An incompetent teacher is sent into Nazi Germany to steal a secret weapon

The climax to this comedy features a barnstorming plane ride that includes a short flight along a railway line, in this case the former LSWR main line between Basingstoke and Woking. The plane, through some clever editing with a model and the use of back-projection, narrowly avoids a collision with an express hauled by a ‘Lord Nelson’ Class 4-6-0. Moments after this, there is a very brief glimpse of a much older 4-4-0 design on a passenger service.

The model Luftwaffe aircraft flies along the railway line almost at ground level!

The terrified crew in the aircraft look out of the cockpit to see this express train bearing down on them
And this closer view shows the loco to be a ‘Lord Nelson’ 4-6-0 and that the shot is reversed. The number on the bufferbeam is largely obscured by steam, but might be 854 Howard of Effingham.
As the plane rises to avoid a collision the location has changed completely, as has the train. The latter is just about visible on the right and appears to be a local passenger service hauled by a 4-4-0 locomotive.
