ABSTRACT:
A variable spring group for a railcar wheel truck assembly, which spring group has independent variable rate control springs for biasing snubber assemblies of a bolster in the wheel truck assembly, with the spring group having a first linear spring rate at an empty-railcar condition and a second linear spring rate at a loaded railcar condition that is at least five times as great as the empty-car spring rate, and the control springs are variable rate springs with a first and empty-railcar rate and a second and loaded-railcar spring rate, which is about twice the empty car control spring rate.
