With almost 7000 new vehicles now being delivered or on order, worth billions of pounds, Britain’s train fleet will change beyond recognition over the next three years. It can be difficult to keep track of everything that’s happening and who has ordered what, but this guide will introduce Britain’s new train fleets, with full descriptions, technical specifications and the routes they’ll work. We’ll also look at the refurbishment and modernisation of existing fleets to meet modern standards, the cascade of trains to boost capacity and improve services elsewhere in the country and say a brief farewell to the life-expired fleets heading for disposal. From high-capacity metro units to state-of-the-art express trains, interurban and regional fleets and luxury sleeping cars, British train operators and leasing companies are overseeing the biggest transformation in rolling stock since the 1950s, as this class-by-class guide will demonstrate. Supported by many behind-the-scenes photographs from production lines across Europe and The Railway Magazine archive, it will be an indispensable guide to Britain’s new train fleets.
