History of rail transport in Algeria

The history of rail transport in Algeria began in 1857 during the French colonization with the implementation of an initial plan for the creation of a 1,357 kilometres (843 mi) railway network. This plan, formalized by a decree from Emperor Napoleon III, defined the initial framework of the Algerian railway network, which continued to evolve throughout the second half of the 19th century, both in terms of its scale and structure.

The initial railway network revolved around a main railway artery connecting the capital cities of the three departments of the country: Algiers, Constantine, and Oran. Branching out from these main lines were secondary lines that extended towards the major ports of the colony. These early railway lines primarily served the transportation of agricultural products and raw materials from Algeria to mainland France, as well as the movement of manufactured goods from coastal cities to the interior regions of the colony.

The Algerian railway network was constructed in a fragmented manner across different regions due to the presence of multiple concessionary companies and the lack of overall coordination. It was not until the early 20th century that the French government and the Algerian government unified the various components of the network and simplified its management by reducing the number of companies involved.

The railway network underwent significant evolution throughout the first half of the 20th century. At its peak, just before the outbreak of the Second World War, it encompassed up to 5,000 kilometres (3,100 mi) of railway lines. However, following the war, railway transport in Algeria faced competition from road transport, and several secondary lines were closed in the decades leading up to the country's independence.

In 1962, the newly established Algerian state initially focused on managing the existing railway network, ensuring efficient operation and maintenance. It was not until the early 2000s that a major plan for modernization and expansion of the network was implemented. This involved the creation of new railway lines, the doubling or electrification of existing ones, and a gradual extension of the network to cover the entire country.

Significant developments included the construction of a railway ring road in the High Plateaus and the ongoing completion of feeder lines connecting major cities in the northern Sahara region. Moreover, studies are currently being conducted to extend these lines through the Sahara, connecting the Algerian railway network with neighbouring countries to the south. This expansion aims to facilitate the transportation of various goods, such as minerals and petrochemical products, by rail between Sahelian countries, Algerian ports, Europe, and other global destinations.

Period of Colonial Algeria

Emile Pereire, the first political figure to propose a railway project in Algeria in 1833.

Railway line projects in Algeria prior to the 1857 decree

Just a few years after the beginning of France's conquest of Algeria in 1830, politicians, industrialists, and investors proposed various railway line projects in Algeria.

In 1833 the financier and politician Émile Pereire published an article in the French newspaper Le National, in addition to discussing his ideas for the administration and colonization of Algeria, he presented a plan for establishing a railway system connecting Bône (Annaba) and Constantine to Algiers, and Algiers to Oran. According to Pereire:

With the leveling work carried out by the troops, free expropriation, and obtaining rails at half price from England, it would be sufficient for this 150-league line to incur a total expenditure of 20 to 25 million. This investment ... would allow for the establishment of an economically efficient system, effectively protecting the entire coast from Bedouin incursions. ... when 20 locomotive engines are used, they can transport an army of 18,000 infantry soldiers, 2,000 horse-mounted soldiers, and 45 cannons from Algiers to Oran or Constantine within 24 hours. This capability ensures that there will no longer be a need to worry about serious attacks.

— Émile Pereire, Le National

In 1844 engineer Édouard de Redon put forward a proposal to construct a railway from Algiers to Blida, following the foothills of the Atlas Mountains. At the same time, Frédéric and Eugène Lacroix presented their project for a railway line connecting Philippeville (Skikda) to Constantine, including a port at Stora. M. Garbes also suggested two railway lines in the Oran region: one from Oran to Mostaganem and Hillil (Yellel), and another from Oran to Tlemcen.

In 1854 a group of investors developed a project to establish a comprehensive railway network in Algeria. This plan included multiple lines, such as the Algiers-Oran, Algiers-Constantine, Constantine-Bône with a branch line to Philippeville, Tlemcen-Mascara via Sidi Bel Abbès, and various branch lines to Mostaganem, Ténès, and Bougie (Béjaïa).

