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).
