The history of electric freight and inter-urban commuter locomotives in the U.S. begins with their development in East Coast urban centers and continues their service in the present day. Railways that used or continue to use electric motive power in cities, suburbs and even over mountain passes - including the B&O, Pennsylvania, New Haven, New York Central, Norfolk & Western, Illinois Central, Milwaukee Road, and Amtrack - are depicted in period and modern color photography. This book also covers legendary electrics like the S-motors that towed steam powered trains through tunnels and into busy urban stations and several more. The text includes discussion on the roles played by GE and Westinghouse, specialized equipment, and how technology laid the groundwork for the development of diesel-electric locomotives prior to WW II.
