"Real?! Of course we're real! We bring all the ballast to put under your track!"
"And wool for making clothes."
"And passengers too!

A map of the railway

The Arlesdale Railway, also called the "Small Railway", is a 15"-gauge railway running from Arlesburgh along the old route of the Mid Sodor Railway to Arlesdale. The ownership of this railway is shared by the Small Controller and the Owner of the Skarloey Railway.

History and Operations

The Arlesdale Railway, runs from Arlesburgh along the old route of the Mid Sodor Railway to Arlesdale. At Arlesburgh, connections can be made between it and the Arlesburgh branch line. Miniature engines, who run on the 15"-gauge track, live and work on the Arlesburgh Railway, and their line is mainly used to transport waste materials from several of the abandoned mines at Arlesdale for use as ballast, but it also attracts popularity due to the novelty of being pulled by a 1/3 scale engine. The engines also transport wool for making clothes.

From Arlesburgh, the line stops at Arlesburgh Bridge Street, Ffarquhar Road, Marthwaite, and Arlesdale Green before turning south to Arlesdale.

The Arlesdale Railway appeared in Small Railway Engines, Oliver the Western Engine, Duke the Lost Engine, Jock the New Engine and Wilbert the Forest Engine, and was mentioned in Enterprising Engines and Thomas and his Friends. It also appeared in various annuals, Railway Series related books and was mentioned in the My Thomas Story Library book, Duck.

The railway made its first television series appearance in Sodor's Legend of the Lost Treasure.
