They Had an Idea(1953)

In every industry men still need skill and knowledge, but the addition of a dash of imagination will often mean more pleasure from the job as well as greater efficiency. The film presents four examples: the invention of a ratchet device for turning rails; reshaping worn spanners at a locomotive works; speeding up the replacement of old escalator slats by means of an attachment to a drill; and finally, the thoughtful porter working at a country station who goes out of his way to warn a regular passenger of a change in the timetable.
