First look to see that levers arenot fouled, hand brake set, or retainingvalve turned up, then take oil plug out ofthe brake cylinder. 2. Why will thisbrake not release by bleeding the auxil-iary reservoir at bleed-cock? A.— the leakage groove is stoppedup and the slide valve stays on its seat,because of strong spring on its back, orsticky oil. Any brake in good conditionshould release when bled. (148) G. W. H., Streator, 111., writes: I am having some trouble with a 9-inch Westinghousc pump this last week;it will run fine for 10 or 12 miles, and then. OD CD CD CD QT NEW YORK CENTRAL TYPE OF LOOP PIPING FOR DRIVER would be about 62 or 63 pounds. 2. Sup-pose (the same train) I charge up to 70pounds train line (set retainers, and theyhold IS pounds in brake cylinders aftermaking reduction of 10 pounds in train).I then recharge to 70 pounds train line,and make as large a reduction as willequalize train line brake cylinder andauxiliary reservoir. How much pressurewill I get? A.—2. About 53 to 56pounds. (150) P. W. S., Princeton, Ind., writes-Referring to your published descrip-tion and illustration of the AutomaticDouble-Heading Feed-Valve device onpage Si. Now. as I see it, the device onthe second engine is wide open to mainreservoir pressure when brakes are re-leased. The pump is recharging themain reservoir, and the pressure is risingon the under side of piston 7, and also iiithe train line and auxiliary
