RELIEF VALVE FOR SUPERHEATERLOCOMOTIVES By W. B. MIDULETONGeneral Roundhouse Foreman, Atlantic Coast Line, Rocky Mount, N. C. The lubrication of the cylinders of superheater locomotiveswhen drifting is a problem which has presented considerabledifficulty. Where relief valves are used the inrush of air whenthe throttle is closed causes carbonization of the oil, at thetemperatures found in the steam passages; this results in thedestruction of its lubricating qualities and the accumulation ofcarbon on the cylinder walls and in the steam ports. In manycases the use of the relief valve has been discontinued in orderto prevent this action, with considerable benefit in the elimina-tion of carbonization. But without the relief valve there isdanger of the locomotive moving with no one in charge, owing.
