Abstract

A system comprises a control module that is configured for operable coupling with at least one of a brake system and/or a penalty detection system of a first vehicle. The control module is further configured to operate in a first mode of operation. In the first mode of operation, the control module activates the brake system, responsive to receiving a first control signal from a second vehicle; the first and second vehicles are coupled in a consist. Alternatively or additionally, the control module is configured to operate in a second mode of operation. In the second mode of operation, the control module is configured to generate the first control signal for transmission to the second vehicle and activation of a brake system of the second vehicle, responsive to receiving a second control signal from the penalty detection system.
