What's the Difference?
The Bergen Railway (Bergensbanen), operated by Vy (Norway's national rail operator), is the main event: a roughly 7-hour, 371-mile mainline route connecting Oslo and Bergen. The railway climbs from sea level all the way up to 2,800 feet, crossing the Hardangervidda mountain plateau — one of the highest mainline railways in Europe, and a route that passes near Finse, one of the highest stations on the line. The scenery along the way includes glaciers and a wide variety of landscapes, from open tundra to snow-covered plateau, especially enjoyable in winter when everything is blanketed in white. The Flåm Railway (Flåmsbana) is a short, steep branch line — just 20 kilometers — that drops from the mountain station of Myrdal through the narrow Flåmsdalen valley down to the fjord-side village of Flåm, near the town of Aurland. The journey takes about one hour, passing through 20 tunnels along the way. It's one of the steepest standard-gauge railways in the world, and it deliberately operates at slow speeds, which gives passengers plenty of time for photos rather than rushing through the middle of the best scenery.
