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 Valley to the Jungfraujoch could be realised without disturbing the unique landscape of the UNESCO World Heritage site.
