I am another for the original ''The Ladykillers'. This was the railway and North London of my childhood. As a modelling resource of visual references only the DVD would be strongly recommendable; and it is a very funny story.
From over the pond, 'The General'. Buster Keaton, and antics with the steam railway. Some of the stunts verge on the unbelievable, simply for the degree of hazard involved. The detail of the cab interior, the rock and roll ride, and the general railway background make it doubly interesting.
