摘要

Machine for truing the bearing surface of the rails of a railroad track. The machine which is movable over the rails to be trued has a frame on which is mounted a train of grinding elements to be driven one behind the other over and along the rails tangentially of the bearing surface to remove irregularities. The machine is characterized in that at least one of the grinding elements can be displaced in a direction toward or away from the bearing surface of the rail to be trued to reach a desired position and can be locked into this desired position.
