Press Release


                    Providence and Worcester Railroad Company
                          Announces Project Milestones

     Worcester,  MA, July 26, 2006.  Providence and Worcester  Railroad  Company
(AMEX:  "PWX") today  announced  progress  relating to the Company's  South Quay
property and the Freight Rail Improvement  Project  ("FRIP"),  two projects that
have been ongoing for a number of years.

     Yesterday,  a groundbreaking  took place for the Warren Avenue extension in
East  Providence,  Rhode Island,  a Rhode Island  Department  of  Transportation
roadway  improvement  that will  provide  a direct  link  between  I-195 and the
Company's South Quay property.  The South Quay consists of a total of forty-five
acres in two parcels - a  thirty-three  acre parcel  that was  tide-flowed  land
filled by the Company and an existing  twelve-acre  parcel.  The  Company's  fee
simple title to the  thirty-three  acre parcel was confirmed by the Rhode Island
Supreme Court in a landmark  decision in 1999.  The Rhode Island  Superior Court
confirmed the Company's fee simple title to the twelve-acre  parcel in 2000. The
property is located a half mile from Route I-195. The principal  planner for the
City of East  Providence  was recently  quoted in a published  article as saying
that the link to the  highway is  believed  to be  "critical  because,  from the
standpoint of developers, one of their greatest concerns is having direct access
to the interstate."  The project is anticipated to be substantially  complete by
2007.

     The FRIP was  originally  proposed  by the  State  of Rhode  Island  in the
mid-1990s to increase the capacity of the electrified Northeast Corridor along a
twenty-two-mile  corridor from Central Falls, Rhode Island,  through Providence,
to Quonset Point/  Davisville and to increase  overhead  clearances to allow for
the  movement of modern rail  equipment,  thereby  enabling  development  of the
State's Quonset  Point/Davisville  port  facilities.  The FRIP track consists of
seventeen miles of dedicated freight track (ten miles of which are new track and
seven  miles of which  were  rehabilitated),  while  the  balance  of the  route
consists  of shared  use of two  rehabilitated  electrified  main lines for five
miles). Construction commenced in 2002 at a cost of $148 million to the State of
Rhode Island and the federal  government and is scheduled to be completed by the
third  quarter  of 2006.  As of now,  the  inaugural  train on the FRIP track is
tentatively scheduled for the end of August, with regular service to commence in
September 2006.

     In a letter to Company shareholders dated July 26, 2006, PWX President,  P.
Scott Conti,  stated that,  "The Company looks forward to the  completion of the
Warren Avenue  extension and the  inauguration of service on the FRIP track with
great anticipation."

     In addition,  the Company  announced that, at its regular quarterly meeting
on July 26, 2006,  the Board of Directors of the Company  declared a dividend of
$.04 per share on the  outstanding  Common Stock of the Company,  payable August
21, 2006 to shareholders of record on August 7, 2006.
