"CUSHIONED" TRACK

The shock absorbing characteristics of track tie pads is gaining increasing acceptance as railroads witness the growing wear on tracks caused by higher speeds and heavier tonnages, the damage to ballast and ties caused by the pumping action of track. Improved materials are now available for tie pads and economically it is becoming advantageous to invest in this additional material when skyrocketing track maintenance costs are considered. Three cushioning systems are described: (1) a pair of pads between the tie plate and the rail and between the tie plate and the tie; (2) rail-base encasement in place of the tie plate; (3) concrete slab track. Initial installations over a sixteen year period has shown a 50% maintenance cost reduction.
