Both resistance and motor cables are of No. 00extra flexible flame-proof wire. This wire is considerably inexcess of the required capacity, but the company has foundthe use of extra heavy wire very desirable, in that it insuresagainst overheating of cables under almost all circumstances,and this reduces the fire risk to a minimum.

One motor, mounted on each truck,is placed on the inside axle. Westinghouse mo-tors known as style No. 121 of 75 hp each areemployed, and the general type to which they be-long was described at some length in the Journal for Sept. 23, 1905. The frameis split at an angle of 45 degs. The armature isusually changed by removing the top half of themotor casing, and this operation requires onlyabout 30 minutes. If it is desired to change mo-tors rather than armature, the motor may be liftedfrom the truck by simply removing the gear caseand the axle caps. The brush holder consists of two parts, thatholding the terminal, which is bolted to the motorshell, and the carbon holder, which in turn is se-cured to the terminal holder and is so designedthat as the commutator wears down it can be low-ered, while the terminal hold
