Steel Dynamics to Supply Welded Rail for New England Project

FORT WAYNE, Ind., Dec. 23, 2010 /PRNewswire/ — Steel Dynamics, Inc. (Nasdaq:
STLD) today announced that its Structural and Rail Division at Columbia City,
Indiana, is supplying 28,500 net tons of Continuous Welded Rail (CWR) to its
strategic rail distributor, Pittsburgh-based L.B. Foster Company, for
installation on the New England Central Railroad (NECR), an operating subsidiary
of RailAmerica, Inc.

L.B. Foster will be delivering the new rail to Vermont for use in New England
Central’s “Vermonter” project. Funding of the project, a part of the Federal
Railroad Administration’s High-Speed Intercity Passenger Rail Program, was
awarded to the State of Vermont from the American Recovery and Reinvestment Act.

To be completed by mid-2012, the project is to improve Vermont’s state-supported
Amtrak service in this region on a continuing basis.The new welded rail will
improve the speed of intercity passenger service and add capacity for freight
carloads. Steel Dynamics is supplying rail to upgrade approximately 140 miles of
NECR track.

According to Paul Kotsenas, SDI’s Manager of Rail and Special Products, “Steel
Dynamics’ role is to provide the highest-quality standard rail possible in the
longest lengths possible. SDI is producing the 115RE Standard Strength rail in
240-foot lengths and welding these rail sections into 1600-foot continuous
strings at our weld plant adjacent to the rail mill.”

The first of the trainloads of welded rail are being loaded onto L.B. Foster’s
specially equipped CWR trains. The completed order will incorporate eighteen
trainload shipments of welded rail to be delivered by mid-2011 for installation
at various locations throughout Vermont.

L.B. Foster manages the trackside off-loading of the rail. “The convenience of
our own weld train and our jobsite-management capabilities help to expedite
deliveries and minimize off-loading time along this busy route,” said Greg
Lippard, Vice President, L.B. Foster Rail Sales.

To continue to support the world rail community, Steel Dynamics recently
completed a $1.2 million upgrade of its Rail Testing and Inspection unit. SDI
also is embarking on a $17.5 million capital improvement project to streamline
processing in the Rail Mill Finishing area.

L.B. Foster Company (Nasdaq: FSTR) provides materials and services for the
construction and maintenance of transportation, utility, and other
infrastructure projects. It is based in Pittsburgh, PA.

RailAmerica, Inc. (NYSE: RA) owns and operates short line and regional freight
railroads in North America, operating a portfolio of 40 individual railroads
with approximately 7,300 miles of track in 27 U.S. states and three Canadian
provinces.
