ABSTRACT OF THE DISCLOSURE Apparatus for the continuous on-track truing of railway rails, the apparatus consisting of two parts symmetrical with respect to the longitudinal axis of the rails, each part comprising at least four contact elements including abrasive elements, the contact elements constituting points of support of the part of the apparatus on the corresponding rail, means dividing the contact elements into at least two longitudinally aligned groups, the contact elements in at least one of the groups being fixedly arranged therein on a common support. Parallel bar linkage means hingedly connect the at least two groups together so that they are adapted to move independently of but parallel to one another in a vertical direction when passing over undulations of the rail, such that the contact elements of each group remain in respective horizontal planes and oscillate vertically over the undulations, at least one contact element of each group contacting the rail at all times. Means are associated with the groups for causing each group to exert individual independent pressure on the rail which is to be trued.
