This is one of four volumes covering the history of British Trolleybus systems. This book looks at the networks in Yorkshire. Bradford and Leeds were the pioneering systems in the country and, more than six decades later, it was Bradford that was to the final bastion of this once important form of transport. The author is an authority on tram and trolleybus systems, with a series of books already published on the history of British and Irish tram networks. This volume covers the history and background surrounding the networks looking at the reasons why they were opened and why they eventually closed down.
