Electronic configurable equalizing reservoir backup system

An equalizing reservoir backup system that offers air brake control to the operator when the air brake network has failed or when the computer control equipment of the air brake system has failed. The system includes an equalizing reservoir backup module that is programmed to receive the electrical signals from human machine interface and configuration messages from the computer controlled braking system via the network and to control the train brake pipe via equalizing reservoir control. The equalizing reservoir backup module follows network pressure commands when commanded to do so or transforms handle commands into equalizing pressure when commanded to do so or when communications with the network have been lost. As a result, the backup system can be used when the network has failed or when the computer equipment has failed.
