Abstract
A train for carrying out the renewal of a railroad switch or crossing in a track comprises two chassis with a girder between them supported by two cranes on the respective chassis. Cross beams on the girder have hooks for gripping the switch or crossing. The girder is suspended from the cranes by rotary joints and an auxiliary winch has a cable connected to the switch or crossing off-center to provide for tilting the switch or crossing. At least one of the chassis is provided at its four corners with articulated arms and extensible columns provided with bogies for running on side rails. The arms can be swung in so that the bogies can run on standard gauge track.
