1. A system comprising:

  • a remote controller for issuing commands to a brake system of a remote unit of a distributed power rail vehicle, the brake system including a brake pipe having a brake pipe fluid (BPF) pressure, wherein the remote unit is configured to communicate with a lead unit of the distributed power rail vehicle through a communications system to coordinate braking of the distributed power rail vehicle, the remote controller configured to determine that a communication loss exists between the lead and remote units, the remote controller further configured to receive pressure signals from a sensor that detects the BPF pressure at the brake pipe of the remote unit and to identify, during the communication loss, an initiated brake application based on received pressure data, the remote controller also configured to issue commands during the communication loss to the brake system to reduce the BPF pressure of the brake pipe to a default pressure level.
