A braking system, including a brake control arrangement in operational communication with a braking arrangement for braking a vehicle, and a penalty power source to deliver current or power to the brake control arrangement through a brake interface circuit. The brake interface circuit includes a main positive current switch urged to a closed position and configured to open upon loss or interruption of a penalty hold-off signal, and a main negative current switch urged to a closed position and configured to open upon loss or interruption of a penalty hold-off signal. Upon opening of either of the main positive current switch or the main negative current switch, the braking arrangement will automatically brake the vehicle as controlled by the brake control arrangement.
