PCC streetcar
An invitation for tenders was issued in 1947. Ateliers de Constructions Electriques de Charleroi offered to build a European adoption of the PCC streetcar, although the necessary licenses for Scandinavia were held by Svenska Järnvägsverkstäderna. The trams met all of Oslo Sporveier's demands, except their high power usage. However, the downside was the high price and that foreign production would require currency exchange licenses, which could be complicated because part of the price was for royalties.
