The train from Oslo to Myrdal went through wild country, below and above the treeline. It was then a quick change onto the Flåmsbana, a track of only 20km that descends 865m, through about 20 tunnels. Its construction (in the 1920s) demanded some creative engineering: at one point it turns 180° within a tunnel! (see photo; at the upper 'window' the view is to your right, then at the lower 'window' the view is to your left). The construction road is tortuous.
The train stops at this majestic waterfall [also detail with 1/2000s exposure]. In a cringe-worthy display of touristism, they play "traditional" music and a girl in a red dress pops up. Maybe I'm too cynical. In any case, the girl is useful to get a sense of scale.
The only shot I got in Flåm itself was of the substantial river of fresh snowmelt.
The next day I jumped on the ferry going through the Aurlandsfjord and Nærøyfjord to Gudvangen, and back. This is the narrowest fjord in Europe, and I think the peaks rise to about 2000m.
