The Eastern Østfold Line (Norwegian: Østfoldbanens østlige linje) is a 79-kilometer (49 mi) railway line which runs between Ski and Sarpsborg. It follows a more eastern route than the Østfold Line, with which it adjoins at both Ski Station and Sarpsborg Station, serving the Indre Østfold district. The line is single track and electrified. The Eastern Line serves the hourly L22 lines of the Oslo Commuter Rail, operated by the Norwegian State Railways. There is no regular traffic south of Rakkestad Station, although the line can be used for freight trains when the Western Line is closed.
The line was built at the same time as the Østfold Line, but opened three years later, on 24 November 1882. Stations were designed by Balthazar Lange. The Eastern Line has always featured fewer trains and had a lower standard. The line was electrified in 1958. It became the first line in Norway to feature the European Rail Traffic Management System, becoming operational in 2015.
The Eastern Østfold Line runs from Ski Station through the municipalities of Ski, Tomter, Hobøl, Eidsberg, Mysen, Rakkestad and Sarpsborg. It largely runs eastwards from Ski, then turns southward at Mysen. With a length of 78.9 kilometers (49.0 mi) it provides an alternative route to the Østfold Line between Ski and Sarpsborg. The line is single track and electrified at 15 kV 16 2⁄3 Hz AC. It is the only railway in Norway to feature ERTMS, with both GSM-R and European Train Control System (ETCS) Level 2. The line's peak elevation of 153 meters (502 ft) is reached at Eidsberg Station.
