History
The Oran-Relizane section was opened to travelers on November 1, 1868 and was extended to Khemis Miliana (called Affreville whilst part of French Algeria) on September 1, 1870. The Algiers-Blida section was extended to Boumedfaa on July 8, 1869, while the last segment - 29 kilometers from Affreville to Boumedfaa was completed on May 1, 1871 and enabled through-service from Algiers to Oran.[1]
More recently, the segment of the line from Algiers to El Affroun has been electrified to improve commuter rail connecting the two cities.
Line description
Algiers - El Affroun section
The 70-kilometer section from Algiers to El Affroun includes one of the five commuter rail services in the Algiers metropolitan area and is double-track and is electrified (25,000 volt).[2]
This section is the busiest in the entirety of SNTF network, with 130 passenger trains a day using the 10-kilometer Algiers-El Harrach section until the El Harrach wye. Of the 130 passenger trains using the Algiers-El Harrach section, 58 continue west and use the remainder of the Algiers-El Affroun section.
El Affroun - Oran section
The El Affroun-Oran segment is not electrified and is being upgraded from single-track to double-track. In 2015, 77 kilometers between Khemis Miliana and Chlef and 107 kilometers between Yellel and Oran have been double-tracked. Bypasses are being constructed to avoid Khemis Miliana and Relizane traffic for through-trains.[3]
Line description
The line is flat except for the 50 kilometers between El Affroun and Khemis Miliana where the elevation changes from 100 to 500-250 meters above sea level. A 7 kilometer tunnel is being built to more directly connect the Khemis Miliana and Oued Djer portion of this segment.[3]
Speeds on the line
Average speeds for passenger services on the line are 80–90 km/h. Since 2008, SNTF acquired DMUs capable of reaching 160 km/h which are expected to reach their top speed on flat double-track segments of the Algiers-Oran line.
