 A new line to Rodeløkka was opened on 3 January 1955 . The bus operation had been more expensive than the tram , and a double track line was built from Carl Berners plass through Dælenenggata to Rodeløkka . The balloon loop was built around the block of Dælenengata , Fagerheimgata , Marstrandgata and Københavngata . The line was connected to the old Rodeløkka Line with a triangular loop in Københavngata . On 23 April 1961 , all traffic on the Rodeløkka Line was terminated . The tracks were removed between 1962 and 1964 .
