FOR IMMEDIATE RELEASE

                              L. B. FOSTER COMPANY

                          REPORTS STRONG SECOND QUARTER

                    RESULTING IN 93% INCREASE IN INCOME FROM

                              CONTINUING OPERATIONS

PITTSBURGH,  PA, July 28, 2006 - L.B. Foster Company  (NASDAQ:  FSTR), a leading
manufacturer,  fabricator,  and distributor of rail,  construction,  and tubular
products, today reported that its second quarter earnings per diluted share from
continuing  operations increased to $0.29 from $0.15, a 93% increase,  the sixth
consecutive quarter the Company has recorded an earnings increase over the prior
year.

2006 Second Quarter Results

In the second quarter of 2006, L. B. Foster had earnings per diluted share of 28
cents and net income of $3.0 million  compared to 15 cents per diluted share and
net income of $1.6 million in the second  quarter of 2005. The $0.1 million loss
from   discontinued   operations   reflects  the  winding  down  of  our  former
Geotechnical  Division,  which was sold in the first  quarter  of 2006.  Diluted
earnings per share from continuing  operations were 29 cents on earnings of $3.1
million compared to 15 cents on earnings of $1.6 million in 2005.

Net sales  increased 9% to $99.3 million  compared to $90.7 million in the prior
year quarter.

Gross profit  margin was 13.5%,  up 230 basis points from the prior year quarter
primarily as a result of increased billing margins.

Selling and  administrative  expenses  increased  $1.3  million or 18% over last
year's  quarter due primarily to employee  related  costs and benefit  expenses.
Second quarter interest  expense  increased $0.3 million over the prior year due
to increased interest rates and increased borrowings. The increase in borrowings
was due  primarily  to an increase in working  capital  requirements  as well as
higher than typical capital investments made during the past three quarters. The
Company's  income tax rate from  continuing  operations  was 29.0% in the second
quarter compared to 34.6% in the prior year quarter.  The lower tax rate in 2006
is the result of  releasing a portion of the  valuation  allowance  provided for
state net  operating  losses due to a change in the  Company's  estimate  of its
ability to utilize those net operating losses in future periods.

"Construction  Products and Rail Products  continued to deliver strong sales and
more  importantly,  improved  gross  profit  margins.  Our concrete tie business
results  improved  again due to strong  activity  at our Spokane  facility.  Our
precast buildings  business also contributed  significantly  improved margins on
moderately  increased sales and our Fabricated  Products Division  continued its
improvement over last year's second quarter as well as the first quarter of this
year," remarked Stan Hasselbusch, President and Chief Executive Officer. "We are
pleased to report that our recently  refurbished Grand Island facility continued
to increase tie  production  to  anticipated  levels.  Additionally,  our Tucson
concrete tie facility has recently  commenced  test-casting of concrete ties and
will  continue to work through mix design and  mechanical  issues as it prepares
for   commissioning   in  the  September  to  October  time  frame,"  added  Mr.
Hasselbusch.

2006 First Half Results

In the first half of 2006, L.B. Foster had income from continuing  operations of
$4.3 million or 40 cents per diluted share  compared to $2.2 million or 21 cents
per diluted  share for the first six months of 2005.  Income  from  discontinued
operations  for the first half of 2006 was $2.6 million which  includes the gain
on the sale of our former  Geotechnical  Division of $3.0 million,  reduced by a
$0.4  million  loss  from  operations  and wind  down  costs.  The  discontinued
operations  income tax  provision  was  favorably  affected  by the release of a
valuation allowance recorded in 2003 related to a capital loss carryforward.

Net  sales for the first six  months  of 2006  increased  16% to $183.5  million
compared to $158.3 million in 2005.  Gross profit margin was 12.7%, up 160 basis
points  from the first six months of 2005,  primarily  as a result of  increased
billing margins.

Selling and administrative  expenses increased $2.5 million or 18% over the same
prior year period due primarily to employee related costs and benefit  expenses.
Interest  expense  increased  $0.5  million over the prior year due to increased
interest  rates and increased  borrowings.  The  Company's  income tax rate from
continuing  operations  was 30.6% compared to 33.5% in the prior year due to the
same reasons stated in the first quarter discussion.

Cash used from  operations was  approximately  $14 million for the first half of
2006,  due to an expected  ramp up in activity in  anticipation  of a seasonally
strong spring/summer period.  Capital expenditures for the same period were $8.7
million as we continued to progress toward completion of the Tucson concrete tie
facility  and  substantially  completed  our  new  rail  products  manufacturing
facility in Pueblo, Co.

Mr.  Hasselbusch  concluded,  "Overall  business  activity remains strong and is
reflected in our first quarter order bookings.  Bookings for the first half were
$243  million,  32% higher than the same  period last year.  Backlog at June 30,
2006 was $159 million, which was 60% higher than last year."

L. B. Foster  Company will conduct a conference  call and webcast to discuss its
second  quarter  operating  results on Friday,  July 28, 2006 at 11:00am ET. The
call will be hosted  by Mr.  Stan  Hasselbusch,  President  and Chief  Executive
Officer.  Listen  via audio on the L.B.  Foster web site:  www.lbfoster.com,  by
