Flamsbana is touted as one of the most beautiful train journeys in the world. From their own website: The train journey runs through fantastic nature, past the Rallar road, steep mountains, breathtaking waterfalls, through 20 tunnels and offers so many viewpoints that many feel like travelling multiple times between the mountain and the fjord. In the span of a single hour, the train takes you from the ocean level at the Sognefjord in Flam, to the mountaintop at Myrdal mountain station on Hardangervidda, 863 meters over the ocean.
