Moral—Dont let all the air out of thetrain pipe if you want the brakes to holdwith a service application. There may bea leaky check valve in some triple. Here is another: In company with someair-brake experts, a visit was paid by thewriter to a test of some newly inventedtriple valves. A fifty-car rack was used,and the brakes were operated with a D-5valve. The triples were not Westing-house. A very heavy service reductionwas made from 70 pounds down to 40pounds in the train pipe. When the handleof the valve was lapped, the equalizing. Lig. C. & ST. L. ItY. AIR-BUAKR (,AIt.
