"Hogwarts Castle" at Toddington on the Gloucestershire and Warwickshire Railway at their 25th Anniversary Gala. This is the actual loco used in the Harry Potter movies. It is actually an ex-Great Western Hall Class lco named Olton Hall. Normally a resident at Carnforth this loco is a guest at the Gala and very popular with families. This is the first time the engine has worked on a heritage railway.