While the need for a railway network to promote colonization in Algeria was recognized during the assessment of these projects, the preliminary studies were deemed inadequate as they were either limited to specific regions or driven by private interests focusing on transporting goods from productive areas or mines seeking concessions. To address these concerns and fully facilitate colonization, the governor of Algeria, Jacques Louis Randon, assigned General François de Chabaud-Latour to conduct thorough studies and develop a comprehensive plan for the railway network. It was the outcome of these studies that led to the issuance of the imperial decree in 1857, marking the first concrete plan to establish a railway network in Algeria.

First railway line

The Algiers–Blida line, which was inaugurated in 1862, is widely recognized as the first railway line in Algeria designed for both passenger and freight transportation. But the real first line was established in 1858 by the Société Civile des Mines et Hauts-Fourneaux des Karezas. This initial railway line spanned 11 km and connected the Karezas iron mine to the Seybouse River port, situated on the outskirts of Annaba. Operating on a meter-gauge track, it commenced operations on 1 September 1859, exclusively for the transportation of ore. Subsequently, it served as the foundation for the future Bône-Saint-Charles line.

First railway plan in Algeria: the 1857 program

Decree of 8 April 1857

François de Chabaud-Latour, who authored a report emphasizing the need for railway development in Algeria.

After the French conquest of Algeria in 1830, several suggestions were made to establish a railway network that would facilitate the colonization of the region. But no substantial projects were initiated in response to these proposals. It was not until the mid-1850s that General François de Chabaud-Latour, the senior commander of the engineering corps in Algeria, was assigned by Governor Jacques Louis Randon to assess the various suggestions and provide a comprehensive report. In one of his conclusions, he asserted:

To promote colonization, it is important to first develop good transportation routes that allow colonists to export their products to the coast. However, we should not encourage large-scale migration of farmers from the Motherland to Algeria until these infrastructure projects are completed.

— François de Chabaud-Latour

It was only in 1857 that Marshal Vaillant, the Minister of War at the time, presented Emperor Napoleon III with a comprehensive plan for the construction of Algerian railways. The main axes of this plan are as follows:

Sire,

You have deemed it necessary to provide Algeria with railways, to satisfy the existing agricultural interests and accelerate their progressive development. Railways should indeed be considered one of the most powerful factors for the future prosperity of our vast conquest. A railway network encompassing the three provinces will bring life and wealth through the convenient and swift transportation of agricultural and industrial products, as well as facilitate the movement of a growing population of colonists.

...

I have prepared a plan for a comprehensive network of Algerian railways. This network would consist of:

A main line running parallel to the sea, connecting the capitals of the three provinces and serving the major towns. In the east, it would span between Alger and Constantine, and in the west, between Alger and Oran, with a branch line to Tlemcen via Sidi-bel-Abbès.

Lines originating from the main ports and converging onto this main artery, thus connecting Bône and Philippeville to Constantine, Bougie to Sétif, Ténès to Orléansville, and Mostaganem and Arzew to Relizane."

— Jean-Baptiste Philibert Vaillant

Portrait of Marshal Vaillant, the initiator of the first railway network in Algeria.

The emperor, agreeing with the plan, signed a decree on 8 April 1857, to create a railway network in Algeria. This decree, known as the 1857 Classification Decree, outlined the key aspects of the railway program in Algeria. It proposed the construction of a 1,357 kilometres (843 mi) network, consisting of:

• A main line running parallel to the coast, connecting the capitals of the three provinces: Constantine, Algiers, and Oran. It would pass through or near Aumale (Sour El-Ghozlane), Sétif, Blida, Orléansville (Chlef), Saint-Denis-du-Sig (Sig), and Sainte-Barbe-du-Tlélat (Oued Tlélat), the total length of the line would be approximately 881 km.
• Additionally, there would be six branch lines starting from the main ports and joining the coastal line:
  • From Philippeville to Constantine (87 km);
  • From Bougie to Sétif (110 km);
  • From Bône to Constantine (202 km);
  • From Ténès to Orléansville (58 km);
  • From Arzew and Mostaganem to Relizane (68 km);
  • From Oran to Tlemcen via Sainte-Barbe-du-Tlélat and Sidi Bel Abbès (120 km);

The lines outlined in the 1857 plan

Concessions of the first lines to the Algerian Railway Company (CFA)

Ferdinand Barrot, President of the CFA Company.

