The grinding machine comprises A grinding head with a rotary abrasive tool, carried by a chassis equipped, at its ends, with rollers for running and. guiding on the rail that is to be ground. A balancing assembly, resting on the other rail of the track, is mounted to pivot on the chassis, also provided with an orientable maneuvering arm. To rotate the grinding tool, an internal combustion engine is fixed to a support articulated to the balancing assembly, the horizontal output shaft of the engine being connected by a transmission assembly to the grinding head. The machine makes it possible to grind the profile of the head of the rail through an angle of 180° while at the same time avoiding excessive inclination of the engine.
