TS Class 4 was a series of five trams built by Strømmens Værksted for Trondheim Sporvei.

They were the first trams to have the wider 2.6 m (8 ft 6 in) bodies, that allowed four-abreast seating.

They remained in service until the Dalsenget fire on 10 October 1956, in which four of the trams burnt down.

36 was rebuilt by Strømmen with one cab and doors in one side only, and was assigned no.

In 1975, it was rebuilt as a maintenance car and salt tram, and was assigned no.
