5972 Olton Hall is a preserved Great Western Railway Hall class locomotive that came to prominence in the 2000s when used in the Harry Potter film series to haul the Hogwarts Express. Olton Hall was not the first locomotive to be re-liveried to appear hauling the Hogwarts Express. To promote the fourth Harry Potter book, Harry Potter and the Goblet of Fire, Southern Railway West Country Class locomotive 34027 Taw Valley was temporarily repainted and renamed. However, it was rejected by film director Chris Columbus as looking "too modern" for the film, but it carried the name and colour for some months afterwards.
