An old television series of children's classic The Railway Children, filmed on the Keighley and Worth Valley Railway, has been released on video for the first time.

Two years before the railway opened to the public it was used as a location for the black and white TV series.

Nick Bennett, chairman of K&WVR, is looking forward to seeing how the railway and its engines looked back in 1968.

He said: "I thought the series was lost forever. We wrote to the BBC a few years ago and suggested they might screen it again, but they didn't think it was of high enough quality."

The series was among the first of many TV and cinema productions to be filmed on the line. The railway's first booking was for a TV advert.

Appearing in the TV series is the locomotive No 957, which re-entered service on the Worth Valley line this year after a long-term restoration. It wore the livery of the Great Northern and Southern Railway for its appearances in both the TV series and the 1970s classic film of The Railway Children.
