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.

A control system may include a modulator device that may receive a control signal for changing a traction operation or a braking operation of a vehicle system formed from one or more vehicles. The modulator device may generate an electric modulator signal based on the control signal and may control an actuator using the modulator signal to create an acoustic signal for propagation within a conduit extending along the vehicle system. The system also may include a transducer device that may detect the acoustic signal propagated in the conduit and generate an electric transducer signal based on the acoustic signal. The system may include a demodulator device that may control one or more of a traction device or a braking device to implement the control signal based on the transducer signal that is received.
