Models of Westinghouse-American Driver lirakes surplus pressure ; but in an emergency application of the brakes the admission of airinto the brake cylinders from both the auxiliary reservoirs and the train line isthrough openings so much larger than the exhaust ports of the reducing valvesthat the excess pressure is reduced gradually, and is maintained for a length of timesufficient for the slackening of the trains speed to a speed at which the 6o-pound limitis the maximum efficient pressure. In service applications, of course, the automaticrelease of any pressure above the ordinary fixed limit ensures an even diffusion ofretarding force throughout the train not otherwise obtainable. Additional special parts on the locomotive—one slide valve feed valve ; one feedvalve pipe bracket ; one reversing cock ; two high-speed reducing valves—provide asimple means of cutting off the high-speed pressure so that trains which include carsnot equipped with the automatic reducing valve may be r
