The Boughezoul–Laghouat Line is one of the lines in the Algerian railway network. It was inaugurated in and connects Boughezoul (in the Médéa province) to Laghouat (in the Laghouat province).

Stretching for 250 km, the line is part of the Algerian railway lines known as "penetrating lines." These are a group of three north–south oriented lines that link the stations of the northern artery of Algeria (the lines from Oran to Annaba via Algiers and Constantine) to cities in the northern Algerian Sahara. The Boughezoul-Laghouat line is referred to as the "Central Penetrating Line," with the other two being the Oued Tlelat–Béchar line and the El Guerrah–Touggourt line, known as the "Western Penetrating Line" and "Eastern Penetrating Line," respectively.

History

The initial project for the construction of a railway line connecting Boughezoul to Laghouat was launched in 2005 by the National Agency for studies and follow up the accomplishment of Railway Investments (ANESRIF). This project was part of a significant railway investment program initiated by the Algerian government, aimed at modernizing existing infrastructure and creating new lines, with a budget of 24.8 billion dollars.[1]

Among the new lines, the construction of three of them (Tissemsilt-Boughezoul, Saida-Tiaret, and Relizane-Tiaret-Tissemsilt) was awarded in 2009 to two Chinese construction groups: China Railway Group (CRG) and China Civil Engineering Construction Corporation (CCECC), for a total amount of 2.5 billion dollars. However, delays in the construction of these three lines, unsuccessful bidding processes due to a lack of competitors or non-compliant bids for other lines, as well as suspicions of corruption in contract awards, led ANESRIF to cancel the contracts and projects associated with the 2005 plan in 2011.[2] [3]

In 2012, ANESRIF revived the projects from 2005. This new plan, comprising thirteen railway projects, included the construction of 643 km of new lines, including the Boughezoul-Laghouat line, as well as the modernization of 225 km of existing lines[4] [5] [6]

Originally scheduled for completion and inauguration in the first quarter of 2023,[7] [8] the line was finally inaugurated on, by Algerian President Abdelmadjid Tebboune. The inauguration took place at the new Djelfa station, and the line was put into service on the same day.[9] [10] The first commercial passenger service commenced from the Laghouat station on .[11]

The Line

Line Characteristics

The Boughezoul–Laghouat line spans a distance of 250 km[12] and consists of a single Standard-gauge railway that is not electrified.[13]

Similar to other new or renovated lines in Algeria, the Boughezoul–Laghouat line is equipped with the ERTMS/ETCS railway signaling systems and the GSM-R communication system. These signaling and communication systems were implemented by ESTEL RA, a joint venture between SNTF (Algerian National Rail Transport Company) and Siemens.[14]

The contract between ANESRIF and ESTEL includes the provision of the following equipment for the line: the ETCS Trainguard 100 ETCS Level 1 system, the Vicos automatic operation control system, the Simis W electronic interlocking system for the six stations along the line, as well as the RailCom communication management system.[15] [16]

Route and profile

The line traverses two major geographic regions in northern Algeria from north to south:

In its passage through the Hauts Plateaux, the line follows a relatively straight alignment without encountering major obstacles to overcome or cross. The second part of the route is more winding as it navigates around the pre-Saharan Atlas mountains (djebels).

The line consists of two sections:[17] [18] [19]

Profile

The line originates from Boughezoul Station (PK 0 of the line), situated at an altitude of 652 m in the northern part of the central High Plateaus region. Leaving the station, the line briefly shares its route with the Tissemsilt-M'Sila line for approximately 3 km before taking a north-south orientation that continues until Laghouat.

About 17 km south of Boughezoul, the line reaches its lowest point, with an altitude of 632 m, at the Dayet el Kerfa depression. As it traverses the southern High Plateaus, the line maintains a consistent slope across the Aïn Oussara plain until it reaches the foothills of the Saharan Atlas. To bypass the El Khaitsar mountain, located near the town of Guelt Es Stel, the line takes a western route, reaching an altitude of 975 m.

Beyond El Khaitsar, the line enters the Chotts Zahrez Gharbi and Zahrez Chergui depressions, where its altitude decreases to 935 m south of Hassi Bahbah. It then transitions from the High Plateaus to ascending the Ouled Naïl mountains in the central Saharan Atlas. Passing through the Sahari mountain range along the course of the El Melha wadi, the line tunnels through the northeastern edge of the Senalba mountain range before reaching Djelfa. Skirting Djelfa to the east, the line arrives at its new station southeast of the city, situated at an altitude of 1,195 m.

At PK 156, approximately 12 km southwest of Djelfa, the line reaches its highest point, peaking at 1,274 m while crossing the northeastern tip of the Djellal Chergui mountain near the Caravanes Pass (a road pass on National Highway 1). Descending from the Saharan Atlas, the line follows a lengthy valley for about 90 km, bordered to the northwest by the Djellal Chergui and Milok mountains, and to the southeast by the Zerga, Dahouane, and Dakhla mountains. Exiting this valley, the line leaves the Saharan Atlas behind and enters the northern Algerian Sahara, ultimately reaching Laghouat Station situated southwest of the city at an altitude of 785 m.

Speeds

The maximum speed of passenger trains is 220 km/h,[20] [21] while the speed of freight trains is 100 km/h.[22]

Railway service

In 2023, the line is served by six daily trains with a capacity of 380 passengers:[23]

The travel time from Boughezoul to Laghouat is approximately 2 hours and 40 minutes, while the travel time from Djelfa to Laghouat is approximately 45 minutes.[24] [25]

The trains operating the Boughezoul-Laghouat service are Alstom Coradia bi-mode electric and diesel multiple units (class SNTF ZZe).

Stations of the line

The line includes six passenger stations:[26]

and three freight stations. Djelfa station is a mixed passenger and freight station. The freight stations of Boughezoul and Laghouat are located at a distance from the passenger stations.[27] The storage capacity for goods at each of these three stations is 58,000 m2, with container storage space capable of accommodating 5,500 units.[28]

Extensions

The commissioning of the Boughezoul to Laghouat line is a step in the realization of the future "Trans-Saharan Central Penetrating Line," a 2,439 km line that will connect Algiers to cities in the Sahara region up to the Algerian-Nigerian border.[29] This link will pass through the provinces of Médéa, Djelfa, Laghouat, Ghardaïa, El Menia, In Salah, and Tamanrasset,[30] and will utilize the following lines:

Two railway branches will be added to the Central Penetrating Line:
