Thomas & Friends (previously known as Thomas the Tank Engine & Friends) is the name of the television series based on the Railway Series by the Reverend W. Awdry. It was adapted for television by Britt Allcroft using the original stories from the Railway Series before using television-exclusive stories written by independent writers.
Thomas & Friends is 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. The head of the North Western Railway is Sir Topham Hatt, affectionately nicknamed "The Fat Controller" by the engines and staff and the Skarloey Railway is operated by Mr. Percival, "The Thin Controller".
