They provide essential transportation links for remote communities and are also popular for scenic tourism. Mountain railways can be found in various parts of the world, including the Swiss Alps and the Rocky Mountains. They offer breathtaking views of natural landscapes, making them a favorite among travelers. Many mountain railways are historic, showcasing engineering marvels from the past.
