The Cog Railway by ChadSteve1975
The Railway runs from the Lauterbrunnen Valley up to the top of the world.
Depending on the number in your group tickets cost somewhere over 100 euro to go. It aint cheap.
The train stops 2 times inside the mountain enabling great views of the glaciers going down the mountainside
