Each of the four Siemens motors had an effect of 50 kW (67 hp). There were two compartments, both with four-abreast seating, with reversible seats. Despite running in part in city streets, the trams were 2.6 m (8.5 ft) wide.[1]

The trams were taken out of service in 1968 and 1969. Two of the trams and both the trailers were scrapped the same year. No. 4 was kept as a working car until it was scrapped in 1985. No. 3 is preserved as a heritage tram at Trondheim Tramway Museum.[2]
