Loenga–Alnabru · 1907 to today
The freight route around Oslo S
The line gives freight trains a direct route between Alnabru, Loenga, Østfoldbanen and the port without passing through the passenger platforms at Oslo S.
The route joined yards, port and main lines
Loenga lies immediately southeast of central Oslo, beside the approach to Østfoldbanen and the railway towards the port. Alnabru developed farther up Groruddalen as the city's principal freight area. The line through Bryn connected them without sending goods trains through the passenger platforms at Oslo Ø. 02 03
That separation remains the railway's basic purpose. A train can move between the southern and eastern approaches to Oslo and the freight terminal at Alnabru while avoiding Oslo S. 02
Oslo's freight network expanded before its passenger network joined
The connection between Loenga and Alnabru opened in 1907, the same year Alnabru began to take shape as a freight yard. It was part of a larger effort to organise growing goods traffic around the capital. 03
At that time, the eastern and western passenger railways still ended on opposite sides of the city. Freight had gained practical cross-city connections decades before passengers received Oslotunnelen. 03
Brynsbakken turns a short route into a demanding one
From Loenga the railway climbs through Brynsbakken towards Bryn and Alnabru. The geography compresses freight movements, passenger tracks and junctions into a small part of east Oslo. 05
Trains crossing each other's paths can create queues for both freight and passenger traffic. That makes the connection a national capacity question, not merely a local siding between two yards. 05
Sjursøya keeps the southern end working
Loenga connects onward towards the port and Sjursøya. Freight from the harbour can reach the national network through Alnabru, while dedicated trains carry aviation fuel from the port towards Oslo Airport. 02
The traffic is specialised, but the route is flexible: it links the Østfold corridor, harbour facilities and the largest rail-freight terminal in Norway. 02 04
The modern terminal made the line more important
As freight handling moved towards containers and intermodal transport, Alnabru became the centre of the Norwegian system. Most rail-borne intermodal goods in the country pass through the terminal. 04
Godstogsporet Loenga–Alnabru is one of the routes into that system, used by trains continuing far beyond Oslo.
Sixteen wagons ran uncontrolled to Sydhavna
On 24 March 2010, sixteen empty freight wagons began rolling uncontrolled from Alnabru towards Loenga and Sydhavna. They reached the port area, where three people were killed and four were seriously injured. 06 07
The official investigation found that a misunderstanding led to the mechanical brake being released after the shunting engine had been uncoupled. It also found no barrier on the railway between Alnabru and Loenga or Sydhavna that could stop the wagons in a controlled way. The report issued seven safety recommendations. 06
The freight route in time
From 1907 to today
The freight connection opens
A railway between Loenga and Alnabru creates a direct goods route around the central passenger station.
Loenga becomes a freight yard
The yard south of the city centre handles trains for the port and the eastern network.
Alnabru becomes the national hub
Modern terminal traffic concentrates at Alnabru and strengthens the route's national role.
Runaway wagons reach Sjursøya
Sixteen empty freight wagons roll uncontrolled from Alnabru; three people are killed and four seriously injured.
The investigation report is published
The Accident Investigation Board sets out the causes and seven safety recommendations arising from the accident.
Port, fuel and through freight
The railway continues to connect Alnabru with Loenga, Sjursøya and the Østfold corridor.
