Loenga–Alnabru Line
The Loenga–Alnabru Line (Norwegian: Loenga–Alnabrulinjen) is a 7.3-kilometer (4.5 mi) freight-only railway line in Oslo, Norway. It runs from the classification yard at Loenga(Norway) to Alnabru Freight Terminal, typically serving twenty trains per day. It allows trains to pass from the Østfold Line to Alnabru without passing via Oslo Central Station. It is also used by freight trains from the Sørlandet Line, which run via the Oslo Tunnel and cross over at Bryn Station. It is notorious for the steep hill Brynsbakken which it has to climb, giving it a gradient of 2.6 percent.

The line was opened from Bryn to Alnabru Station in 1904, with completion to Loenga on 1 May 1907. The line was electrified in 1928. A new classification yard opened at Alnabru in 1970. The line was the site of the Sjursøya Accident in 2010. In order to bypass Brynsbakken, the Norwegian National Rail Administration has proposed building a tunnel from further south on the Østfold Line, named the Bryn Diagonal.
