The book opens with a very interesting chapter on the predecessor horse drawn lines which were then succeeded by the electrified Harrisburg City Railway and the East Harrisburg Railway. The book examines the operation of the streetcar companies, including the Harrisburg Traction Co., the operational and financial difficulties, and the transition to bus service that became complete after the 1937 Susquehanna River flood. With chapters on the rolling stock (including paint schemes), routes, parks and buildings, and even a chapter on the ill-fated Middletown Electric Railway. Illustrated throughout with black and white photos.
