A mobile rail grinding machine for grinding the running surface of the rails of a track comprises a grinding module mounted for power-driven vertical movement on a machine frame which runs on undercarriages on the track rails. The undercarriages have flanged wheels pressed without play against the track rails. The grinding module is associated with a respective track rail and is arranged laterally adjacent a respective side of the track rail. It includes a carrier frame, a grinding unit carrier mounted thereon adjustably positionable relative to the machine frame and the carrier frame, a grinding unit mounted on the grinding unit carrier, and a shaping tool for profiling the grinding surface of a rotatable grinding tool of the grinding unit which is arranged for continuously grinding one side of the track rail running surface as the machine frame and the grinding unit move in the operating direction.
