Nerobergbahn

The Nerobergbahn is a funicular railway in Wiesbaden, Germany. The line links the city, with a station at the north of the Nerotalanlagen, with the Neroberg hill to its north, which offers a panorama view.

History
The line opened in 1888, and is one of the few funiculars employing water propulsion. At the upper station, tanks on the downhill car are filled with up to 7000 L of water to ensure that it is heavier than the uphill car. The downhill car then pulls the uphill car uphill with a 452 m long steel cable. When the downhill carriage arrives at the lower station, the water is discharged and pumped uphill.

In 1939, it was planned to convert the line to electric propulsion and to provide larger cars, but the outbreak of World War II prevented this. The line was taken out of service in 1944 due to war damage, and service was restarted in 1948. In 1988 the line was protected as a technical monument by the State of Hesse.