The law of 20 June 1860 declares three sections of the lines planned in the 1857 plan as being of public utility:

• Algiers – Blida (51 km);
• Oran – Saint-Denis-du-Sig (52 km);
• Philippeville – Constantine (87 km);

Only 190 km of railway lines were constructed out of the original plan of 1,357 km.

These short lines were given priority for construction as they connected the three major cities of colonial Algeria: Algiers, Constantine, and Oran. The primary objectives were to facilitate the exploitation of natural resources in these regions and to solidify French presence in Algeria.

The concession for these three lines was granted to a joint-stock company Chemins de Fer Algériens (CFA) through an imperial decree on 11 July 1860. The CFA was specifically established by a group of businessmen, including the director of the Marseille port, who recognized the opportunity to enhance port activity by importing products from the colony.

However, the construction of the Algiers–Blida railway line was initiated in 1859, well before its concession was granted to the Algerian Railway Company (CFA).

Reattribution of concessions to the Paris, Lyons, Mediterranean Railway Company (PLM)

The Algerian Railway Company (CFA), which was granted the concession for three priority lines in 1860, faced immediate financial challenges. Insufficient subscribed shares (only 33 000 out of 100 000 shares offered) resulted in a lack of capital, leading the company to declare bankruptcy. As a result, in 1863, all concessions were transferred to Chemins de fer de Paris à Lyon et à la Méditerranée (PLM) through the enactment of the 11 June 1863 law.

This redistribution was a decision made by Eugène Rouher, who served as the Minister of Commerce and Public Works. It was a result of his support for the PLM company during a conflict with the company Chemins de fer du Midi over the allocation of the Sète–Marseille line. As the PLM company emerged victorious from the dispute, the minister imposed the transfer of concessions from the CFA to the PLM as a form of compensation. The PLM gladly accepted the minister's decision, seeing it as a favorable outcome. In fact, the PLM management informed its shareholders that they anticipated certain indirect benefits from the completion of the Algerian railway network. They noted that their metropolitan network, which serviced the region facing Algeria, would now handle all traffic travelling to and from Algeria, thereby increasing their overall rail traffic. They also emphasized their keen interest in the creation and expansion of railway lines in Algeria.

Consequently, the PLM company became the concessionaire for 543 km of railway lines in Algeria, including the entire Algiers–Oran line :

• The section from Algiers to Blida (51 km) of the Algiers–Oran line;
• The section from Blida to Saint-Denis-du-Sig (348 km) of the Algiers–Oran line;
• The section from Saint-Denis-du-Sig to Oran (59 km) of the Algiers–Oran line;
• The Philippeville to Constantine line (85 km);

By acquiring these concessions, the PLM, which already operated an extensive railway network in mainland France, now extended its reach from Marseille, the primary port for journeys to Algiers, all the way into Algeria.

Execution of the 1857 plan's lines

The French government launched the construction of the Algiers to Blida section, which is the primary segment of the Algiers–Oran line, without waiting for the declaration of public utility. The construction work commences on 12 December 1859. Initially, it is the French Army that takes on the task of building the railway line. The first section, connecting Algiers to Oran, is completed and opens for goods transportation on September 8, 1862, followed by passenger services on 25 October 1862.

The Algiers-Oran railway line was gradually opened in multiple stages:

• The Algiers to Blida section was inaugurated on 25 October 1862;
• The Oran to Relizane section was opened on 1 November 1868;
• The Blida to Boumedfaa section was completed on 8 July 1869;
• The Relizane to Affreville (now Khemis Miliana) section was put into service on 1 September 1870.
• Finally, the Affreville to Boumedfaa section was opened on 1 May 1871.

As a result the entire 420 km-long line was fully operational in 1871, marking the completion of the project 12 years after construction began;

Philippeville–Constantine line

Originally granted to the CFA company in 1860, the concession for the Philippeville–Constantine railway line was transferred to the PLM in 1863 following the former's bankruptcy. The construction of this line was undertaken by the new company.

The line was officially opened on 1 September 1870. With a length of 87 km, it was later connected to the Constantine to Alger line, which was fully operational in 1886, forming the present-day Algiers to Skikda line.

