The West German Federal Railroads eliminated surface damage to the rail head first by means of the Krupp grinding train consisting of one car with a power generating set and three cars equipped with rotating, elastically suspended grinding wheels, later by means of the Schorling grinding train with four grinding cars, each provided with four pairs of grinding stones 70 cm in length. Since 1970 the much more rapid Speno grinding train was used which reaches 15 km/day or 5000 km/year at an operating speed 6 to 7 km/h. The train consists of nine grinding cars with 58 rotating, tiltable grinding wheels, one car with a power generating set, one control car and one accommodation car. The treatment includes running surface and running edge. In 1971 a track length of 3555 km was treated on a grinding travel of 4875 km.
