On 1 September 1993, NSB launched the Trøndelag Commuter Rail, of which the main service ran from Steinkjer to Trondheim. The initial plans called for the continued use of the Class 92 rolling stock, but saw change in schedules and the upgrading platforms for NOK 15 million. At the same time, the stations of Alstad, Langstein and Fleskhus were closed. The service from Trondheim to Steinkjer had ten daily round trips. After six months operation, the service had experienced a 40 percent growth in patronage. This was further increased with the opening of Trondheim Airport Station on 15 November 1994, which cost NOK 24 million. The upgrades to the airport also included a new taxiway, which resulted in second Værnes Tunnel being built. A station was also established to serve Levanger Hospital on 20 December 1995. On 10 November 1994, the line received automatic train control. NSB was split up on 1 December 1996 and the ownership of the tracks and infrastructure was inherited by the Norwegian National Rail Administration, while the operation of trains was taken over by the new NSB. From 1994, Di 6 and Di 8 locomotives were introduced, but the Di 6 proved unreliable and returned to the manufacturer.