Other lines of the first plan

Not all of the other lines outlined in the initial plan were fully realized. Some underwent changes in their routes, while others were never built :

• Algiers–Constantine line: The declaration of public utility (DUP) for this line was issued on 15 December 1875. The first concession, covering the section from Constantine to Sétif, was granted on the same date. The remaining sections of the line were granted in separate concessions between 1877 and 1880. The entire line was finally opened in 1886.
• Bougie–Sétif line: This line was never constructed. Instead, a connection between Beni Mansour, on the Algiers to Constantine line, and Bougie (now Béjaïa) was preferred and put into operation in 1889.
• Bône–Constantine line: The original planned route for this line was not followed. Instead, a line connecting Bône (now Annaba) to Saint-Charles (now Ramdane Djamel), a town on the Philippeville–Constantine line, was preferred. This line, completed in 1904, currently forms the Ramdane Djamel to Annaba line.
• Ténès–Orléansville line (now Chlef): This line was not constructed as part of the initial plan.
• Arzew and Mostaganem to Relizane line: This line was not built according to the initial plan.
• Sainte-Barbe-du-Tlélat (now Oued Tlelat) to Tlemcen line, via Sidi Bel Abbès: This line was not constructed as part of the initial plan.

• Compilation of station views along the Algiers-Constantine line

Lines outside the 1857 plan

The governor's decree on 2 June 1863 allowed for the extension of the Karesas Mines railway line to the Seybouse port in Bône (now Annaba), both towards the north and west, reaching the area of Aïn Mokra (Berrahal).

Second railway plan in Algeria: the 1874 program

Decrees of 1874 authorizing the creation of local interest lines

The decree of 29 April 1874 approves the agreements reached between the Governor-General of Algeria and the Compagnie franco-algérienne (FA) for the concession of a railway line from Arzew to Saïda, with an extension of 70 km in the direction of Geryville (now El Bayadh). The concession is granted to the FA company without subsidy or interest guarantee, but with the exclusive privilege of exploiting the alfa on 300 000 hectares of land in the Hautes Plaines region; the line will transport alfa to the port of Arzew for importation to mainland France.

The decree of 7 May 1874 transposes the French law of 12 July 1865 on local interest railways to Algeria. Until that date, no departmental line had been conceded in Algeria.

The lines of the second plan

The decree of 7 May 1874, allowed for the granting of concessions to three additional railway companies :

• Société de construction des Batignolles (SCB), later known as Compagnie des chemins de fer Bône-Guelma (BG);
• Compagnie de l'Ouest algérien (COA);
• Compagnie de l'Est algérien (CEA).

Concessions granted by the 1874 program.

Third Railway Plan in Algeria: the 1879 Program

Law of July 18, 1879: New Lines of General Interest and Reclassification of Local Interest Lines

The law of 18 July 1879 defines a new comprehensive plan, known as the classification plan, which incorporates the provisions of the 1857 plan while adapting it to the lines created or conceded later as part of the 1874 program.

This new plan allows for the creation of 1,747 km (1,086 mi) of new lines, added to the 1,079 km (670 mi) of already built lines, forming a cohesive network.

Lines from the 1857, 1874, and 1879 plans.

Lines of the Third Plan

The 1879 plan envisions the construction of twenty new lines classified in the general network:

• from La Sénia, on the Oran to Sainte-Barbe-du-Tlelat line, to Tlemcen via Aïn Témouchent (145 km (90 mi));
• from Tlemcen to the Moroccan border (58 km (36 mi));
• from the mining massif of Rio-Salado to the La Sénia to Aïn Témouchent line (25 km (16 mi));
• from Sebdou to the Tlemcen to the Moroccan border line (45 km (28 mi));
• from Sidi Bel Abbès to Magenta (61 km (38 mi));
• from Mostaganem to Tiaret, via Aïn Tedles and Relizane (179 km (111 mi));
• from Mascara to Aïn Tizi (12 km (7.5 mi));
• from Ténès to Orléansville (58 km (36 mi));
• from Affreville to Haouch-Moghzen (48 km (30 mi));
• from Mouzaïaville to Berrouaghia via Haouch-Moghzen (96 km (60 mi));
• from Berrouaghia to the Trembles (70 km (43 mi));
• from the Trembles to Bourdj-Bouira (30 km (19 mi));
• from Ménerville to Tizi Ouzou (56 km (35 mi));
• from Beni Mansour to Bougie (97 km (60 mi));
• from Tixter to Bougie (85 km (53 mi));
• from El Guerrah to Batna (80 km (50 mi));
• from Batna to Biskra (115 km (71 mi));
• from Aïn Beida to Ouled Rahmoune, on the Constantine to Sétif line (80 km (50 mi));
• from Souk Ahras to Tébessa (126 km (78 mi));

