After the Dalsenget fire on 10 October 1956, where all the newest trams burnt down, the Singsaker Line was again served by the oldest trams with wooden benches. This lasted until the delivery of the Class 7 trams in 1957, which were also put into service on the Singsaker Line. For the first time the line was using the newest stock the company had. In 1958, after the opening of the Lade Line, Line 2's terminus was moved from the railway station to Lade, and Line 3 became the only line to serve the railway station.
