Abstract
A method of transitioning between the pneumatic and electric modes of an integrated pneumatic/electro-pneumatic train brake system which includes a brake control having a common operator brake controller. Initially, the control applies the brakes in response to the operator brake controller in the present mode. The control enables the next mode upon request from the operator and applies the brakes in the next mode to match the applied brakes in the present mode. Once the present mode brake is released, the control and system switch to the next mode. Other brake controllers monitor the network and automatically switches modes based on the status of the network.
