Mount Rigi Railway
Mount Rigi actually boasts two branches of a mountain railway - one running from Vitznau, and the other beginning in Arth. The Vitznau branch was actually Europe's first mountain railway, having run its first train to the summit in 1871.
The line was extremely popular, and there was enough demand to build the second branch from Arth, which opened in 1873. Both lines are less than five miles in length, and both offer stunning panoramic views of the Alps. Although parts of the railway were electrified in 1906, steam traction is still occasionally used on special weekends.
