Situated 3.89 kilometers (2.42 mi) from Oslo Central Station, it features two platforms.

When the Trunk Line opened as the first railway in Norway on 1 September 1854, Bryn was merely a halt used to test brakes for west-bound trains towards Christiania.

Bryn received a ticket office the following year and in about 1860 it was fully classified as a station.

[2] Bryn Station received centralized traffic control from 24 January 1972, allowing it to be unmanned from 1 July 1975.

[1] The station is located at the top of a hill, Brynsbakken, which represents a steep climb for all west-bound freight trains.

[12] The Norwegian State Railways serves Grorud with line L1 of the Oslo Commuter Rail.

[15] Brynseng Station of the Oslo Metro is situated within five minutes' walk of Bryn.

An upgrade of the station has been called for, in which the tracks would be moved closer to the river and an island platform established.

Establishing a new hub at Bryn would not only involve several new lines terminating there, but would also require a significant urban renewal of the area.

[16] Oslo Bus Terminal has reached its capacity and Ruter wants to decentralize this function.

Due to the vicinity to Ring 3 and E6, Bryn has been identified as a suitable location for a south-easterly bus terminal.

It has been built in such a way that it can easily be rebuilt to feature an underground railway station, situated 43 meters (141 ft) below street level.

Ruter is also working with plans to rebuild Ring 2 as a tramway and build a tram line from Carl Berners plass.
