Robbie is a 13-minute-long film made by British Transport Films in 1979 and revised in 1986. Although it is not strictly a Public Information Film, it is often considered to be so by fans of the genre. The film, which was shown in schools all over Great Britain, is based around a young boy suffering a disfiguring and/or fatal accident when he trespasses on a railway line, with three different versions being made to demonstrate the dangers of both electrified and non-electrified lines. When it was first released, all three versions were narrated and introduced by Peter Purves, later replaced by Keith Chegwin when the films were revised. Robbie was written and directed by Ronald Dunkley and produced by James Ritchie.

We then hear and see a train approaching. The shoelace then pops and Robbie stumbles back in time, but trips on the other tracks; whilst Robbie tries to free his feet off the track we then hear and see another train approaching. Version 2 (overhead electric line): To encourage Robbie to cross the train tracks Robbie's brother Bert snatches Robbie's football boots and throws them to the other side of the track. Unfortunately they get caught on the overhead electric line and when Robbie tries to retrieve them with a long metal pole he is electrocuted. Version 3 (third rail electrified line): Robbie accidentally steps on the electrified third rail and is electrocuted. In the next scene, Robbie's mother is informed that Robbie has been seriously injured, and has had to
