Publication number: 20230150556Abstract: 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.Type: ApplicationFiled: April 27, 2021Publication date: May 18, 2023Inventors: Angelo Grasso, Roberto Tione, Roberto Correndo
