Abstract
A computer controlled locomotive brake (CCB) configured for setting and releasing the automatic parking brakes of the railcars of a train. The CCB may initially recharge the brake pipe to a pressure slightly less than the parking brake unlatch pressure. The CCB may then continue charging to this level until the brake pipe flow, measured at the CCB on the controlling locomotive and the brake pipe pressure on the last car, as measured by an end of train device, indicate that the pressure in the braking system reservoirs are substantively equal to the brake pipe pressure. Once the reservoirs are substantively charged, the CCB may complete the brake release and recharge by recharging the brake pipe pressure to its final charge so that all parking brakes are released and the train has sufficient braking system recharge to safely control movement of the train.
