ABSTRACT:
Apparatus for rerailing derailed wheels of a railway vehicle includes a bridge which is positioned beneath a derailed vehicle end. After the vehicle is leveled, a lifting jack disposed on a carriage mounted on the bridge supportingly elevates the derailed vehicle end and moves the supported derailed end over the rails, the bridge being positioned to return the derailed vehicles to a position over the rails. Since the wheels of the opposed vehicle end are stationary, the derailed vehicle end is moved along an arcuate path. A motive means such as a jack moves the carriage along the bridge axis, and supporting roller means on the carriage enable the lifting jack engaging the vehicle to move transversely to the bridge axis thereby allowing the jack and supported vehicle end to traverse an arcuate path while fully supported.
