While this motor produced considerable power, it was not efficient. In this country, in 1847, Prof. Moses G. Farmer made a car witha motor which looked like a Ferris wheel, only that instead of thecars were iron armatures which were attracted by principle was not substantially different from that of Jacobismotor. It is not necessary to mention all of the early attempts atelectric traction, for until a good source of electric power was devised,all of these attempts were commercial failures. It was in 1879, at the exposition at Berlin, Germany, that a suc-cessful car was shown and operated, drawing a number of trailersfilled with passengers. The car was simply a Siemens motor laidon its side on a little truck and geared to the wheels. Currentwas taken in from the rails. The firm of Siemens and Halske, nowso well known in the electrical business, put a regular ca-r into oper-. 99 4 ELECTRIC RAILWAYS ation in the suburbs of Berlin in 188L In this country, from 1880 to1885, there were many experimenters trying to make electric cars,particularly locomotives. The *names of Stephen D. Field, ThomasA. Edison, Frank J. Sprague, Charles J. Van de Poele, Leo Daft,Sydney H. Short, and others should be familiar to every student ofelectric traction. Finally in 1887, the first large equipment ofelectric traction in this country was installed by F. J. Sprague inRichmond, Virginia, and within a few years the horse, cable, andsteam cars disappeared from the streets. The essential parts of a car are the car body and trucks; themotors and controlling apparatus necessary
