around the 1500-600 volt automatic relay. The protection of the locomotive against short-circuitincludes one main fuse for the trolley circuit, two fusesfor protecting locally the circuits of the pairs of motorsand smaller fuses for the auxiliary circuits. The mainfuses are of the copper ribbon type and are fitted withhinged covers to facilitate fuse renewals. All fuseboxes have magnetic blow-outs, energized by currentpassing through the fuse to insure proper rupture ofthe arc. The main fuse box is placed as near as possibleto the overhead trolley to protect the wiring circuitsnear the source of supply. An aluminum-cell lightningarrester is also installed in the cab. The locomotive is equipped with standard luminousarc headlights fitted with semaphore lenses. The brack-ets and plugs are arranged so that one headlight may beinstalled on each end or two on either end as desired.Trolley retrievers are used lor the pole collectors, andthe edge of the cab roof has projecting guard rails to

Piedmont 1500-Volt Locomotive—Motormans Cab Showing Operating Equipment and the Location of Apparatus at No. 1 and No. 2 End, Respectively the engineers seat, controller, air-brake valves, bell andwhistle ropes, ammeter, air gages, sander valves andother parts of the control apparatus that should be with-in immediate reach of the engineer. A tool box is alsoprovided. Current is collected by an overhead US-13 pantographtrolley, which is pneumatically controlled and can beput into service from either engineers station by amanually operated valve. The trolley is arranged fora minimum operating height of 14 ft. 6 in. and a maxi-mum height of 22 ft. On local lines where the overheadconstruction is not adapted for the pantograph trolleythe locomotives use pole-type trolleys and trolley wheels.Some of these local lines are operated on 600 volts andeven 500 volts. A change-over switch is installed to cutout the dynamotor while the locomotive is operating onlow-voltage circuits, so that in s
