FOR IMMEDIATE RELEASE


                              L. B. FOSTER COMPANY

                          REPORTS STRONG FIRST QUARTER

                    RESULTING IN 96% INCREASE IN INCOME FROM

                              CONTINUING OPERATIONS

PITTSBURGH,  PA, April 27, 2006 - L.B. Foster Company (NASDAQ:  FSTR), a leading
manufacturer,  fabricator,  and distributor of rail,  construction,  and tubular
products,  today reported that its first quarter earnings per diluted share from
continuing  operations  nearly doubled  compared to the prior year quarter,  the
fifth consecutive quarter the Company has recorded an earnings increase over the
prior year.

2006 First Quarter Results

In the first  quarter of 2006, L. B. Foster had earnings per diluted share of 36
cents and net income of $3.9 million  compared to 6 cents per diluted  share and
net  income of $0.6  million  in the  first  quarter  of 2005.  The  results  of
discontinued  operations  reflect the sale of our  Geotechnical  Division in the
first  quarter of 2006.  Income from  discontinued  operations  of $2.8  million
includes the gain on this sale of $3.0  million,  reduced by a $0.2 million loss
from  operations  during the  period we owned the  business.  Income  taxes were
favorably  affected  by the release of a  valuation  allowance  recorded in 2003
related  to a  capital  loss  carryforward.  Diluted  earnings  per  share  from
continuing  operations  was 11 cents on earnings of $1.2  million  compared to 6
cents on earnings of $0.6 million in 2005.

Net sales increased 24% to $84.2 million  compared to $67.6 million in the prior
year quarter.

Gross profit margin was 11.6%, up 80 basis points from the prior year quarter as
a result of increased  plant  efficiencies  and  favorable  variances in product
purchases.

"Piling and Rail Products  continued to deliver  strong sales.  Our concrete tie
business  results improved  substantially  due to strong activity at our Spokane
facility.  Although our Fabricated Products Division continued to lose money, it
performed  substantially  better  than the prior year  quarter,"  remarked  Stan
Hasselbusch,  President and Chief Executive  Officer.  "We are pleased to report
that tie production in our recently  refurbished Grand Island facility continued
to increase to levels where its first quarter production increased 10% over last
year. We are also pleased to announce that our Tucson  facility  construction is
well underway and on schedule," added Mr. Hasselbusch.

Mr.  Hasselbusch  concluded,  "Overall  business  activity remains strong and is
reflected in our first  quarter order  bookings.  Bookings for the first quarter
were $121 million,  14% higher than the same period last year.  Backlog at March
31, 2006 was $141 million, which was 25% higher than last year."

Selling and administrative  expenses increased $1.2 million or 18% over the same
prior year period due primarily to employee related costs and benefit  expenses.
Fourth quarter interest  expense  increased $0.2 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 was 34.4% in the first  quarter  compared to 30.4% in
the prior year quarter.  The lower tax rate in 2005 is the result of releasing a
portion of the valuation allowance provided for state deferred assets.

Cash flow from operations was a negative $5.9 million for the first quarter, due
to an expected  ramp up in  activity  in  anticipation  of a  seasonally  strong
spring/summer period.  Capital expenditures for the quarter were $5.2 million as
we are working to complete the Tucson concrete tie facility later this summer.

L. B. Foster  Company will conduct a conference  call and webcast to discuss its
first quarter operating  results on Thursday,  April 27, 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
