Electric cable carIn 1884, the first electrically propelled street-car line in the U.S. was begun in direct competition with horse-cars at Cleveland, Ohio, on the Bentley-Knight system. In the same year, the first practical system in the U.S. of conveying electricity from overhead wires to a motor on the car by a trolley, or small groved pulley on the end of a flexible pole extending above the roof of the car, was made in Kansas City, Mo. Improvements in the apparatus made by Sprague in 1888 led to the first American installation of a large scale electrically propelled street-car system at Richmond, Va. The earliest commercially successful application of electricity to the traction of street-cars was made at Lichterfelde, near Berlin, by Siemens and Halske in 1881.«*[Vol VII, p.776] |
