The plot is hackneyed, even for the period, and the pace plodding. However it does have some fascinating, documentary-quality external shots of steam locos, railway stations, bridges and rivers, etc., often filmed in a pleasingly 'noir-ish' style and, if nothing else, must still be of interest to transport enthusiasts and post-war historians. In contrast, the studio filming looks extremely flat and conventionally composed. It would be interesting to know who the second unit director was.
It is also of some interest to see Christopher Lee in an early role although, as usual, he is woefully underused.
