Norges Statsbaner (NSB) operate the national rail service, throughout Norway, including cross-border trains from Oslo to Stockholm (Sweden) and from Narvik in the far north to Stockholm; this service, while entering Norway is operated entirely by Swedish Railways. You can use the NSB online timetable to plan your trip. PDF downloads are available for all NSB Routes in Norway.
A comprehensive list of both passenger and freight operators in Norway can be found on the helpful Railfan Europe website’s Norway page.
A downloadable Railway Map of Norway is available on NSB’s website.
Train times and Tickets
Booking tickets for travel within Norway can be done at stations. Tickets are also available online, information regarding the ticket types, validity and periods available is here. The very handy 24 hour ticket for Copenhagen is excellent value for money. If you only require reservations for either Interrail, Eurail or railway staff passes then this can be done via phone to the DB office in London.
If choosing to use an Interrail pass, either for just within Norway, or to pass through Norway, all the relevant details on the passes, including the different types/lengths of validity available, can be found on the InterRail website.
For those travelling from outside Europe then the Eurail Pass is your ticket to Europe, details of which can be found on EU Rail’s website.
Finally travel in Europe can be made a lot simpler by using the very, very, helpful smartphone app courtesy of Eurail. This app is available both online and offline and is always up to date (well it has been for the countries I’ve used it in; including for any planned engineering works); for me it was an essential part of my travel in Europe. This app is linked to the Hafas system, which countries like Germany, Austria & Switzerland use for their train planning online tool. Eurail has done what the individual countries haven’t though and made it available offline.
