 The tide changed in 1969 when the turning loop at Sinsen was needed to build the Sinsen Interchange—instead of closing the line a new loop was built at Muselunden.In 1972 the planned closing of the Ekeberg Line was canceled and remained, despite a new line needing to be built to allow passage during the construction of the central station.In 1977 the city council changed their decision to close down the tramway, mostly due to the 1973 oil crisis.
