In 1888, Frank J. Sprague built the first successful electric-powered trolley car system in Richmond, Virginia. A few years later he invented multiple-unit control, an innovation that allowed the creation of heavy electric elevated and subway systems.

The motormen and conductors who operated these trains, trolleys and interurbans were often trained using Sidney Aylmer-Small's How to Become a Successful Motorman. This book contains information regarding the Dynamo, the Motors, Systems of Control, Trolley and Third Rail Lines, Rolling Stock, Air Compressors, Multiple Unit Control, Automatic Air Brakes, Rules and Regulations and Examination Questions for Motormen. 335 pages.
