1. In a railroad train having a brake system including a fluid carrying brake pipe having an exhaust and connecting a lead locomotive and at least one remote locomotive, the train further comprising a communication system for communicating between the lead locomotive and the remote locomotive, a method for adaptively determining a brake application level for signaling a remote locomotive of the train during a communication loss comprising:

  • determining a brake system operating condition of the train;

    determining an operability condition of the communication system;

    identifying an operator commanded brake application level at the lead locomotive during a communication system inoperability condition, anddetermining a signaling brake application level sufficient for signaling the remote locomotive via the brake pipe responsive to at least one of the brake system operating condition, the operability condition of the communication system, and the operator commanded brake application level.
