Since the 1800s locomotives have steamed, chugged and sparked their way into the nation's affections. These powerful engines were the drivers of the Industrial Revolution, and to the present day carry passengers and freight to every corner of Britain. But do you know your Locomotion from your Rocket, or your Gresley Class A4 from your Princess Coronation Class? How heavy is the Flying Scotsman? And who designed the Britannia Class? The Loco Spotter's Guide answers all of these questions, with first-class illustrations portraying more than 60 of the most important steam, diesel and electric designs, including all-important specifications and technical details to aid any would-be loco spotter.
