what is the number on the hogwarts express
GWR 4900 Class 5972 Olton Hall When filmed, Olton Hall carried a "Hogwarts Express" headboard on the smokebox, featuring the Hogwarts school crest. The same emblem is featured as part of the "Hogwarts Railways" sigil on the tender and carriages. It retains its GWR number of 5972, but with alternative nameplates fitted, naming the engine Hogwarts Castle. It is painted in a crimson livery â€” a non-standard colour, as Great Western Railway locomotives traditionally used green.
