December, 1907 AMERICAN ENGINEER AND RAILROAD JOURNAL. 489 ELECTRIC SWITCHING LOCOMOTIVE. Large manufacturing plants having a number of buildings cov-ering considerable area have found it necessary to build andequip switching railroads within their own confines. Whereelectric power is convenient and cheap, or for reasons of cleanli-ness, noise, etc., it has often been found advisable to electricallyequip these roads using small electric locomotives for handlingtrains of either narrow or full gauge cars. The Cerveceria Cuauhtence Brewery of Monterey, Mexico, isa plant of this kind, and the 25-ton electric switching locomo-tive shown in the accompanying illustration has been purchased. ».-«,- ELECTRIC SWITCHING LOCOMOTIVE. of the Jeffrey Mfg. Co., of Columbus, O., and put into operationat that point. The switching locomotives built by this companyare of the same general type and take the same electrical equip-ment as its well-known electric mine locomotives. The onlychanges made in the illustrated case are in the side and endframes and the addition of the platform and a suitable cab. Thislocomotive has two motors of the water-proof type, with drumwound armature and laminated pole pieces. Locomotives for this service are being built in sizes from 10to 30 tons, with two motors, and in larger sizes with 3 and 4motors. These are arranged with rigid frames or with doubletrucks having a flexible wheel base, as conditions may requre.
