Runaway Railway (1966)

A hybrid of The Titfield Thunderbolt and The Great St Trinian's Train Robbery made for children in 1966, you say? With Ronnie Barker and Jon Pertwee in the cast? Count me in.

Pertwee is not the film's only link with Doctor Who. Among the child actors is Roberta Tovey, who appeared in the two films in which Peter Cushing played the Doctor.

Sadly, I did not see Runaway Railway when Talking Pictures TV screened it as part of their Saturday morning pictures the other day, but I was alerted to it by a Twitter thread from Tim Dunn.

There is a short article on the film with stills on the Obscure Train Moves blog and you can enjoy the first few minutes above.

Then you can watch the whole thing online, but I didn't tell you that.
