ABSTRACT:
A retarder, suitable for mounting with respect to a rail of a railway track for reducing the speed of a wagon rolling along the track, includes an hydraulic unit a portion of which, for retardation of the wagon, is disposed in the path of a wheel of the wagon. That portion when engaged, directly or indirectly, by the wheel is deflected by, and out of the path of, the wheel. A thruster device, disposed alongside the unit and capable also of deflecting the portion out of the path, includes a displaceable element which is normally disengaged from the portion but which upon initial movement thereof is so tilted that a part thereof comes into driving engagement with the portion. On continued movement of the element the driving engagement is maintained and the portion moves from its position in the path of the wheel into another position out of the path.
