Method and apparatus for grinding the tread and/or guide surfaces of rails or the like ABSTRACT A method for grinding the running and/or guide surfaces of rails or the like wherein the surfaces are ground by a continu- ous, rotating abrasive belt that is movable against them, the running and/or guide surfaces of the rail being ground by the abrasive belt that travels transversely to the longitudinal axis of the rail and when prestressed is at least partially wrapped around the running and/or guide surfaces, as well as a device to realize the method. The device comprises a grinding machine movably guided on at least one rail of the track, this grinding machine having a continuous abrasive belt which rotates about a drive pulley and a deflection arranged at a distance thereto and is movable by them against the surfaces of the rail to be ground, characterized in that the deflection is formed by two deflection pulleys (16, 17) arranged a relatively short distance from one another, that the axes of the deflection pulleys (16, 17) and the drive pulley (19) are arranged parallel to the longitudinal axis of the rail (3) and the abrasive belt (22) thus rotates transversely to the longitudinal axis of the rail (3), and that at least one deflection pulley (16, 17) can be lowered below the upper edge of the running surface (2) of the rail (3) to at least partially wind around the surfaces (2) of the rail (3).
