The Gantry crane whichserves this storage yard combines the function of unloader,crusher, elevator and distributor. Its efficiency is attestedby the fact that while its normal capacity is considered tobe one 50-ton car per hour, the operators have unloaded a 40-toncar in sixteen minutes, and a maximum of eleven cars (500tons) in a short working day.

The two sections of the generating plant,25-cycle and 60-cycle, are, of course, separated electrically, andeach therefore controlled by a separate switchboard. Twoadditional boards control the rotary converter output for both25-cycle and 60-cycle systems, the latter consisting of a circuit for elevators and other intermittent power. Afifth board controls the exciters. With perhaps the exceptionof the exciters, the generating plant is quite standard through-out. In place