and the incorporation into the general network of local lines already conceded in the 1874 program:

from Sainte-Barbe-du-Tlelat, on the Oran to Algiers line, to Sidi Bel Abbes (51 km (32 mi));

from Maison-Carrée to Ménerville, on the Algiers to Constantine line (43 km (27 mi));

from Ménerville to Sétif, on the Algiers to Constantine line (254 km (158 mi)).

Evolution of the network from 1880 to 1900

By 1880, the Algerian railway network already consists of 1,150 km (710 mi) of tracks. The laws implementing the 1879 plan triple its length.

Between 1880 and 1900 several laws are enacted to grant concessions to railway companies for the construction and operation of the lines in the 1879 plan. The table below lists these concessions.

• 
  Inauguration of the Oran–Tlemcen line in 1885 (the extension from Aïn Témouchent to Tlemcen was not realized; the Tabia–Tlemcen line was built instead).
•

Network at the end of the 19th century: A great disparity of lines

At the end of the 19th Century, five railway companies operated Algerian railway lines:

The railway viaduct of El Ourit, on the Tabia to Tlemcen line.

• Compagnie des chemins de fer de Paris à Lyon et à la Méditerranée (PLM), which operated the Algiers to Oran and the Philippeville to Constantine lines;
• Compagnie de l'Est algérien (CEA), which operated the Algiers to Constantine line, the lines east of Algiers towards Tizi Ouzou and Bougie, and those in the Constantine region towards Batna, Biskra, and Aïn Beida;
• Compagnie des chemins de fer Bône-Guelma (CBG), which operated lines in the Bône region towards Duvivier, Guelma, Kroubs, Souk Ahras, Tébessa, and Tunisia;
• Compagnie franco-algérienne (FA), which operated the lines from Mostaganem to Tiaret, from Arzew to Aïn Sefra, and from Aïn Tizi to Mascara;
• Compagnie de l'Ouest algérien (COA), which operated lines in the Oran region towards Sidi Bel Abbès, Ras El Ma, Aïn Témouchent, Tlemcen, and the Blida to Berrouaghia and Boghari line.

It is noteworthy that, for three of the five companies, several lines in their respective networks did not have connections with each other:

The Blida to Berrouaghia line, with a gauge of 1,055 mm, runs through the Chiffa Gorges.

• The two PLM lines: from Algiers to Oran and from Philippeville to Constantine, were separated by 462 km (287 mi).
• The three COA lines: from La Sénia to Aïn Témouchent, from Sainte-Barbe-du-Tlélat to Tlemcen and Ras El Ma, and from Blida to Berrouaghia, branch off the PLM's Algiers to Oran line without communicating with each other.
• The two FA lines: from Arzew to Aïn Sefra and from Mostaganem to Tiaret, only connected through the Relizane to Mohammadia

Evolution and consolidation of the network in the early 20th century

Toward railway autonomy for Algeria

1892 marks the beginning of a pause in the creation of general interest lines in Algeria for about a decade. Only a few small local interest lines are declared of public utility during this period:

• The Oran to Arzew line on 9 April 1898;
• The line from Aïn Beïda to Khenchela on 30 July 1900;
• The tramway from Saint-Paul to Randon on 11 May 1898;
• The lines of the Chemins de fer sur routes d'Algérie company: from El Affroun to Marengo; from the port of Algiers to Saint-Eugène and Rovigo; from Dellys to Boghni, from Algiers to Coléa on 16 January 1892;
• The Aïn Mokra to Saint-Charles line on 25 April 1900;
• The tramway from Bône to La Calle on 18 August 1900.

The French state disengages from direct governance of the construction and financing of the railway network in Algeria and aims to transfer this responsibility to its colony. The laws of 19 December 1900 and 23 July 1904 create a special budget to grant financial autonomy to Algeria, in terms of public works, with a separate budget for the management and development of its railway network. The Colony now has the opportunity to add new railway tracks to the insufficient network provided by the Metropolis. But first, some order must be brought to the operational network before addressing its development, including improving and unifying the tariff structure for passenger services and freight transport.

