From The Rough Guide to Scandinavia:
… the Flåmsbana, a twenty-kilometer, 900-meter plummet down the Flåmsdal valley to Flåm – a fifity-minute train ride that should not be missed if at all possible…
… the track, which took four years to lay in the 1920s, spirals down the mountainside, passing through hand-dug tunnels and, at one point, actually travelling through a hairpin tunnel to drop nearly 30m. the gradient of the line is one of the steepest anywhere in the world…
I really, really, want to do this ride.
I want to do it too!
