A proposal to replace the tramway with trolleybus was discarded by the city council. The depot was rebuilt, and 28 new Class 7 trams were ordered, in addition to 15 trailers from Strømmens Værksted and Hønefoss Karosserifabrikk, respectively. The bogies and motors were salvaged, and reused on the new