The governor-general encourages Algerian companies to unify the rates for mainline (GV) and low speed (PV). The Compagnie des chemins de fer Bône-Guelma, and Compagnie de l'Ouest algérien, and PLM undertake studies to achieve a unification of tariffs. Only the Compagnie de l'Est algérien refuses.

Acquisitions of companies and network reorganization

At the end of the 19th century and during the early years of the 20th century, especially during the First World War, Algerian railway companies faced financial difficulties. These difficulties led to the disappearance of four of them, and the Algerian government bought the lines of their networks, which were transferred either to the new Compagnie des chemins de fer algériens de l'État (CFAE), created on 27 September 1912, to operate the lines acquired by the Algerian government, or to the PLM company.

Acquisition of the Compagnie franco-algérienne

The Compagnie franco-algérienne, not very prosperous because its lines were not very profitable, faced financial difficulties, leading it to lease its network to the Compagnie de l'Ouest algérien for five years in 1888. It eventually filed for bankruptcy in 1890 but retained its concessions for a few more years. The decree of 21 December 1900 authorized the state to operate the lines of the Compagnie franco-algérienne. The network was bought on 28 December 1900, and placed under the supervision of the Administration métropolitaine des chemins de fer d'État. It was transferred to the Compagnie des chemins de fer algériens de l'État in 1912.

Acquisition of the Compagnie de l'Est algérien

After the Compagnie de l'Est algérien refused to unify its freight transport rates with those of other companies, citing potential operating losses, the governor-general and the Algerian assemblies decided to buy the company's concessions and operate its network directly. The decree of 25 August 1907 confirmed this purchase, which took effect on 12 May 1908. Like the network of the Compagnie franco-algérienne, the network of the Compagnie de l'Est algérien was definitively transferred to the CFAE in 1912.

Acquisition of the Compagnie des chemins de fer Bône-Guelma

The Compagnie des chemins de fer Bône-Guelma, which had agreed to unify its freight transport rates, wanted to renegotiate its agreements to better incorporate its costs for transporting mining products from southern Constantine. As the negotiations failed, the Algerian government considered buying the Algerian part of the Compagnie des chemins de fer Bône-Guelma's network (which also operated lines in Tunisia). This acquisition was authorized by the decree of 9 June 1914, and it was completed on 1 January 1915.

Acquisition of the Compagnie de l'Ouest algérien

World War I had repercussions on the Algerian railway network. From the beginning of the war, the railways came under the control of the French army. Requisitions and military priorities paralyzed the commercial railway transport of Algerian companies. The reduction in personnel and the exorbitant increase in the costs of raw materials, including coal, due to the war, further worsened the situation. These difficulties greatly deteriorated the financial situation of the companies, especially the Company of Western Algeria. Faced with increased expenses caused by the war and a decrease in profits, the company requested renegotiations of the financial clauses of its concessions. It declared its inability to continue operating its network beyond 31 December 1920. The Algerian authorities then decided to proceed with the repurchase of the company's network. This repurchase was formalized by the decree of 31 December 1920. The operation of the network was temporarily transferred to the PLM company on 1 July 1921, and then permanently in 1924.

Acquisition of the Paris–Lyon–Mediterranean Railway Company in Algeria

The previous acquisitions have led to improvements in the management and organization of the network but have not succeeded in homogenizing it. The lines of the PLM Company remained intertwined with those of the CFAE. Additionally, the PLM Company needed to revise its 1863 agreement with the State to account for the economic conditions in the aftermath of the war. A reform of the organization of Algeria's general interest railways became necessary.

A new agreement was established on 1 July 1921, between the governor-general of Algeria on one hand, and the administration of the Algerian State Railways and the PLM Company on the other. This agreement stipulates that:

– The Governor-General acquires from the Paris-Lyon-Mediterranean Company, starting from 1 January 1922, all the lines conceded to it by the Convention of 1 May 1863, namely: the line from Algiers to Oran and the line from Philippeville to Constantine. – The Governor-General, representing Algeria, leases to the PLM Company from 1 January 1922, the following lines: from Algiers to Oran, from La Sénia to Aïn-Témouchent, from Sainte-Barbe-du-Tlélat to Sidi-Bel-Abbès and Ras-el-Mâ, from Tabia to Tlemcen and the border of Morocco, and from Blida to Djelfa.

