The Wengernalp Railway serves as a gateway from Lauterbrunnen and Grindelwald to the excursion and winter sports area of Kleine Scheidegg and provides access to the world-famous destination of Jungfraujoch – Top of Europe. Its length of 19,114 metres makes it the longest cog railway in the world. The train provides transport for passengers and ensures the supply of goods for the car-free residential and holiday resort of Wengen. Ten modern low-floor panorama trains with a capacity of 152 seats each have been running on the Grindelwald-Kleine Scheidegg route since 2005 and on the Lauterbrunnen-Kleine Scheidegg route since 2014. With the current rolling stock, the travel time from Grindelwald-Grund to Kleine Scheidegg is 24 minutes, and from Lauterbrunnen to Kleine Scheidegg 42 minutes. The trip from Lauterbrunnen to Wengen takes 12 minutes.
The Wengen shuttle, which was introduced in December 2023, helps to increase the attractiveness of Wengen as a lively village. The shuttle runs between Lauterbrunnen and Wengen and is used on days with high traffic volumes. Wengernalpbahn AG also owns the winter sports facilities around Kleine Scheidegg, which have a total of eight chairlifts, and the Eiger Express tricable gondola, which was commissioned in December 2020.
In 1890, the authorities granted the concession for construction of the Wengernalp Railway. The narrow-gauge cogwheel railway to Kleine Scheidegg was opened three years later. The old stretch between Lauterbrunnen and Wengen had a gradient of 250 per mille and was exposed to rock and ice falls, which is why a longer, less steep stretch had been built by 1910. In 2008 and 2009, the old tracks were removed and the terrain partially restored to its natural state.
