Abstract
A braking control system for a vehicle system includes a control chamber configured to control air pressure of a brake pipe of the vehicle system. The system also includes first and second charge valves and first and second vent valves. The first charge valve and the first vent valve are controllable to vent or charge the brake pipe, and the second charge valve and the second vent valve are separately controllable for the same purpose. The system also includes a controller configured to switch operation of the vehicle system between a first operation mode, where the first charge valve and the first vent valve are enabled, and a second operation mode, where the second charge valve and the second vent valve are enabled, in response to an input.