The agreement is approved by the law of 11 December 1922.

Thus, in 1922, only two railway companies remained in Algeria: the Algerian State Railways Company (CFAE) and the Paris-Lyon-Mediterranean Company in Algeria (PLMA).

Network Expansion

Electrification of the mining line

Route of the Bône to Tébessa line in 1933.

The Souk Ahras to Tébessa line, granted to the Compagnie des chemins de fer Bône-Guelma in 1885, originally aimed to connect two important cities in eastern Algeria and ensure a connection with Tunisia, where the company also had concessions. It also had a strategic military interest due to its proximity to the border. Its construction was completed in 1888. Originally, it was a meter-gauge line given the expected limited commercial role.

The discovery in the 1890s of phosphate deposits in the Djebel Kouif (east of Tébessa, 257 km south of Bône) and iron ore in the Ouenza massif (located east of Oued Keberit at 190 km from Bône) at the same time led their operators to build short lines to connect these mining sites to the Souk Ahras to Tébessa line. These branches allowed the transportation of ores by rail to the port of Bône for export.

During the 1920s, the tonnage of ores transported by railways increased from 350,000 t (340,000 long tons; 390,000 short tons) in 1921 to nearly 2 million tons in 1930. The Bône to Tébessa line now played a crucial role in ore transportation. However, the operation of steam locomotives on a single track with a mountainous profile, including steep grades in the Souk Ahras region, became increasingly challenging and no longer allowed efficient transportation. The section of the line between Duvivier and Oued Keberit became a bottleneck limiting its capacity. Only the electrification of the line allowed an increase in capacity and tonnage through improved traction power of electric locomotives and increased speed. The decision to electrify the line was made in 1929, initially for the Duvivier–Oued Keberit section and later for the rest of the line in subsequent years. The voltage of the current chosen was 3 000 V DC, supplied by a thermal power plant of 43,000 kW (58,000 hp) located near Bône. The Algerian State Railways Company acquired around thirty locomotives of the CC 6-AE type (similar to PLM 1CC1 3700) built by Constructions électriques de France (CEF) in association with Alsthom.

The 6-AE electric locomotives remained in service until 1972, and the Bône–Tébessa line remained the only electrified line in Algeria until the 2000s when the suburban network of Algiers was electrified.

Establishment of the Algerian Railways Office

The creation of the Société nationale des chemins de fer français (SNCF) in 1938 notably led to the disappearance of the Paris-Lyon-Mediterranean Railway Company (PLM) and its Algerian subsidiary, the PLMA. In Algeria, there was initially consideration of integrating the entire network into the new SNCF. However, it was ultimately decided to establish a separate entity from the SNCF: the Office des chemins de fer algériens (CFA), which officially began operating the railway network in Algeria on 1 January 1939.

From World War II to independence

Rail transport in Algeria, like in metropolitan France during the same period, faced competition from road transport, both for passengers and goods. Buses and trucks were more competitive and flexible for short or medium distances compared to trains. This situation, which emerged before World War II, continued until the early 1950s. It led to the closure of less important lines and the abandonment of those planned in previous plans.

Over the two decades preceding the independence of Algeria, the Algerian railway network did not undergo major changes except for some transformations of existing lines.

Line closures

Several small lines in Oran were closed:

• The lines from Sidi Bel-Abbès to Tizi and from Mascara to Uzès-le-Duc.
• The lines from Relizane to Uzès-le-Duc and from Uzès-Ie-Duc to Prévost-Paradol.
• The Burdeau to Hardy line, which remained with a gauge of 600 mm (24 in).
• The Oran to Damesme line.
• The Mostaganem to Relizane line.
• The Modzbah to Marhoun line.
• The Tlemcen to Beni-Saf line.
• The Oran to Hammam Bou Hadjar line.

The same fate befell lines in the central and eastern regions:

• The lines from Orléansville to Ténès, from Bouira to Aumale, and from Dellys to Boghni.
• The suburban lines of Algiers (former CFRA lines).
• The Constantine to Oued-Athménia line and the Bône to La Calle line.

