The Gråkallbanen line operates as part of the public transportation system, since 1924 on 8.8km narrow gauge tracks from the city centre to Lian, in the outskirt of Trondheim. It is the northernmost tramline in the world. On a daily basis the tram runs approximately every 15min and needs about 40min to get to the final destination stopping at 21 stations. It is possible to book the veteran tram with carriages from the 50ies and experience the drive in 25min without stopping in between.
