ABSTRACT OF THE DISCLOSURE: Device intended to be displaced along the track of rails and comprising a frame guided by the rail provided with a grinding wheel working through its periphery. To uniformly distribute its wearing through the rail on all its active surface, the grinding wheel is driven, on top of its continuous rotative movement obtained through a driving motor, in an alternative movement transversal to the track by means of an actuating mechanism. This actuating mechanism comprises a motorgear assembly driving an eccentric shaft on the exentric of which the movable support is hinged. To avoid the formation of sinusoidal traces due to the grinding the amplitude a of the reciprocal movement is linked by a relation a ? l-f to the width l of the active surface of the grinding wheel and to the width f of the portion of the profile of the rail which is ground.
