Late in automn I walked from Grindelwald to Wengen crossing the Kleine Scheidegg, more or less following the Grindelwald - Wengernalpbahn.

Here is a view from station Allmend (on the right side of the panorama) down to Wengen. Far away you might see a train.

You find more information about the gauge rack railway line in
