The Trøndelag Commuter Rail (Norwegian: Trønderbanen, Urban East Norwegian: [ˈtrœ̀ndərˌbɑːnn̩]) is a commuter train service operating in Trøndelag county, Norway. It was operated by Vy (formerly Norwegian State Railways (NSB)) with Class 92 diesel multiple units, until 7 June 2020 when SJ Norge took over the contract until 2030. The service provides a commuter service connecting Trondheim to its suburbs, between towns in Innherred and as an airport rail link for Trondheim Airport, Værnes. Although passenger services have operated along the lines since 1864, the commuter train was created with an increase of service with existing rolling stock in 1993. In 2019, the system was used by 1.4 million passengers.
