Abstract

A vital radio based automatic train control system that will interface seamlessly with existing onboard ATC equipment via existing track receiver inputs or directly. The invention provides a means of extending ATC signal territory with reduced equipment installation as compared to traditional cab or wayside based ATC. The invention can be used to reduce train braking distances and reduce headway. Furthermore, the radio cab signal can be used for additional purposes including but not limited to wayside equipment monitoring and rolling equipment monitoring.

Claims

1. A method for train control and signaling, said system comprising:

A radio signal;

A train location system;

An apparatus carried on-board that can receive the radio signals and train location data then output a coded carrier to carborne ATC equipment.

2. A method according to claim 1, wherein the on-board apparatus can disconnect the track receiver outputs and connect the apparatus output into carborne ATC equipment.

3. A method according to claim 2, wherein the disconnect and reconnect device is a vital relay.

4. An apparatus carried on-board that receives radio signals and a location signal and outputs a coded carrier.

5. The apparatus in claim 4 where said apparatus controls a switching device that would disconnect the track receiver outputs from the carborne ATC equipment and connect the apparatus coded carrier outputs to the carborne ATC equipment

6. The apparatus in claim 4 in which radio signals may also be sent.
