WD Stanier 2-8-0 307 → 70307 → 500 → BR 48773

LMS Stanier Class 8F No. 8233, War Department Nos. 307, and later 70307, Iranian State Railways No. 41-109, Longmoor Military Railway 500, British Railways No. 48773, is a preserved British steam locomotive. Its owners claim that it is "possibly Britain's most travelled preserved locomotive". Construction and use by the LMS 8233 was originally built in 1940 by the North British Locomotive Company of Glasgow, Works No. 24607 on the orders of the War Department, which had adopted the LMS Stanier Class 8F as its own standard. However, the Fall of France saw that it was not sent to mainland Europe with the British Expeditionary Force, as originally intended. Instead, it became LMS No. 8233 and was based out of Toton, Holbeck and Westhouses sheds. Export In 1941, No. 8233 was requisitioned by the War Department and sent to Persia (Iran), becoming Iranian State Railways No. 41-109, during which time, it derailed following a collision with a camel. In 1944, it was converted to oil-firing. In 1948, it was at Suez needing a new firebox and was almost scrapped, but was then returned to England in 1952 and overhauled at Derby Works. In 1954, the engine was no longer needed in the Middle East and went instead to the Longmoor Military Railway as WD. No. 500. British Rail and withdrawal In 1957, No. 500 was taken into British Railways stock as No. 48773. It was initially allocated to Polmadie (66A), and was withdrawn from there in 1962. However, it was reinstated in 1963 and transferred to Carlisle Kingmoor (12A). It was then transferred to Stockport (Edgeley, 9B) and Buxton (9L, though perhaps only on paper), and then to Bolton (9K) in September 1964. With the end of steam approaching, No. 48773 was transferred to the North West, moving to Rose Grove (10F) in July 1968. It worked its last main line train on 4 August 1968.
