Report No. 12 in a series of 13 topical films, produced since the far reaching plan for the modernisation and re-equipment of British Railways in 1955 started to take effect, to log the many developments - new services, equipment, techniques - wherever these have been introduced. They provide a unique pictorial record of the progress of British Railways. Commercial and technical developments on British Rail: new freight loads, air conditioned carriages, an ultrasonic test-train for checking the permanent way, a lecture train, and a new station for motorists - all part of the railway scene in the 1970's.
