British Railways Diesel and Electric Locomotives

In this book, Longworth covers in detail all the classes of diesel and electrics locomotives that were introduced by BR from the modernisation plan of 1955 to the present day. Each class, which operated over this lengthy period, is covered inside. The headlong rush to eliminate steam traction and modernise the railways from the 1950s onwards produced very mixed results. Some of the locomotives introduced were highly successful and long lived with examples still in service well into the 21st century whilst others were found seriously wanting and withdrawn completely after only a few years in service. For each class, a concise history is provided giving construction details and full technical specifications. For every individual locomotive, a full listing is provided including all numbers applied throughout its career, names where they were allocated, details of entry into service, full allocation details over their operational life as well as withdrawal and scrapping dates.
