Wengernalp railway, railway line in Switzerland

The Wengernalp railway is a narrow-gauge rack railway running through the Bern Alps, connecting towns like Grindelwald, Wengen, and Lauterbrunnen to the mountain station Kleine Scheidegg. The line spans about 19 kilometers through forests, meadows, and steep mountain terrain with large windows on modern trains allowing clear views throughout the journey.

The railway was built to connect isolated mountain settlements and support tourism in the Alpine region. Over decades, it became one of the world's longest cogwheel railways and remains a vital part of Switzerland's historical mountain transportation systems.

The line is named after the Wengernalp meadow between Wengen and Kleine Scheidegg. Wengen has no generally accessible road, so the train is the principal means of access, and the railway also carries freight; Wengen station was rebuilt in 1995 with a freight delivery terminal. Trains run in two sections, and most passengers change at Kleine Scheidegg for the Jungfrau Railway.

Trains run in two sections, both ending at Kleine Scheidegg, where you change for the Jungfrau Railway to Jungfraujoch. The locomotive is always on the valley side, so seats face a mountain side and a valley side. Between Lauterbrunnen and Wengen, only Swiss general passes such as the GA and Swiss Travel Pass are valid.

The right side of the train offers the best views of the mountains and valleys on both sections of the journey. At Wengen, one of the villages along the route, visitors can experience a true car-free mountain village where the railway is the only way to transport goods and people.
