Magnetic Lofty Bob the Builder : Season 3 Episode 4

Mr Bentley has organised some town improvements. Wendy is to turn an old railway line into a cycle path and Bob is to turn an old rubbish dump into a park. Lofty has been equiped with a magnet to remove the old rails. Lofty's magnet comes in useful to search for Mr Bentley's pen. Bob then recycles the old sleepers and rails into a park bench.
