Ryen Depot

The depot contains 19,000 square meters (200,000 sq ft) of buildings and has space for 120 trains, and consists of a workshop, inspection hall and a storage hall.

The inspection hall is used for smaller repairs and preemptive work, while the main workshop is used for larger repairs, such as mechanical and electric work on the bodies, bogies and motors.

[1] 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.
