Alnabru–Grefsen · 1900 to today
The fragment of a ring that became a freight railway
Alnabanen was built to solve an immediate problem for a railway that had not yet reached central Oslo. The temporary solution found a permanent purpose.
Nordbanen needed a way into Christiania
When the first section of the northern railway opened in December 1900, its own approach from Grefsen into the city was not ready. The new track from Grefsen to Alnabru allowed rolling stock to reach Hovedbanen and the eastern station. Trains used it before Christmas, while regular operation began on 20 January 1901. 02
That role lasted less than two years. Gjøvikbanen received its direct approach in November 1902, and ordinary passenger trains no longer needed the detour through Alnabru. 02
The planned railway ring stopped at Alnabru
The connection belonged to a larger proposal for a northern railway ring. Plans envisaged tracks from Grefsen through Nydalen, Sagene and Majorstuen towards Bestum, where they would meet the western railway. 02 04
The full ring was never built. Only the eastern section between Grefsen and Alnabru was completed.
The opening to Bergen gave the line a lasting role
Alnabru grew as a freight area from 1907. When the complete railway to Bergen opened in 1909, Alnabanen became the natural link between its eastern approach through Gjøvikbanen and Oslo's freight yards. 02
Freight could move between Alnabru and Roa without entering the central passenger station. That relationship still defines the railway: a short urban connection serving trains whose journeys may cross half the country. 01 03
Factories connected directly to the railway
Factories established themselves along the corridor through Sinsen, Hasle, Økern and Ulven. At its busiest, the railway served around twenty to twenty-five industrial sidings, connecting warehouses and manufacturing sites directly to the network. 02
Road transport gradually took over local goods traffic. The last industrial sidings closed in 2008–2009, but the main railway remained because its national freight function was stronger than the local traffic that had once surrounded it. 02
Containers reshaped the eastern end
The railway landscape around Alnabru changed as the older yard developed into a modern terminal and Hovedbanen was realigned in 1971. Container and intermodal traffic replaced much of the wagon-by-wagon freight handling of the earlier yard. 02 03
Alnabru is now Norway's central rail-freight terminal. Alnabanen is one of the connections that lets those trains enter and leave the terminal without passing through Oslo S. 01 03
The temporary link remains a freight railway
Regular passenger trains do not use Alnabanen. Freight trains between Alnabru and Gjøvikbanen remain its everyday traffic, including trains heading towards Roa and onward to Western Norway. 01 02
Occasional heritage excursions also use the line. Its regular role is to move freight across Oslo without passing through Oslo S. 02
The railway in time
From temporary link to freight railway
A northern ring is imagined
Plans propose a railway arc from Grefsen through northern and western Oslo towards Bestum.
The first rolling stock passes
The new connection is used to move trains for Nordbanen before regular traffic begins.
Alnabanen opens
Regular operation starts between Grefsen and Alnabru.
Gjøvikbanen gains its own approach
The temporary passenger role fades when the direct route into Christiania opens.
Alnabru becomes a freight centre
The expanding yard and Oslo's new freight connections give the short railway a lasting purpose.
Bergen freight arrives
The completed railway to Bergen makes Alnabanen part of the east–west freight route through Roa.
The railway landscape changes
Hovedbanen is realigned and Alnabru develops around modern terminal traffic.
The last industrial sidings close
The local factory traffic disappears after more than a century of change along the line.
A freight railway through the city
Alnabanen continues to link Alnabru with Gjøvikbanen at Grefsen.
