Built between 1962 and 1968, the British Rail (BR) Class 47 Co-Co Diesel-Electric locomotive was once the most numerous class of mainline diesel in Britain with 512 examples. 310 locomotives were constructed by Brush in Loughborough, and the remaining 202 at Crewe. The locomotives were used for passenger and freight operations. In 2020, 24 of the class remain operational on the national network with more in storage and an additional 31 preserved. Built in March 1964 BR 47813 was on of the last Class 47/4 locomotives built and as such was one of the group upgraded with additional fuel tanks for extra range. As a result of this added flexibility the upgraded locomotives have been well looked after. No. 47813 has operated under BR, First Great Western, Cotswold Rail, Rail Operations Group (ROG) and most recently Direct Rail Services. This model depicts the locomotive during its ROG tenure.
