ABSTRACT:
A railway car positioning carriage movable back and forth along a track parallel to a railway track is provided with a member for engagement with the end of a car on the railway track to move it. A pair of sheaves are rotatably mounted on the carriage, and first and second anchor devices are disposed at opposite ends of its track. A wire rope is secured at one end to each of the anchor devices and each rope extends therefrom toward the carriage and around one of the sheaves. The other ends of the ropes are connected to a member for pulling on either rope while simultaneously paying out the other one to thereby pull the carriage along its track. One of the ropes can be temporarily released from its anchor device and detachably connected to the carriage, which can then be pulled by the other rope so that the carriage will pull the released rope across its anchor device to take up slack in the ropes.
