Østhorn (station)

Nordberg was formerly the next northbound station, but it was closed in 1992, when the Sognsvann Line was upgraded to metro standard (power supply via third rail).

[4] In 1993, the stations on the Sognsvann Line were upgraded to metro standard, which involved a heightening and lengthening of the platforms, and installation of third rail power supply and a new signaling system.

[5] Many local residents opposed the new station upgrades, arguing that Nordberg had served the area well with its close connection to the elderly center Nordberghjemmet.

The rapid transit serves the station every 15 minutes, except in the late evening and on weekend mornings, when there is a 30-minute headway.

[16][17] The station is located at the bottom of a small hill named Havnabakken, where local residents toboggan at winter's time.
