GWR 4900 Class 5972 Olton Hall

5972 Olton Hall is a preserved Hall class 4-6-0 steam locomotive of the Great Western Railway, made famous for hauling the Hogwarts Express in the Harry Potter films. It was built at Swindon Works in April 1937 and first allocated to Carmarthen in South Wales, where it stayed until 1951, then moved to Plymouth Laira after being fitted with a three-row superheater and finally to Cardiff East Dock. It was withdrawn in December 1963 and sold to Woodham Brothers at Barry for scrap in May 1964, was bought by David Smith in 1981, and was restored at Carnforth, steaming again in 1998. For the films it carried a Hogwarts Express headboard, a crimson livery and Hogwarts Castle nameplates, and pulled a rake of British Rail Mark 1 carriages, which led to the joke of the Hall that thinks it is a Castle. It also worked excursions such as the Shakespeare Express and two final Wizards Express rail tours in 2014, and since 2015 it has been on static display at the Warner Bros Studio Tour near Watford.
