Each quarter, Statistics Norway produces figures showing the number of journeys on various modes of public transport, as well as revenues generated.
The figures for the final quarter of 2014 have just been published but we thought it would be useful to look back over the past decade.
The chart shows that both revenues and passenger numbers had been moving largely in step for the early part of the past decade, but the revenues have grown more sharply in both 2012 and 2013.
This trend has continued into 2014. The latest figures available show that revenues year-on-year in the final quarter of 2014 were 5.5% higher than in the final quarter of 2013; passenger numbers meanwhile, were up just 0.7%.
This suggests that rail fares in the country are increasing on average.
The Norwegian rail network is separated between infrastructure - which extends more than 4,000 kilometres – and operating companies. The key companies involved are the state-owned Norges Statsbaner, NSB Anbud, CargoNet and Flytoget as well as Hector Rail, Tågåkeriet and Ofotbanen.
The growth in passenger numbers comes against a backdrop in growth in capacity: train services on the Trønderbanen have been expanded and there are extra services on the Sørlandbanen and the Salten Commuter Line, while extra seats have been added to services in Eastern Norway. New Flirt trains are being added to the fleet and these have extra seats.
