Grønland is a rapid transit station on the Oslo Metro in the Common Tunnel serving all six lines.

The subway schedule recommends that passengers use Grønland as a transfer point between different lines because its platforms are less crowded than its neighbouring stations.

This was caused by cracks in the bedrock which allowed surface water to run down into the station, and was fixed by spraying a clogging chemical into the rocks.

[3] The station underwent a major renovation, starting on 1 February 1989, which included the entrance, passenger hallways and platform area.

[10] Grønland is within walking distance of Oslo Bus Terminal, which serves regional and intercity coaches.
