On 10 October 1956, almost all operative trams used by the company were lost to the flames. Subsequently, Trondheim Sporvei ordered the Class 6 from Strømmen. Five engines were salvaged from the fire, and were reused in trams 1 through 5. The remaining deliveries were numbered 10–32. The trams delivered with new motors, had four NEBB motors with a power output of 43 kW (58 hp). The Class 6 remained in service until 1984, when the Class 8 was delivered. Until then, the Class 7 served as the only tram on the Trondheim Tramway. Four trams and one trailer have been preserved by the Trondheim Tramway Museum.
