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

I am almost down in Wengen. The railway line is a little bit above the first houses of Wengen and you might see a train going down to Wengen.

You find more information about the gauge rack railway line in
