Characteristics in service of electro-pneumatic brakes and calculation of brake rigging efficiency are discussed. If I.P. feed valves are used, a variation in setting can also produce variations in the rate of rise of brake cylinder air. Differences in brake cylinder stroke can also cause considerable variations in rates of rise. A record of an emergency stop is shown where the brake cylinder air has been controlled by a retarder, blow-down valve, and additional relay vent valve. The restrictions which can cause variations in rate of feed through triple valves appear with an E.P. brake in other places, in, for instance, the variation in lift of an application valve.
