How to move around Trondheim without a car.
The three letters you need to know to move about Trondheim are A, T and B. Established in 2009, AtB, which literally means “A to B”, oversees public transport in Trondheim, from issuing tenders for operators, to setting fares and promoting the services.
The bus system in Trondheim is extensive and reliable – most of the time. A useful map of the main routes is available here. Local commuter trains are popular, particularly from the southern suburb of Heimdal.
There used to be an extensive tramway system in Trondheim, but just one line remains in operation today. It runs from the city centre to Lian, via Byåsen along the western side of the river. It's a useful commuter service for those living on Byåsen, but also provides a handy way for people to reach the popular recreational area of Bymarka. All bus tickets and passes are valid for the tram.
For the best value fares, consider buying a travel pass to save money on the pricey single fares. A 24hr pass costs 105kr, a 72hr pass costs 165kr, a 7-day pass costs 235kr, and a 30-day pass costs 760kr. This compares to 50kr for a single ticket if you pay on the bus, or 41kr if you pay in advance at a machine.
Whether you are buying a pass or just paying single fares, the most convenient way to travel is by making digital payments via the AtB mobile app. Not only is it convenient, it provides a hefty discount on the single fare, which is just 32.80kr when using the app. In addition to the ticketing app, AtB also offer a timetable app that helps you plan journeys and check the live times from a specific stop.
