The ATP Loadmaster resilient track fastener was specifically designed to provide railroads with a greater range of options for bridge, tunnel or slab applications. The ATP Loadmaster's rugged durability has been tested in the most demanding environments and can stand up to heavy loads and high traffic.




The Loadmaster's containment design provides innate "fail safe" characteristics not seen in similar products. This resilient fastener will match the track modulus of ballasted track. The ATP Loadmaster has been in service for more than 20 years and has required little to no maintenance in track.



The ATP Loadmaster is the only resilient fastener tested and designed for 40-ton axle load and the product achieved 400 MGT without maintenance while maintaining class 9 track tolerances. The ATP Loadmaster is such a durable product it reduces impact forces on supporting structure, some suggest even the rail lasts longer!
