motives is presented:In 1880, Edison ran a number of experimental locomotives at MenloPark with power from a dynamo. The 1880 locomotive is now at Brook-lyn Polytechnic Institute. In 1882, Henry Villard, President^ of theNorthern Pacific R. P.., contracted for an electric locomotive for freightservice in the Dakotas. It was equipped by Edison with a series belted220-volt, 10-h. p. motor and hauled three-car trains, power being suppliedthru the two track rails. Hammer, in Elec. World, June 10, 1899, andElec. Review, July 23, 1910, gives photos, drawings, and maps. In 1883, Edison, Field, Mailloux, and Rea operated a geared andbelted 3-ton electric locomotive, The Judge, using a third-rail con-tact line, over 1550 feet of track at the Chicago Railway Exposition andat the Louisville Exposition.

In 1884, Daft operated locomotives and coaches, in experimental work,on a 2-mile road between Baltimore and Hampden. The motors on twoelectric locomotives were a 130-volt, direct-current type. The gearingused was single-reduction, with cut steel pinions and cut cast-iron gears.The third rail was used, also an underground trolley. Horatio A. Fosterinstalled the equipment. Elec.
