A rail vehicle braking system includes a service brake (6) having a movable piston (8) delimiting with a body (2) of the system a service brake chamber (13) supplied by a first source, and a parking brake (7) having a blocking device (20) having a position in which it immobilizes the piston in a position, and a movable actuating device (23, 24) delimiting with the body a parking brake chamber (25) supplied by a second source and having a stable position in which it holds the blocking device in its position; the service chamber, when the actuating device is in its stable position, being supplied by the second source of which the pressure is greater than that of the first source in order to apply a greater braking force than the force applied when the piston is in its position.

A control system is described for a railway convoy, particularly for the transport of goods, comprising wagons, a master locomotive and at least one slave locomotive. The railway convoy comprises a brake pipe which extends along the entire railway convoy. The master locomotive is arranged to control the pressure in the brake pipe and to send traction and/or braking commands to the slave locomotive by means of a communication channel. The at least one slave locomotive comprises a transceiver means arranged to receive the traction and/or braking commands and to re-transmit them to a traction control unit and to a brake control unit of the slave locomotive. The control system includes a safety unit arranged to prevent a relay valve from supplying the pneumatic brake pipe when at least one malfunction condition of the control system for a railway convoy occurs.
