TS Class 7 was a series of 28 trams and 15 trailers built by Strømmens Værksted for Trondheim Sporvei.

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.

Four trams and one trailer have been preserved by the Trondheim Tramway Museum.
