Rack railway
A cog railway or rack railway is a steeply inclined railway with a special rack rail mounted in the middle between the regular rails. The trains are fitted with one or more cog wheels that mesh into this rack rail.
Examples:
- Mount Washington in New Hampshire, built in 1869, the only railway in the world built entirely on a trestle (3.1 miles or 5.2 km long).
- Manitou and Pike's Peak Railway, Colorado Springs, Colorado, United States
- Jungfrau Joch, on the border of the cantons of Bern and Valais, Switzerland
- Schneebergbahn, Lower Austria, Austria
