                                EXPLANATORY NOTE

This Amendment No. 1 on Form 10-K/A ("Amendment No. 1") amends the Annual Report
on Form 10-K of Providence and Worcester  Railroad  Company (the  "Company") for
the fiscal year ended December 31, 2008,  filed with the Securities and Exchange
Commission ("SEC") on March 25, 2009 (the "Original 10-K"). This Amendment No. 1
is being filed for the sole purpose of correcting the certifications required by
Rules  13a-15(e) and 15d-15(e) of the Exchange Act of 1934, as adopted  pursuant
to   Section   302   of   the    Sarbanes-Oxley    Act   of   2002   (the   "302
Certifications"),certain provisions of which were inadvertently omitted when the
Original 10-K was filed. The amended 302 Certifications are being filed in their
entirety as Exhibits 31.1 and 31.2 to this Amendment No. 1.

Except  as  described  above,  this  Amendment  No. 1 does not  amend  any other
information  set forth in the  Original  10-K and the  Company  has not  updated
disclosures  included therein to reflect any events that occurred  subsequent to
the date of the Original 10-K. Accordingly,  this Amendment No. 1 should be read
in  conjunction  with the Original 10-K and the Company's  filings made with the
SEC  subsequent to the filing of the Original 10-K. The filing of this Amendment
No. 1 shall  not be deemed an  admission  that the  Original  10-K,  when  made,
included any untrue  statement of a material fact or omitted to state a material
fact necessary to make a statement not misleading.

information included in this report, fairly present in all material respects the
financial  condition,  results of operations and cash flows of the registrant as

     4. The registrant's  other certifying  officer(s) and I are responsible for

     a.   Designed  such  disclosure  controls  and  procedures,  or caused such
          disclosure   controls  and   procedures  to  be  designed   under  our
          supervision,  to ensure  that  material  information  relating  to the

          reliability  of financial  reporting and the  preparation of financial
          statements for external purposes in accordance with generally accepted
          accounting principles;

     c.   Evaluated the  effectiveness of the registrant's  disclosure  controls
          and procedures and presented in this report our conclusions  about the
          effectiveness of the disclosure controls and procedures, as of the end
          of the period covered by this report based on such evaluation; and

     d.   Disclosed  in this  report  any  change in the  registrant's  internal
          control over financial reporting that occurred during the registrant's
          most recent fiscal quarter (the registrant's  fourth fiscal quarter in
          the case of an annual  report)  that has  materially  affected,  or is
          reasonably  likely to materially  affect,  the  registrant's  internal
          control over financial reporting; and

     5. The registrant's other certifying officer(s) and I have disclosed, based
on our most recent evaluation of internal control over financial  reporting,  to
the registrant's  auditors and the audit committee of the registrant's  board of
directors (or persons performing the equivalent functions):

     a.   All significant  deficiencies and material weaknesses in the design or
          operation  of internal  control  over  financial  reporting  which are
          reasonably  likely to  adversely  affect the  registrant's  ability to
          record, process, summarize and report financial information; and

     b.   Any fraud, whether or not material,  that involves management or other
          employees who have a  significant  role in the  registrant's  internal
          control over financial reporting.
