The original building, designed by Heinrich Ernst Schirmer and Wilhelm von Hanno, burned down in 1862.

Grorud was selected as one of nine original station which was built for Norway's first railway, the Trunk Line.

[1] Grorud was selected both because it was at about half-way between Christiania and Lillestrøm Station, but also because it had many large farms and sawmills in its vicinity.

Travel time was forty minutes to Christiania East Station and made transport to the capital easy.

Originally the only level crossing of the line between Grorud and Furuset was situated at the station.

[4] The following years the line between Christiania and Lillestrøm was upgraded to double track, which opened past Grorud on 1 October 1903.

[10] Grorud was the only station along the line which, due to the recent upgrades, was large enough that it did not need an expansion.

[8] Grorud became a more distinct area around the beginning of the 20th century, with a school and a church.

[5] Grorud Station received centralized traffic control on 24 January 1972, allowing it to be unmanned starting 2 June 1991.

[13] Vy serves Grorud with line L1 of the Oslo Commuter Rail.
