Prototype heavy freight locomotive 7200 became the last steam engine to depart the remnants of the world famous Swindon works on 12 December 2006, following extensive refurbishment in Steve Atkins's Heritage Engineering Workshop.

7200 was originally constructed as a 2-8-0 Tank no. 5275 and used for heavy coal trains. When the demand for coal fell off the engine was enlarged to the 2-8-2 Tank formation so it could usefully work all over the former Great Western main lines with, being seen in the Midlands, South West and London areas, though mainly operating in South Wales. She is the prototype of a class of 2-8-2 Tank Locomotives. The first 20 of the re-modelled locomotives were so successful that another 34 were similarly re-built.
