While he was passing lock No. 4 Mr Monkey heard a rumbling noise. He peered over a wall and found that he was standing on top of a railway tunnel. This took the line from the viaduct - where it was 13 feet above the canal - under the canal and on to Marple station. It was tunnelled 65 years after the canal was built, without breaking the canal.
