The biggest star of the Harry Potter movies is coming to Cheltenham.

The dark red steam locomotive that hauls the Hogwarts Express - all 76 tonnes of it - is being lent to volunteer-run Gloucestershire Warwickshire Railway for eight days.

During its stay train fans will be able to enjoy a ride between Cheltenham Racecourse and Toddington stations.

GWR commercial director Malcolm Temple said: "This is probably one of the world's most famous steam trains, as it has appeared in all of the Harry Potter films, which have been seen by millions in cinemas all over the world.

"It really is a unique chance for visitors to see this magical engine in all of its red and steamy glory – and to ride through the Cotswold countryside in a train pulled by it. But it's much more than just a train ride – it is a journey into the imagination.

"Although the locomotive has worked public trains on the main line, this is the first time the engine has operated services on a heritage railway for families to enjoy, and we are thrilled that the GWR is where this is happening."

The locomotive will first appear at GWR's 25th anniversary Cotswold Festival of Steam from May 23 to 26.

It will then tow ordinary GWR trains between Toddington and Cheltenham on May 27 and 28, and over the weekend of May 30 and 31.

Prices for the festival start at £10 for children aged five to 15 and £14 for adults. A family ticket for two adults and three children costs £34. All tickets allow unlimited travel on the trains for day on which they are issued.
