2008 Proposals

In early 2008, Jungfraubahn Holding AG announced it is exploring the futuristic idea of an efficient fast form of access to the Jungfraujoch as an addition to the rack railway. A feasibility study has been commissioned. The additional access would be the world's longest tunnel-lift system. The study is to show if and how such a tunnel-lift system - for example as a fast lift or funicular - from the Lauterbrunnen

Railcar
A railcar, in British English and Australian English, is a self-propelled railway vehicle designed to transport passengers. The term "railcar" is usually used in reference to a train consisting of a single coach , with a driver's cab at one or both ends. Some railways, e.g., the Great Western...

es carrying 230 per train which operate at 12.5 km/h on the steepest parts of the ascent. The motors function at two speeds which allows the units to operate at double this speed on the less steep part of the ascent (above Eismeer station).

The motors will operate in a regenerative mode which allows the trains to generate electricity during the descent which is fed back into the power distribution system. Approximately 50% of the energy required for an ascent is recovered during the descent. It is this generation that regulates the descent speed.
