Farum station is the northern terminus of the Hareskov Line of Copenhagen's S-train network, a hybrid commuter rail and rapid transit system serving Greater Copenhagen.

It is served regularly by trains on the B-line which have a journey time to central Copenhagen of around 30 minutes.

[7] The station was remodeled completely prior to the line's conversion to S-trains in 1977.

[2] Farum station's first station building from 1906 was designed by the Danish architect Heinrich Wenck, known for the numerous railway stations he designed across Denmark in his capacity of head architect of the Danish State Railways from 1894 to 1921.

[2] Farum Station has been used as a location in the films Sikken en nat (1947), Fra den gamle købmandsgaard (1951) and Soldaterkammerater (1958).
