Abstract
Damping elements physically contact some of the coils on one or more mechanical coil springs disposed between a railway car body and a truck. The coils contacted may be at the ends of the springs or at areas between the ends. When double springs are involved, with one being spaced within the other, the damping elements are disposed in the space between the springs at the ends thereof.
