5. Income Per Common Share:

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

     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 shares of common stock which were outstanding for
     the three and nine month  periods  ended  September 30, 2005 and options to
     purchase 12,559 shares of common stock which were outstanding for the three
     and nine month  periods  ended  September 30, 2004 were not included in the
     computations  of diluted  earnings per share  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
     September  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
     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.

                                       8


     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.  ss. 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  September  30, 2005
     and December 31, 2004. A settlement agreement has not yet been finalized.

7. Dividends:

     On October 26, 2005,  the Company  declared a dividend of $.04 per share on
     its outstanding  Common Stock payable  November 21, 2005 to shareholders of
     record November 7, 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.  Refer to
     Note 2 for the potential impacts of the adoption of this standard.

     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). 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  principles.  SFAS
     No. 154 applies to all voluntary  changes in accounting  principles  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  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


                                       9


     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.

Nine Months Ended September 30, 2005 Compared to Nine Months
Ended September 30, 2004


Operating Revenues:

Operating revenues increased $1.1 million, or 5.8%, to $19.7 million in the nine
months ended September 30, 2005 from $18.6 million in 2004. This increase is the
combined result of a $749,000 (4.8%) increase in conventional  freight revenues,
a $208,000 (9.9%) increase in container  freight  revenues,  a $107,000  (21.2%)
increase in other  freight  related  revenues and a $17,000  (3.5%)  increase in
other operating revenues.

The increase in conventional  freight  revenues  results from a 2.2% increase in
the average revenue received per conventional  carloading and a 2.6% increase in
traffic  volume.  The  Company's  conventional  carloadings  increased by 637 to
24,946 in the first nine  months of 2005 from  24,309 in 2004.  Rate  increases,
including  diesel  fuel  surcharges,  account  for the  increase  in the average
revenue per carloading.

The  increase in  container  revenues  is the result of a 16.7%  increase in the
average revenue  received per container  partially  offset by a 5.8% decrease in
the volume of  containers  handled.  Intermodal  containers  handled  during the
nine-month  period decreased by 2,841 to 46,426 in 2005 from 49,267 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 revenues results from increased  demurrage charges
billed to freight  customers.  This revenue  partially offsets the increased car
hire expense incurred during the nine-month period.

                                       12


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


Other Income:

Other  income  decreased  by  $940,000  to  $492,000  in the nine  months  ended
September  30, 2005 from $1.4 million in 2004.  Other income in 2004  includes a
gain of $948,000  realized  on the  disposal of a portion of a branch line which
the Commonwealth of Massachusetts acquired by eminent domain.

Operating Expenses:

Operating  expenses  increased by $754,000,  or $4.1%,  to $19.1  million in the
nine months  ended  September 30, 2005 from $18.4  million in 2004.  Diesel fuel
expense  for the  period  increased  by  $582,000  reflecting  the high  cost of
petroleum  products.  Car hire expense  increased by $232,000 during the period,
which costs were partially offset by increased  demurrage billings as previously
discussed.  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 September 30, 2005 Compared to Three Months
Ended September 30, 2004

Operating Revenues:

Operating  revenues  increased  $413,000,  or 5.9%, to $7.4 million in the third
quarter of 2005 from $7.0 million in the third quarter of 2004. This increase is
the net result of a $416,000 (7.1%) increase in  conventional  freight  revenues
and a $68,000 (8.2%) increase in container freight revenues  partially offset by
a $14,000  (7.6%)  decrease  in other  freight  related  revenues  and a $57,000
(42.2%) decrease in other operating revenues.

The increase in conventional  freight  revenues  results from a 5.6% increase in
conventional  traffic volume and a 1.5% increase in the average revenue received
per conventional carloading. The Company's conventional carloadings increased by
550 to 10,449 in the third  quarter of 2005 from 9,899 in 2004,  The increase in
the average  revenue  received  per  conventional  carloading  results from rate
increases, including diesel fuel surcharges.

The increase in container freight revenues is the net result of a 25.8% increase
in average revenue  received per container  partially offset by a 14.0% decrease
in the volume of containers  handled.  Intermodal  containers handled during the
third  quarter of 2005  decreased  by 2,739 to 16,813  from  19,552 in the third
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 toward higher rated containers.

The small decrease in other freight related revenues is attributable to declines
in billings for secondary switching, weighing and other ancillary services which
more than offset increased demurrage billings.

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

                                       13


Other Income:

Other income  decreased by $1.0 million to $133,000 in the third quarter of 2005
from $1.2 million in the third quarter of 2004. As previously  noted,  the third
quarter of 2004  includes a gain of $948,000  which the Company  realized when a
portion  of  one  of  its  branch  lines  was  taken  by  the   Commonwealth  of
Massachusetts by eminent domain.

Operating Expenses:

Operating expenses for the third quarter of 2005 increased by $282,000, or 4.6%,
to $6.5  million from $6.2  million in the third  quarter of 2004.  Increases in
diesel fuel costs of $264,000,  as  previously  discussed,  accounts for most of
this increase.


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

During the first nine months of 2005 the Company  generated $2.5 million of cash
from its operations.  Total cash and  equivalents  decreased by $740,000 for the
period.  The  principal  utilization  of cash during the period,  other than for
operations,  was for  expenditures  for  property and  equipment,  of which $1.7
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  working  capital,
capital expenditure and dividend requirements through the end of the year.

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 September 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 which expires May 31,
2007  provides for  borrowings  which bear  interest at variable  rates based on
either the 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 September 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.

                                       14



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.  Based upon that  evaluation,  the Chief  Executive  Officer  and the
Treasurer  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 affect, the Company's internal
control over financial reporting.
