«Different international ratings consider the train ride between Oslo and Bergen with the Bergen Railway as the most exciting and beautiful train ride in the world. Last up was Lonely Planet's Tom Hall, who
raved about the Bergen Railway in November 2010, concluding
"The Bergen Line is a journey that will live long in my memory. If you haven't done it you can't say for sure that it's not the world's most beautiful train ride".
No other train ride between two cities in Europe is at a higher altitude than the one between Oslo and Bergen. Linking Norway's two main cities, this line takes in some dazzling scenery, with the most spectacular stretch being the one over the Hardangervidda, Europe's highest mountainous plateau. Finse, at 1,222 metres above sea level, is the highest point on the line. The Bergen Railway is popular with tourists and commuters alike, and serves a number of ski resorts along the way, so it is just as busy in winter as it is in summer. The total travel time between Oslo and Bergen is approximately seven hours. Building work, which started in 1875, took 34 years to complete, an involved a workforce of some 15,000 men. The 182 tunnels were carved by hand. The Bergensbanen celebrated its centenary in 2009.»
