It was operated with Class 92 diesel multiple units by Vy (formerly Norwegian State Railways, NSB), until 7 June 2020, when SJ Norge took over the contract until 2030.

It also serves as coach and bus station and the terminus of the intercity trains along the Dovre and Nordland Line.

[6][7] After entering Levanger Municipality, the line serves the villages of Åsen, Ronglan (limited services only) and Skogn.

[7][9][10] The Røros service continues south, making two more stops within Trondheim: Selsbakk and Heimdal.

The single daily service to Oppdal runs southwards, with an intermediate stop at Berkåk.

[7][11] Mittnabotåget start at Heimdal and operate northwards via Trondheim S to Hell, where they branch off and follow the Meråker Line.

These mostly run regional services, to Mo i Rana / Bodø and Røros / Hamar and not much on the commuter rail.

[21] Several of the station and operation buildings along the line have been preserved by the Norwegian Directorate for Cultural Heritage.

[15] The rearrangement of the train services in Trøndelag was made in 1993, when NSB announced the brand Trønderbanen.

The concept was based on the Jæren Commuter Rail which had been established the previous year, operating between Stavanger and Egersund.

The Trøndelag Commuter Rail would operate several services, north of Trondheim to Steinkjer and south to Oppdal and Tynset.

The initial plans called to the continued use of the Class 92 rolling stock, but saw change in schedules and new upgraded platforms for 15 million kr.

[25] This involved building a small platform house with a roof and glass walls, but a framework of wood, at each station.

The changes to the schedule involved almost a doubling of the number of departures, particularly between Trondheim and Stjørdal, where a one-hour headway was introduced.

[31] In 1997, NSB stated that the Trøndelag Commuter Rail was unprofitable and threatened to terminate it, along with an array of other services, if funding was not increased.

[33] The 20% increase that year was in part due to the FIS Nordic World Ski Championships 1997 being held in Trondheim, and was the service in the country with the largest growth.

[42] This also allowed NSB to operate some of services with double unit (four-car) trains in rush-hour.

The National Rail Administration stated that if any private companies wanted to operate the routes without subsidies, they were free to do so.

[47] As compensation, travelers between Trondheim and Rennebu Municipality and Oppdal with month passes were allowed to not pay for seat reservations on the intercity services.

[49] From June 2001, NSB introduced additional rush-hour trains between Trondheim and Steinkjer, giving a half-hour headway.

[50] From 22 September 2002, NSB and the Public Transportation Authority in Jämtlands County started a cooperation that involved two daily round trips with a Class 92 trains between Trondheim and Östersund in Sweden.

The brand Trønderbanen was abandoned and the administration was assimilated into the functional departments and partially moved to Oslo.

[55] The 4.4-kilometer (2.7 mi) long Gevingåsen Tunnel opened on 15 August 2011,[56] shortening travel time between Hommelvik and Værnes by five minutes.

[59] Norske Tog purchased new rolling stock from Stadler to service the line from 2021 together with the class 93s.
