Between 1860 and 1866, dynamos or electric generators were being HISTORY OF ELECTRIC TRACTION 3 developed; yet it was some time before it was discovered that an electricgenerator could drive a similar machine, now called a motor. In 1867, Moses G. Farmer operated a car with a motor and dynamo. In 1879, Siemens and Halske, at the Berlin Industrial Exhibition,propelled a miniature locomotive and three cars, with electric powerfrom a dynamo. The track rails, 1000 feet long, formed a 160-volt and bevel gears were used to transmit the power from a This demonstration was repeated at Brussels and Dusseldorf,also at Frankfort, in 1881. See photograph in St. Ry. Journ., Oct. 8,1904,p. 536. In 1880, Thomas A. Edison at Menlo Park, New Jersey, ran a smalllocomotive, using power from a dynamo. See section on electric loco-motives in this Fig. 1.—Electric Motor Car and Train. Van Depoele, Toronto, 1884. In 1881, Stephen D. Field ran a large motor car at Stockbridge,Massachusetts, using a dynamo, a positive wire enclosed in a conduit, anda track-rail return. In 1881, Siemens operated cars at the Paris Exposition with currentfrom an overhead slotted tube in which a contact shoe slid, and powerwas transmitted by the motor to the axle thru a chain; and, in 1885, atthe Vienna Exposition, a 150-volt Siemens dynamo supplied current thrutwo insulated rails to a motor in a car. In 1883, Van Depoele built experimental and exhibition lines atChicago, and used an overhead trolley wire, an over-running trolley wheel, 4 ELECTRIC TRACTION FOR RAILWAY TRAINS held in position by ballast, the trolley wheel being connected to the car bymeans of a flexible cable. In 1884, Van Depoele ran an el
