An apparatus (1) for grinding rails (2) includes a carrier frame (3) designed to roll on the rail via tracer rollers (4) having axes of rotation (5), the carrier frame being mounted for pivoting about a pivot axis (7), extending in the longitudinal direction of the rails, on an assembly frame (8) having guide rollers (22) for rolling on the rail. Tracer- as well as guide rollers (4,22) exhibit a respective rolling surface (43,44) intended for rolling on the rail (2). A guiding member (40), designed for application to a vertical side surface of the rail (2), is connected to the assembly frame (8) so as to be able to be distanced with respect to the carrier frame (3), whereby with the axes of rotation (5) of the tracer rollers (4) being positioned horizontally parallel to axes of rotation (23) of the guide rollers (22) - a roller contact point (46), defined by contact of the rolling surface (44) with the rail (2), of the guide roller (22) is arranged at a distance from and positioned higher with regard to a roller contact point (45) of the tracer roller (4). A pivoting drive (30) is provided for pivoting the assembly frame (8) relative to the carrier frame (3).
