L.B. Foster Company: Contact Rail

L.B. Foster Company

Three basic contact rail systems are available from L.B. Foster. The aluminum/stainless-steel co-extruded composite rail provides one of the best available electrical performances per pound, the company says. The co-extrusion process metallurgically bonds the rail's aluminum body to a stainless-steel wear strip, while the aluminum provides high conductivity; the stainless steel provides shoe wear capability matching that of steel rail, the company says. Traditional non-composite steel rail is heavier with electrical performance half that of newer systems, the company says. The third type of rail is the steel/aluminum composite rail, which consists of aluminum strips fastened to the webbing of conventional steel rail that provides the height, wear surface and base. The aluminum elements are joined by Huck-type fasteners for steel-to-aluminum contact.
