ABSTRACT:
The sole of each rail of a railroad track rests at regular intervals on a cushion of shock-absorbing material, the stiffness of each shock-absorbing cushion being such that the cushions form alternate resilient and rapid supports. Each cushion is placed in a shaped housing in a concrete sole plate and the rail is fastened on the sole plate. The concrete sole plates of the rail can be fastened into the ground, possibly with the interpositioning of an anti-vibration sole plate, or can be fastened on a concrete slab which is laid over anti-vibration supports.
