Abstract
A train control system includes a communication device associated with at least one control unit located on a first train; and a communication device associated with at least one control unit located on a second train. At least one of the control units of the first train and the second train is configured to receive, at the associated communication device, an authority signal including data sufficient to identify one of the first train and the second train as a lead train and the other of the first train and the second train as a follower train, establish at least one peer-to-peer communication link between the communication devices of the lead train and the follower train, and exchange train data between the lead train and the follower train via the at least one peer-to-peer communication link. An on-board control unit is also disclosed.
