Gently does it as Olton Hall - the engine that stars as Hogwarts Castle in the Harry Potter movies - is eased from its road transporter at the Gloucestershire Warwickshire Railway's Toddington station after a long journey by road from its Carnforth, Cumbria home.

The engine is set to star in the 25th Anniversary Cotswold Festival of Steam on the GWR Honeybourne Line from next Saturday to Tuesday, 23rd to 26th May when it's sure to attract muggles from miles around.

This is the first time that Olton Hall, in its red Hogwarts Railways livery, has worked passenger trains on a heritage railway.  Malcolm Temple, the all-volunteer railway's commercial director, says: "This is a really magical moment for us - to have what must be the world's most famous steam engine film star on our railway is a great privilege. 

"Over the next couple of weeks there will be plenty of chances to travel into your imagination on trains pulled by this 80-ton film star!"

Olton Hall - better known as Hogwarts Castle - is performing with seven other steam locomotives over the four-day festival.  It is then working to a special timetable on the GWR on Wednesday and Thursday 26th and 27th May  and then normal trains on Saturday and Sunday, 30th and 31st May.
