A system for variably controlling the purge cycle of a locomotive air supply system air dryer pre-filtration state. A sensor in the air inlet of the air dryer provides temperature information to a controller, which calculates an appropriate purge cycle time based on the saturation partial pressure of water vapor at the actual temperature of the air entering the air dryer and the operates the drain valve according to the particular purse cycle time.
