It should be noted thatthere are two heaters in the locomotive shop, offering the ad-vantage of closer regulation of the heating in moderateweather than would be possible to obtain with a single largeheater. Each of the locomotive shop heaters has 22 sections, eachhaving SO eight-foot pipes and giving a radiating surface of14,740 lineal feet of one-inch pipe. The blower is the Bostonsteel plate exhauster with full housing. The height of thefan is about 10 feet, the fan wheel is 72 inches in diameter by34 inches wide at the periphery, and 42 inches wide over all.The inlet has a diameter of 50 inches, while the outlet is 44by 40 inches. The housing is of heavy steel plate, braced withT and angle iron. The fan is directly connected to a seven byseven-inch engine, as usual in this system of heating.

To reach the heaters in the different shops an extensive sys-tem of underground sleani and return piping was necessary.This system is conducted through trenches of ample size, allof which are given pronounced slopes for drainage not only ofthe pipes, but of the trenches themselves. They are providedwith concrete floors, brick side walls and plank covers. Theheating pipes extend north from the power house a distanceof 780 feet and south 890 feet. They carry a pressure of 30pounds per square inch. All of the condensation, except thatfrom the heaters themselves, is returned to the boiler househot water tank. The steam piping was put in by Messrs. IsaacCoffin & Co., of Boston. By returning to the plan of the pi
