A system (900) for communicating data (904) in a train (902) is provided. The system (900) includes at least one respective router transceiver unit (916) positioned in each of at least two rail vehicles (908, 910, 912) of the train (902). Each router transceiver unit (916) is coupled to a trainline (906) that extends between the rail vehicles (908, 910, 912). The trainline (906) is an existing cable bus used in the train (902) for transferring propulsion control data (914) between the rail vehicles (908, 910, 912) that controls at least one of tractive effort or braking effort of the rail vehicles (908, 910, 912). The router transceiver units (916) are configured to communicate network data (904) over the trainline (906). In one embodiment, the trainline (906) is an Electrically Controlled Pneumatic (ECP) trainline and the propulsion control data (914) is ECP brake data used to control operations of brakes in the train (902). |
