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.Bjerke & Holom: 54 The station was named for the farm Bryn, which means "natural meadow". It was not classified as a station, but it was therefore possible to board and disembark in that direction. From 2 June 1856 trains in both direction stopped at Bryn. In the third year of operations the railway built a spur from the halt. Bryn received a ticket office the following year and in about 1860 it was fully classified as a station.Norwegian Trunk Railway: 107
