The British Rail (BR) Class 08 is a class of diesel-electric shunting locomotive. The pioneer locomotive, number 13000, was built in 1952 although it did not enter service until 1953. Production continued until 1962; 996 locomotives were produced, making it the most numerous of all British locomotive classes. As of 2011, around 100 locomotives remain working on industrial sidings and on the main British network. On heritage railways, they have become common, appearing on many of the preserved standard-gauge lines in Britain, with over 60 preserved including the first one built.
