Abstract: A set-off apparatus for moving a railway carriage transversely off the track includes eight vertically adjustable jacks arranged in four pairs. Two of the jacks of two of the pairs are arranged in each corner of the railway carriage frame, and two pairs of jacks are arranged at each frame end, one of the pairs of jacks being stationary with respect to the frame and the other pair of jacks being displaceable with respect to the frame in a direction extending transversely to the track. A horizontally extending, double-acting cylinder-piston device is arranged for displacing each other pair of jacks transversely whereby the carriage may be transversely set off stepwise while supported in a stilt-like manner.
