Mystery Tour is a magazine story.
Passengers are boarding Arthur's "Mystery Special". They are all very excited, except Arthur; he had been pulling the special all week. Each time, he went on the new line to the Fishing Village and he was getting fed up with the same, old scenery. Then there was trouble on the track and Arthur was diverted onto another route. This time he passed the canal, the Windmill, and a castle before returning to the main station. The passengers enjoyed the mystery tour and so did Arthur - it was a mystery for him too.
