System and method for communicating data in a train having one or more locomotive consists

摘要

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