The line was built in the least expensive way as a so-called tertiary railway with a 750 mm (2 ft 5+1⁄2 in) gauge track.

This stretch had no buildings or side tracks, and all facilities which meet the present-day visitor was built after becoming a heritage railway.

When the heritage railway was established the terminus was just outside the town center of Sørumsand, with the track leading to the station building already having been removed.

After another two years the entire operation, including station building, was finished, and the extended track was officially inaugurated.

The Urskog–Høland Line is now a museum under the umbrella of Museene i Akershus (MiA) run i cooperation with "Venneforeningen Tertitten".
