Actually, for me, that was probably the most ridiculous scene of what was a pretty good drama. I'm sure half the viewing population were shouting "let go of the dead man's handle!". The robbers did have a try at driving an engine in a shunting yard but Reynolds' chance encounter with Biggs (with his engine driver contact) seemed to solve the problem. 1963 had a bad winter and a poor summer but I doubt there'd have been snow on the ground by the time they went engine driving.
