Speaking of Freight (1961)

When a business tycoon allows himself to be 'snared' into seeing some films in a railway traffic manager's office, there must be a reason for it. In this case, it's a particularly giant-sized transport problem. But before he's convinced that the railways can help him solve it, there is an atmosphere of battle in the room, and some interesting and unexpected facts are hurled about in the course of the argument. Made to promote the use of railways to transport raw materials and finished products.
