The Mürrenbahn narrow gauge railway of the private BLM is only a less than 5 km long relatively flat railroad high over the village of Lauterbrunnen on a balcony like mountainside near Interlaken. It seems a mystery to the tourist how the Swiss have managed to get the heavy trains up there. This Be 4/4 no. 21 from 1967 has already been used for over 1 million kilometers on a railroad of 4,5 km total. The BLM has three similar trains up there.
