A Funicular Railway is just that, fun. Also known as an inclined plane or cliff railway, a funicular railway normally solves the problem of transporting people up extremely steep slopes. They’ve been used for hundreds of years and are an extraordinary feat of ingenuity.
How it Works
Conventional trains, using steel wheels on a steel track, could never efficiently climb a track as steep as most funicular railways. Steel wheels are used to decrease rolling resistance, which improves the efficiency of trains on flat ground, but would hinder their ability to get traction going up steep slopes.
The Incline Railway, and funicular railways in general, solve this problem by pulling trains up steep grades with a cable. With this cable, the steel wheels don’t need to have traction, but can be used primarily to guide the train along the tracks. The funicular railway is made even more efficient by counterbalancing two train cars on the same track and using the weight of one to help pull the other up the mountain. The Incline has two cars that ride on the same single mile-long track. When the cars come close together, the track splits into two as a “passing loop” for both cars to pass one another. This single track, passing loop system, is used in funicular railways across the world!
Funicular derives from the Latin word funiculus, which translates to “rope”. That’s what they used to be made from! There were rope cables in the funicular loop system powered by either humans or animals. The oldest known funicular is in Hohensalzburg Castle, and it’s known as the Reisszug. Though now being run by a metal cart, cables, and an electric motor, the Reisszug has been in operation since the early 1500s!
The Incline opened in November of 1895 and was constructed by John Crass and the Lookout Mountain Incline Railway Company. The cars originally operated on coal-burning steam engines, which were upgraded to two 100-horsepower motors in 1911. The Incline Railway has been transporting eager passengers up Lookout Mountain for over 125 years!
