ABSTRACT:
A control circuit for reducing the output cycle of a compressed air system of a rapid transit car during "lay-over" periods, when only a minimum of compressed air for a parking brake, for example, is needed by the car, by activating a secondary governor set for a low pressure operating range and connected in series with a primary governor, one or the other of the governors being activated by the control circuit responsively to control signals denoting the state of compressed air requirement of the car.
