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

Ten more minutes to go down to the station in Wengen. You see one of the trains of the Grindelwald-Wengernalpbahn above the small road I walked down to the station

You find more information about the gauge rack railway line in
