PARTS of a keenly-awaited new film version of a classic of children's literature were filmed on the Keighley & Worth Valley Railway.

The adaptation of Arthur Ransome’s book Swallows and Amazons will be released across the country on August 19.

Railway scenes for the film were shot on the K&WVR in July last year, but the identity of the feature film was then a closely-guarded secret.

The attraction was contractually forbidden from publicising the details of the film until now.

K&WVR filming liaison officer Roger France said: "I was lucky enough to be invited to the world première of the film in Keswick on July 24.

"As a classic children's story there are obvious parallels with The Railway Children, so we are particularly delighted that the K&WVR will also be associated with this production as well."

The novel Swallows and Amazons was first published in 1930.

It follows the experiences of four children dreaming of escape from the tedium of a summer holiday in the Lake District with their mother.

When they are finally given permission to camp on their own on a remote island in the middle of a vast lake, they are overjoyed.

But when they get there they discover they may not be alone.

As a desperate battle for ownership of the island ensues, the real dangers of an adult world on the brink of war encroach on their paradise.

The cast of the new film adaptation will include Rafe Spall, Kelly Macdonald and Andrew Scott.
