Mountain railway

A mountain railway is a railway that operates in a mountain region. It may operate through the mountains, for example by following mountain valleys and tunneling beneath mountain passes. Or it may climb mountains, in order to provide transport to and from their summits.

Mountain railways often, but by no means always, use narrow gauge to allow for tight curves in the track and reduce tunnel size and structure gauge, and hence construction cost and effort. Where a mountain railway needs to climb steep gradients, it may use steep grade railway technology, or even operate as a funicular railway.

The Culdee Fell Railway is featured in the book Mountain Engines, part of The Railway Series by Rev.W.Awdry.
