The Wengeneralpbahn, a cogwheel train, is the longest through train in the Jungfrau Region. It links Lauterbrunnen and Grindelwald with the Kleine Scheidegg. Since 2005, three modern Niederflur-Panorama trains with a capacity of 152 seats each have been in operation.

The most traveled stretch is Lauterbrunnen-Wengen, which also handles the freight for Wengen, a car-free resort.

In times of heavy traffic, additional trains can follow the regularly scheduled train in quick succession. This way the capacities can be optimally adjusted to fit need.
