TT Class 8 are the only remaining trams used on the Trondheim Tramway. Built by Linke-Hofmann-Busch (LHB) in 1984–85, they replaced the aging Class 7 trams used by Trondheim Trafikkselskap (TT). Of the eleven built, nine remain in service on the Gråkallen Line operated by Boreal Bane.

The Trondheim Tramway in Trondheim, Norway, is the world's most northerly tramway system, following the closure and dismantling of the Arkhangelsk tramways in Russia. It consists of one 8.8-km-long line, the Gråkallen Line, running from St. Olav's Gate in the city centre through Byåsen to Lian Station in Bymarka.
