NSB launched the Trøndelag Commuter Rail on 1 September 1993, of which the main service ran from Steinkjer to Trondheim. The initial plans called to the continued use of the Class 92 rolling stock, but saw change in schedules and the upgrading platforms for NOK 15 million. 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 and a station serving 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.
