I remember seeing the film years ago…..think I recorded it on VHS just to put it into context as to how long ago that was….
From memory there was a classic case of no continuity of one of the freight trains in the film, with the first shot showing a pannier on the front, then a 66XX and the last shot some other copper capped chimney machine at the head of it.
Story line was pretty weak, but as stated above, some really good views of the GWR in its prime.
Cheers,
