The railway line is standard gauge and single track, and the distance from Hillerød to Helsingør is 20.8 kilometres (12.9 mi). The railway opened in 1864 as part of the North Line between Copenhagen and Helsingør by way of Hillerød. The line now constitutes the northernmost section of the original North Line which has not been electrified to form part of Copenhagen's commuter rail network, the S-train.

The North Line opened in 1864 between Copenhagen and Elsinore by way of Hillerød. It was originally the main line to Elsinore before the more direct Coast Line opened in 1897. The North Line was gradually electrified to form part of Copenhagen's commuter rail network, the S-train, with electrification reaching Hillerød station in 1968. The Little North Line now constitutes the northernmost section of the original North Line which has not been converted into S-train.[2]
