Railroad vehicle for the reprofiling of at least one rail of a railway track, includes a frame provided with wheels resting on each rail. At lest two reprofiling units are supported by the frame, having each a motor, the shaft of which carries at each end a rotative tool. A support carries the grinding units; and the support is connected to the frame in such a way as to permit displacing the support vertically and transversely with respect to the frame. The reprofiling units comprise further structure to apply one of their tools against a rail. The support is displaceable with respect to the frame in rotation and/or translation. Each reprofiling unit is mounted on the support by a rotating table the rotation axis of which is perpendicular to the axis of rotation of the motor of the unit and by a slide extending perpendicularly to the longitudinal axis of the rail so that the motor shafts of the motors of the two grinding units can be displaced the one with respect to the other, firstly, in rotation around an axis parallel to the longitudinal axis of the rail, and secondly, in translation parallel to a plane which is perpendicular to the longitudinal axis of the rail.
