                                EXPLANATORY NOTE

This  Amendment  No. 1 on Form 10-Q/A  ("Amendment  No. 1") amends the Quarterly
Report on Form 10-Q of Providence and Worcester Railroad Company (the "Company")
for the quarterly  period ended March 31, 2009,  filed with the  Securities  and
Exchange  Commission  ("SEC")  on May  15,  2009  (the  "Original  10-Q").  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-Q 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-Q and the  Company  has not  updated
disclosures  included therein to reflect any events that occurred  subsequent to
the date of the Original 10-Q. Accordingly,  this Amendment No. 1 should be read
in  conjunction  with the Original 10-Q and the Company's  filings made with the
SEC  subsequent to the filing of the Original 10-Q. The filing of this Amendment
No. 1 shall  not be deemed an  admission  that the  Original  10-Q,  when  made,
included any untrue  statement of a material fact or omitted to state a material
fact necessary to make a statement not misleading.
