FOR IMMEDIATE RELEASE


                    Foster Announces Sale of DM&E Interest


PITTSBURGH,  PA,  September 5, 2007 - L.B.  Foster Company  ("Foster")  (Nasdaq:
FSTR),  today  announced that the Canadian  Pacific  Railway  Limited ("CP") has
reached an  agreement  to acquire  the Dakota  Minnesota  and  Eastern  Railroad
("DM&E") in which Foster holds a minority equity interest.  The deal consists of
a $1.48 billion cash payment at closing and future contingent  payments of up to
approximately  US $1 billion.  Future  contingent  payments  of US $350  million
become due if construction  starts on the Powder River Basin  Expansion  project
prior  to  December  31,  2025.  Further  future  contingent  payments  of up to
approximately  US $700  million  will become due upon the  movement of specified
volumes  of coal  from the  Powder  River  Basin  over the  Powder  River  Basin
extension prior to December 31, 2025.

     For  Foster,  the  acquisition  will  result in a payment of  approximately
$151.5   million  at  closing   ($14.24/share),   approximately   $41.6  million
($3.90/share)  upon  commencement  of  construction  of the PRB, and up to $84.2
million  ($7.90/share)  upon  achieving  milestones  related to PRB coal tonnage
thresholds.  The above numbers, which are subject to adjustments both before and
after  closing,  are all  pretax  except for the  payment at closing  which will
include  approximately  $17.4  million  of  return  of  investment  and  accrued
dividends.

     "This is a wonderful  outcome for the L.B. Foster  Company",  stated Lee B.
Foster,  the  Company's  Chairman.  "We  were  privileged  to be a  part  of the
formation of the DM&E in 1986 and to witness and  participate in its growth from
an abandoned  property of the Chicago and Northwestern  Railroad to the nation's
largest regional railroad with a valuable franchise to extend its operation into
Wyoming's  Powder  River  Basin.  Kevin  Schieffer's  leadership  as well as the
determination  and imagination of the management team and the Board of Directors
of  the  DM&E  have  resulted  in  a  success  story   unparalleled   in  modern
railroading."

     "The Canadian Pacific was the DM&E's natural partner" continued Mr. Foster,
"and their  commitment  to the PRB was an important  element of the M&A process.
This is truly a winning solution for all involved."

     Fully  committed  acquisition  financing  has been obtained by the Canadian
Pacific  and  the  closing  is  expected  within  30 to  60  days.  The  CP/DM&E
transaction  is subject to review and  approval by U.S.  Surface  Transportation
Board  (STB),  during  which  time the  shares of DM&E  will be  placed  into an
independent  voting  trust.  The review  process is expected to take less than a
year,  at which  time the  operation  is  expected  to become  part of CP's U.S.
network.  The voting  trust is required  by US law so that CP does not  exercise
control over DM&E prior to approval of the transaction by the STB.

     "With the impending sale of the DM&E, an interesting and profitable chapter
in the history of L.B.  Foster  comes to an end,"  commented  Stan  Hasselbusch,
President and CEO. "We are obviously very pleased with the terms of the sale and
I am especially enthusiastic about the future of L.B. Foster and the flexibility
that the proceeds described above afford us.

     "The  proceeds  generated  from this  transaction  will be used to pay down
certain debt and help fuel key long term strategic growth  initiatives  designed
to bring continued  profitability and maximize value to our  shareholders",  Mr.
Hasselbusch concluded.

     L.B.  Foster Company will conduct a conference  call and webcast to discuss
this  transaction on Friday,  September 7, 2007 at 10:00 am ET. The call will be
hosted by Mr. Lee Foster, Chairman. Listen via audio on the L.B. Foster Website:
