The Randers–Aalborg railway line (Danish: Randers–Aalborg jernbane) is a 80.7 km (50.1 mi)[3] long standard gauge double track railway line in Jutland, Denmark which runs through the historical region of Himmerland between the cities of Randers and Aalborg.

[5] The line is owned and maintained by Rail Net Denmark and served with passenger trains operated by the Danish State Railways (DSB).

[1] The British civil engineering consortium Peto, Brassey and Betts was granted concession to build the Randers–Aalborg line on 18 March 1861.

[2] Work on the railway line started in October 1865, and was completed in the late summer of 1869.

During World War I traffic on the line became busy enough to be beyond the capacity of a single track.
