Coupling Procedure
Diesel Multiple Unit Trains


A filmstrip by British Transport Films.

This was an A4 size booklet of lecture notes and twenty-seven 35mm mounted B&W transparencies: a title slide; 24 slides in the main series; a summary of coupling codes; and a credit slide.

They are thought to be taken at Bristol Marsh Junction depot, the paint/brake overhaul dates on the vehicles are late 1970 so this probably dates the series to early 1971.
