History
The original plans for the metro called for four smaller depots and a central workshop for both the trams and the metro at Etterstad, near Helsfyr Station. Following the 1960 decision to close the Oslo Tramway, it was decided that a common depot for the metro would be best, and an area at Ryen was purchased. The depot was taken into use at the same time as the Lambertseter was converted to and became the first line of the metro. From 1971, the area at Etterstad was taken into use as an operations central for both the city tramway, the Lilleaker Line, the Ekeberg Line and the metro. During the 1980s, some of the trains were stored at the end tunnels of the Furuset Line and the Grorud Line.
