Abstract:
1. A method for accumulating air in an auxiliary reservoir of a railroad car, comprising: charging an air brake system, the air brake system comprising a brake reservoir, a brake cylinder, and a control valve configured to release air from the brake reservoir directly to the brake cylinder, such that the brake reservoir is in direct fluid communication with the brake cylinder through the control valve, in response to receiving a braking signal; bleeding air directly from the brake reservoir to the auxiliary reservoir through a port in the control valve when air pressure in the brake reservoir increases to a predetermined value, the air bled directly from the brake reservoir to the auxiliary reservoir being air that has not travelled to the brake cylinder before reaching the auxiliary reservoir after being accumulated in the brake reservoir; and accumulating the air bled directly from the brake reservoir in the auxiliary reservoir through the control valve, the auxiliary reservoir configured to supply the air from the air brake system to an auxiliary component, the bleeding air from the brake reservoir through the port in the control valve occurring during normal operation.
