Nearby: I think that this picture was not shot in Lauterbrunnen, but in Grütschalp.

It is Grütschalp

This train is originally from Aare Seeland Mobil. It was transported, partly by road, to the BLM because there is no riallink between Lauterbrunnen BOB and the BLM other than a funicular. See a news-clip from Swiss TV.
