This triplevalve is a simplification of the earlier de-sign that was used in the tests on theVirginian Railroad in 1918, and performs tonnage, when loaded, of about 4,445 tunsexclusive of the engine and the caboose.A preliminary test was made of one ofthese trains, made up exclusively of carsequipped with the A. S. A. brakes, onFebruary 15, 1921, between Bluefield,West Va., and Roanoke, Va., a distanceof about 103 miles. The profile of thissection of the road consists, as shownby the accompanying profile, of a downgrade for 24 miles, that averages about lowed by lighter grades into RoanokeIn addition to the running test a num-ber of standing tests were made. Theresults of the whole were so satisfactorythat it was decided to make a similar testwith a train made up of seventy of these100-ton cars, all equipped with the A. S.A. brake. The tests were run on March 24 to 26inclusive. The standing tests were madein the Bluelicld yard. It was found

The application of these brakes to thecars was begun last October and, sincethat time, as the cars were put into serv-ice, they have been running in trainsmixed in with the regular brakes. The regular length of a train made uprf)f these cars is thirty-five, giving a total 1.3 per cent, though there is a sectionabout two miles long near Bluefield, of1.6 per cent. This is followed by anup grade for 47 miles; the first 39 ofwhich is up the New River and averagesabout 0.1 per cent, with short sections of0.2 per cent, and level stretches. Thenthere is a run of 8 miles up the westernslope of the Allegheny Mountains on agrade of about 0.9 pe
