Locomotives of this class were often referred to as a "Mickey Mouse". It is a 2-6-0 'Mogul', rated 2MT by BR following nationalisation. No 46521 was one of the final batch of these locomotives built by BR at the Swindon works in 1953. The Swindon batch incorporated certain modifications over the earlier versions including an increase of ½in cylinder diameter, blast pipe modifications and a taller chimney. 46521 had a working life with BR of just 13 years, based around the Cambrian area where it carried BR Green livery fully lined out in orange and black.

In October 1959 returned to Oswestry, and in March 1963 was allocated to Machynlleth, before undergoing a heavy overhaul at Crewe between 30 April and 1 June 1963. Following that overhaul, the locomotive was involved a three-day visit to North Wales by the in August 1963, its duties being positioning moves and overnight steam heating of the Royal Train stock. 46521 did not run many more miles before being withdrawn by BR in November 1966 and moved to Barry Scrapyard in March 1967.
