                    PROVIDENCE AND WORCESTER RAILROAD COMPANY

                    NOTES TO FINANCIAL STATEMENTS (Unaudited)

                     SIX MONTHS ENDED JUNE 30, 2006 AND 2005
                 (Dollars in Thousands Except Per Share Amounts)

1.   In the opinion of management, the accompanying interim financial statements
     contain all adjustments (consisting solely of normal recurring adjustments)
     necessary to present fairly the financial  position as of June 30, 2006 and
     the results of operations and cash flows for the interim periods ended June
     30,  2006 and 2005.  Results for interim  periods  may not  necessarily  be
     indicative  of the  results  to be  expected  for the year.  These  interim
     financial  statements  should  be read in  conjunction  with the  Company's
     Annual Report on Form 10-K for the year ended  December 31, 2005 filed with
     the Securities and Exchange Commission.

2.   Stock-Based Compensation:

     Effective  January 1, 2006,  the Company  adopted  Statement  of  Financial
     Accounting Standards No. 123(R),  "Share-Based  Payment," (SFAS No. 123(R))
     using the modified  prospective method. This method requires that companies
     recognize compensation expense for new stock option grants and the unvested
     portion of prior stock option  grants at their fair value on the grant date
     and  recognize  this expense over the requisite  service  period for awards
     expected to vest.  All of the  Company's  stock  options  granted  prior to
     January 1, 2006 were 100%  vested and as a result did not impact the amount
     of expense recorded during the three- and six-month  periods ended June 30,
     2006.  The  results for prior year  periods  have not been  restated.  As a
     result of  adopting  SFAS No.  123(R),  stock-based  employee  compensation
     expense,  net of  income  taxes,  in the  amount  of $14 and $28,  has been
     charged  against  income in the three- and six month periods ended June 30,
     2006,  respectively,  for stock options  granted during these periods.  The
     Company's  policy  is to  estimate  the fair  market  value of each  option
     granted on the date of grant using the  Black-Scholes  option pricing model
     and record the compensation  expense on a straight-line basis over the year
     in which the grant was made. The Company issues new common stock to satisfy
     stock options  exercised.  Key assumptions used to apply the  Black-Scholes
     option pricing model are set forth below:

     Average risk-free interest rate                                  4.32%
     Expected life of option grants                                   7.0 years
     Expected volatility of underlying stock                         88.28%
     Expected dividend payment rate, as a percentage of the
      share price on the date of grant                               1.07%

     The following table illustrates the effect on the net loss and net loss per
     share for the  three-month  and six month periods ended June 30, 2005 as if
     the fair value based method of SFAS No. 123,  "Accounting  for  Stock-Based
     Compensation,"  had been  applied  for all  outstanding  awards for periods
     prior to the adoption of SFAS No. 123(R).

     At June 30, 2006, the Company had one stock option plan,  the  Nonqualified
     Stock Option Plan.  Under the plan,  options to purchase  common stock were
     granted to officers,  directors and management employees at prices not less
     than the fair  market  value of the common  stock on the date of the grant.
     The  options  expire ten years from the grant  date.  As of June 30,  2006,
     there were 226,368 shares available for stock option grants under the plan.

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 and stock options except where such items would
     be antidilutive.

                                       8


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

     Options to purchase 5,029 and 5,394 shares of common stock were outstanding
     for the three-month periods ended June 30, 2006 and 2005, 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  period  ended June 30, 2005 and options to
     purchase 5,029 and 51,011 shares of common stock were  outstanding  for the
     six-month periods ended June 30, 2006 and 2005, respectively.  These common
     stock  equivalents  were not  included  in the  computation  of the diluted
     income  (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 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


                                       9


     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.

     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  paid $45 to settle  this suit in
     March 2006.

7.   Dividends:

     On July 26, 2006, the Company  declared a dividend of $.04 per share on its
     outstanding  Common Stock payable August 21, 2006 to shareholders of record
     August 7, 2006.

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, 2006 Compared to Six Months Ended June 30, 2005


Operating Revenues:

Operating revenues increased $1.6 million, or 13.3%, to $13.8 million in the six
months ended June 30, 2006 from $12.2 million in 2005.  This increase is the net
result of a $1.4 million (13.8%) increase in conventional freight revenues and a
$312,000 (22.3%) increase in container freight revenues offset to a small extent
by a $53,000  decrease in other freight related revenues and an $18,000 decrease
in other operating revenues.

