Thomas and Friends was a television series mainly based around railway engines that live on the Island of Sodor. The show is mainly about the title character, Thomas, a cheeky little blue tank engine with six small wheels, a short stumpy funnel, a short stumpy boiler and a short stumpy dome. Thomas & Friends takes place on the standard gauge North Western Railway, the narrow gauge Skarloey Railway and the 15-inch gauge Arlesdale Railway.
