Calliope

The Calliope used to play music at fairs and somehow became a possession of the Duke and Duchess of Boxford. It was neglected for many years and rusted. Percy and Diesel were told to take the old calliope to the Smelter's Yard, but Percy wants to make it work again. He tries filling it with water and coal and pushing it, but it won't work. The calliope is then taken to the Sodor Steamworks where it is restored.

The calliope plays the original television theme tune.
