The additional trackload clearance demanded by traditional ballasted track construction can be virtually eliminated through the use of direct fixation rail fasteners. With an average height from rail seat to concrete deck of 1 1/2" to 2", direct fixation fasteners are an ideal alternative whenever height clearances are restricted.

By eliminating the need for sub-ballast, ballast and ties, our direct fixation fasteners dramatically reduce the track structure height. Also, the lighter system weight allows for more economically designed supporting structures. Less weight means less costs, a savings felt directly at the bottom line.

Accommodating today's demands for double-stack cars presents many railroads with clearance challenges at existing structures. Retrofitting existing tunnels for additional clearance can be simplified and economized through the use of L.B. Foster Company direct fixation fasteners.
