Sinopse
A large group of men are shown performing various tasks in one room at the Westinghouse Air Brake Co. On one side, men are shown pouring a hot liquid into molds on the floor. A conveyor belt delivers items which are then taken off the belt by a man. Men on the other side of the screen appear to be lifting items out of what could possibly be a furnace and putting them on tables. It appears that the men in this room are casting machinery from molds.
