Late in automn I walked from Grindelwald to Wengen crossing the Kleine Scheidegg, more or less following the Grindelwald - Wengernalpbahn.
On this panorama you can see a train going up to Kleine Scheidegg. Next stop will be Alpiglen. On the left side you can see the station Brandegg. A train just left the station going down to Grindelwald.
You find more information about the gauge rack railway line in
