. Railway master mechanic [microform] . is oneof the fastest lines of communication between the two maintenance of the rolling stock and the manufactureof both freight and passenger cars is carried on at theseshops. A three-phase, 220 volt, 60-cycle, system of distribu-tion is employed with constant speed induction motors. The original electrification was begun about six years agoby the installation of a 75-kilowatt, belted generator whichwas used only for lighting purposes, and about one year latera 125-kilowatt Westinghouse generator was added to supplypower for the machine shop.

The original electrification was begun about six years agoby the installation of a 75-kilowatt, belted generator whichwas used only for lighting purposes, and about one year latera 125-kilowatt Westinghouse generator was added to supplypower for the machine shop. This is in use at present andis driven by a Ball engine of 225 horsepower capacity, directconnected to the generator. Upon the erection of the newplaning mill it was necessary to replace the 75-kilowatt gen-erator by one of 150 kilowatt capacity to drive the wood-working machines. This latter generator is direct connectedto a Ball engine of 250 horsepower capacity. The generatorsare excited from a lT^-kilowatt, 125-volt, direct-current. Westinghouse generator driven by a Troy upright larger generating unit and the exciter are shown inFig. 1. Steam is supplied from two locomotive type boilersat 125 pounds pressure. The entire electrical equipment was installed by the localoperating force of the company under the direct supervisionof Mr. W. F. Kapp, superintendent shops and the time of the original installation no interferencewhatever has been experienced by the failure of any of thepower plant equipment or the motor, the only interruptionof service which has occurred has been the occasional blow-ing of a fuse when some one of the motors was started im-properly. The switchboard, shown in Fig. 2, has two generatingpanels, one exciter panel and two feeder panels, all of blueVermont marble. Ammeters are provided for all three legsof the circuits on each generator panel, with a voltmeter foreach generator as well as a voltmeter and ammeter for theexciter. Wh
