A points driver primarily for the simultaneous, synchronous setting of the points of large radius switches, their fixing, the checking and signalling of their final position, the working cylinder(s) (1) of which that ensure the joint movement of the point rails of the points and the associated setting, fixing and checking units is (are) connected to the operating unit (3), which preferably has a hydraulic accumulator, connected to the hydraulic power supply (4). The essence of the points driver is that the hydraulic working cylinder(s) (1) is (are) installed in the hollow track sleeper(s) (9). The piston rod connections of the hydraulic working cylinder(s) (1) directly or indirectly move the point rails of the points, or the coupling rod(s) (2) of the point rails.
