Opened on 21st August 1895 this line was built as an extension to the M.E.R. from Laxey to the summit of Snaefell, the island’s highest mountain. Due to the steep gradients (1 in 12) the line uses the wider 3′ 6″ gauge with a fell rail in the centre for additional braking and runs on the right. The car works and depot (the original structure was replaced in Centenary Year 1995) are situated just above the Laxey terminus but major overhauls are carried out at Derby Castle. For this the cars have to be placed on to temporary bogies. The rolling stock on this mountain railway is very similar to M.E.R. cars 10-13 (long since gone from the fleet) with two bow collectors.
