Short headway communications based train control system
First Claim
1. A train control system, comprising:
- 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;
wherein at least one of the control units of the first train and the second train is configured to;
(i) receive, at the associated communication device, an authority signal including data configured 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;
(ii) establish at least one peer-to-peer communication link between the communication devices of the lead train and the follower train; and
(iii) exchange train data between the lead train and the follower train via the at least one peer-to-peer communication link.

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.

25. An on-board control unit for a train, comprising:
-
a communication device configured to send and receive signals; and at least one computer having a computer readable medium having stored thereon instructions, which, when executed by a processor, causes the processor to; (i) receive, at the communication device, an authority signal including data configured to identify one of a first train and a second train as a lead train and the other of the first train and the second train as a follower train; (ii) establish at least one peer-to-peer communication link between the communication device of the train with a communication device of another train; and (iii) exchange train data between the train and the other train via the at least one peer-to-peer communication link. - View Dependent Claims (26)
