The two-car trains were delivered in 1984 and 1985, and were put into service on the Røros Line and southern part of the Nordland Line—which later became the Trøndelag Commuter Rail.

[1] From June 1986, the class was also put into the morning train from Mo i Rana to Trondheim and the return trip in the evening.

The service allowed passengers taking the morning train from Oslo to arrive in Mo i Rana in the evening.

[4] In 1993, NSB announced that the traffic around Trondheim would become the Trøndelag Commuter Rail, which would take over most of the Class 92 trains.

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.

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

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

Branded as Mittnabotåget, the trains were manned by NSB on the Norwegian side of the border, and by BK Tåg staff on the Swedish side, after the latter had won a public service obligation contract with the Swedish authority.

[12] During May and June 2012 all NSB Class 92 trains based in Trondheim were fitted with free wireless Internet access for the passengers.

The units were built by Duewag in 1984 and 1985 and consist of two cars, giving a seating capacity of 168 people.
