were partially
offset by  decreases  in  carloadings  of higher  rated  commodities.  The small
increase in the average revenue  received per  conventional  carloading  results
from modest rate increases,  including diesel fuel surcharges, largely offset by
the effects of the changes in traffic mix as previously discussed.

The increase in container freight revenues is the net result of a 15.9% increase
in the  average  revenue  received  per  container  partially  offset by an 8.7%
decrease in the volume of  containers  handled.  Intermodal  containers  handled
during the second  quarter of 2005  decreased  by 1,362 to 14,263 from 15,625 in
the second  quarter of 2004.  The increase in the average  revenue  received per
container is attributable to contractual rate adjustments, as well as a shift in
the mix of containers handled.  Lower rated containers accounted for much of the
decline in volume.

The increase in other freight related revenues results from increased  demurrage
charges billed to freight customers as previously discussed.

The decrease in other operating revenues results from a reduction in maintenance
department billings to freight customers and other outside parties.

Operating Expenses:

Operating  expenses for the second  quarter of 2005  increased  by $142,000,  or
2.3%,  from the  second  quarter  of 2004.  Increases  in diesel  fuel  costs of
$218,000 and car hire expense of $55,000 during 2005 were offset by the $275,000
lawsuit provision which was included in 2004.

Liquidity and Capital Resources
- -------------------------------

During the first six months of 2005 the Company  generated  $1.1 million of cash
from its operations.  Total cash and  equivalents  decreased by $1.2 million for
the period. The principal  utilization of cash during the period, other than for
operations,  was for  expenditures  for  property and  equipment,  of which $1.1
million was for  additions  and  improvements  to track  structure,  and for the
payment of dividends.

In management's  opinion, cash generated from operations during the remainder of
2005 will be sufficient to enable the Company to meet its operating expenses and
capital expenditure and dividend requirements.

Seasonality
- -----------

Historically,  the Company's operating revenues are lowest for the first quarter
due to the absence of construction  aggregate shipments during a portion of this
period and to winter weather conditions.

Item 3. Quantitative and Qualitative Disclosures About Market Risk
- ------------------------------------------------------------------

Cash and Equivalents

As of June 30,  2005,  the Company is exposed to market  risks  which  primarily
include changes in U.S. interest rates.

The  Company  invests  cash  balances  in excess of  operating  requirements  in
short-term  securities,  generally  with  maturities  of 90  days  or  less.  In
addition,  the  Company's  revolving  line  of  credit  agreement  provides  for
borrowings  which bear interest at variable  rates based on either prime rate or
one and one half  percent  over either the one or three month  London  Interbank
Offered  Rates.  The  Company  had no  borrowings  outstanding  pursuant  to the
revolving line of credit  agreement at June 30, 2005. The Company  believes that
the effect, if any, of reasonably  possible  near-term changes in interest rates
on the  Company's  financial  position,  results of  operations,  and cash flows
should not be material.

Item 4. Controls and Procedures
- -------------------------------

As required by Rule 13a-15 under the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), the Company carried out an evaluation of the effectiveness
of the design and operation of the Company's  disclosure controls and procedures
as of the end of the period covered by this report.  This evaluation was carried
out  under  the  supervision  and  with  the   participation  of  the  Company's
management,  including the Company's Chief  Executive  Officer and the Company's
Treasurer and Chief Financial  Officer.  Based upon that  evaluation,  the Chief
Executive  Officer and the Treasurer and Chief Financial  Officer concluded that
the Company's  disclosure  controls and  procedures are effective to ensure that
information  required to be disclosed by the Company in reports that it files or
submits under the Exchange Act is recorded,  processed,  summarized and reported
within the time periods  specified  in the  Securities  and Exchange  Commission
rules and forms.

There was no significant change in the Company's internal control over financial
reporting that occurred during the Company's most recent fiscal quarter that has
materially affected, or is reasonably likely to materially affect, the Company's
internal control over financial reporting.
