Old steam engines are broken down for scrap and used to make new ones at Swindon.
Various shots of old steam engines being broken down into scrap metal at an engine yard. Several men work with axes to break down one engine - looks like hard and slow work! Piles of parts from the old trains lie around. A large electrically-powered magnet crane lifts a huge steel girder; when the current is switched off the girder falls to the ground. The final shot shows a brand new steam engine, apparently made from the scrap from the old engines.