The increase in conventional freight revenues is attributable to a 9.8% increase
in traffic  volume and a 3.6%  increase  in the  average  revenue  received  per
conventional  carloading.  The Company's  conventional  carloadings increased by
1,419 to  15,917 in the first  six  months  of 2006  from  14,498 in 2005.  Rate
increases,  including diesel fuel  surcharges,  as well as changes in the mix of
commodities account for the increase in the average revenue per carloading.

The increase in container  freight  revenues is the combined  result of an 18.0%
increase  in the average  revenue  received  per  container  and a 3.6%  percent
increase in container traffic volume.  Intermodal  containers handled during the
six-month  period  increased by 1,078 to 30,691 in 2006 from 29,613 in 2005. The
increase in the average  revenue  received  per  container  is  attributable  to


                                       12


contractual rate adjustments based upon railroad industry cost indices,  as well
as a  continuing  shift in the mix of  containers  handled  toward  higher rated
containers.

The decrease in other  freight  related  revenues is the result of a decrease in
demurrage  charges  incurred  by freight  customers  and the  decrease  in other
operating  revenues  is the  result of lower  maintenance  department  billings.
Revenues of these types vary from period to period  depending  upon the needs of
freight and other customers.

Operating Expenses:

Operating expenses increased by $1.6 million,  or 12.5%, to $14.2 million during
the six months  ended  June 30,  2006 from $12.6  million in 2005.  Diesel  fuel
expense  for  the  six-month  period  increased  by  $391,000  as  a  result  of
significant  increases in the cost of petroleum  products.  Employee  health and
welfare costs increased by $383,000 between periods. This is largely a one- time
cost relating to changes in employee health insurance plans implemented in 2006.
The  increase in  expenditures  for  purchased  services of $465,000 was largely
offset by grant proceeds resulting in increased cost recoveries.


Three Months Ended June 30, 2006 Compared to Three Months Ended June 30, 2005

Operating Revenues:

Operating  revenues increased  $655,000,  or 9.9%, to $7.2 million in the second
quarter of 2006 from $6.6 million in the second  quarter of 2005.  This increase
is the net result of a $542,000 (9.8%) increase in conventional freight revenues
and a $180,000 (26.0%) increase in container  freight revenues offset to a small
extent by a $57,000  decrease in other  freight-related  revenues  and a $10,000
decrease in other operating revenues.

The increase in conventional freight revenues for the quarter is attributable to
an 8.2% increase in the average revenue received per conventional carloading and
a 1.5%  increase  in traffic  volume.  The  Company's  conventional  carloadings
increased by 136 to 9,348 in the second quarter of 2006 from 9,212 in the second
quarter of 2005. The increase in the average  revenue per carloading  during the
quarter  results  from a  change  in the mix in  traffic  towards  higher  rated
commodities, as well as rate increases, including diesel fuel surcharges.

The  increase in  container  freight  revenues  for the quarter is the  combined
result of a 16.0% increase in the average revenue  received per container and an
8.7% increase in container traffic volume.  Intermodal containers handled during
the  quarter  increased  by 1,236 to  15,499 in 2006  from  14,263 in 2005.  The
increase in the average  revenue  received  per  container  is  attributable  to
contractual rate adjustments and to a shift in the mix of containers handled, as
previously discussed.

The  decrease  in other  freight  related  revenues  results  from a decrease in
demurrage charges to freight customers.  The decline in other operating revenues
is attributable to a lower level of maintenance  department  billings to outside
parties

Operating Expenses:

Operating expenses increased by $617,000, or 9.6%, to $7.1 million in the second
quarter of 2006 from $6.4  million in 2005.  Increased  diesel fuel and employee
health and welfare costs, as previously  discussed,  accounted for approximately
$250,000 of this increase.

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

During the first six months of 2006 the Company generated  $879,000 of cash from
its operations.  Total cash and cash  equivalents  decreased by $436,000 for the
period.  The  principal  utilization  of cash during the period,  other than for
operations,  was for expenditures for property and equipment and for the payment
of dividends.

In management's  opinion, cash generated from operations during the remainder of
2006 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,  2006,  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, 2006. 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.

                                  ARTICLE. III

     Section 2.  Vacancies in the Board of Directors may be filled in the manner
provided in the charter.  A vacancy or vacancies shall be deemed to exist at any
time the  number of  directors  then in  office is less than the whole  Board as

But in the case of necessity,  such notice may be given at such time and in such
manner as the President or the Chairman may direct.
