[1] The North Western Railway (NWR) is the main standard gauge rail network on the Island of Sodor.
Beyond Skarloey, the line continues to a former slate quarry, later used as ammunition dumps.
The railway is owned by Sir Handel Brown, who serves as its chairman, and is run by Mr. Roger Sam, the son of the previous controller, Mr. Peter Sam.
It climbs to the top of Sodor's highest mountain, which shares the railway's name.
It is based on the Snowdon Mountain Railway in North Wales, was opened in 1900 and for many years was operated under the direction of Mr. Walter Richards, the General Manager.