Also, branch lines from the Biskra to Touggourt line:

• From Oumache to Tolga in 1953.
• From Still to El Oued in 1957.

Transformations and extensions of existing lines

The main transformations involved converting narrow-gauge lines to standard gauge:

• The meter-gauge line from Oued Keberit to Tébessa and Kouif was converted to standard gauge.
• The meter-gauge line from Biskra to Touggourt was converted to standard gauge in 1958.
• The narrow-gauge lines with an 1,055 mm (41.5 in) gauge from Arzew to Mostaganem and from La Macta to Perrégaux were converted to standard gauge.

In 1942 the Trumelet to Burdeau section of the Trumelet to Hardy line, with a 600 mm (24 in) gauge, was converted to narrow gauge with a 1,055 mm (41.5 in) gauge.

In 1946 a 145 km (90 mi) branch line with a 600 mm (24 in) gauge was created on the Biskra to Touggourt line between Still and El Oued. The line was converted to a meter gauge in 1950 and closed in 1958.

Establishment of the National Company of French Railways in Algeria

On 1 January 1960 the Société nationale des chemins de fer français en Algérie (SNCFA) was created, with the French state and the metropolitan SNCF as its two shareholders.

Independent Algeria period

From Independence to the end of the 20th century

On January 16, 1963, the French National Railway Company in Algeria, created in 1959, becomes the Société nationale des chemins de fer algériens (retaining the same acronym SNCFA).

After independence the new SNCFA inherited a fairly dense, heterogeneous, and partly obsolete network. It also needed to "Algerianize" its workforce to hastily replace French-born railway workers, mainly executives, who had left Algeria. In 1963, the full Algerian operation of the network took place thanks to a few engineers and supervisors who met this challenge. However, that year, passenger and freight traffic represented only 68% and 51% respectively compared to 1960.

For an entire decade, from 1962 to 1972, the SNCFA focused on maintaining its lines and equipment. During this period, narrow-gauge lines were closed either for economic reasons or due to difficulties in maintenance or renewal of rolling stock. The notable exception was the extension of the Annaba to Tébessa line in 1966, covering a length of 110 km (68 mi) to the Djebel Onk phosphate mine.

French railway equipment was retained for about ten years. It began to be gradually replaced from 1972 onwards:

• 32 diesel locomotives, ordered from the former East Germany, replaced the forty-year-old CC 6 AE locomotives of type Co'Co' delivered in 1932;
• 33 railcars from Fiat with 780 hp (580 kW), equivalent to the FS ALn 668, replaced French railcars and some towed trains;
• 29 diesel-electric locomotives with 3,300 hp (2,500 kW), of type CC, were delivered by General Motors.

Establishment of the National Company of French Railways in Algeria

On March 31, 1976, at the end of the French State's concession, the Algerian State divided the SNCFA into three distinct entities:

• the National Company for Rail Transport (SNTF), responsible for the operation and maintenance of the railway network;
• the National Company for the Study and Realization of Railway Infrastructure (SNERIF), responsible for the renewal and extension of the railway network;
• and SIF, the engineering and realization company for railway infrastructure.

A new investment program allowed the construction of 203 km (126 mi) of new lines, the doubling of 200 km (120 mi) of tracks (from Algiers to Thénia, from El Guerrah to Constantine, and Didouche Mourad), and the renewal of 1,400 km (870 mi) of tracks and ballast.

In 198, the financial crisis led to the dissolution of SNERIF and SIF, with their prerogatives taken over by SNTF, which changed its status in 1990 to become a Public Establishment with Industrial and Commercial Character (EPIC).

The network at the end of the 2000s

During the Algerian Civil War between 1991 and 2002, the network experienced numerous attacks on passengers and sabotage of infrastructure, making its operation difficult and dangerous. However, SNTF and its staff managed to maintain the circulation of passenger and freight trains throughout this period.

At the end of the 20th century the Algerian railway network comprised 4250 km of lines, of which 4219 km were operational, with characteristics described in the table below.

Gauge		Electrification		Number of tracks
Standard Gauge	3,169 km (1,969 mi)	Electrified	301 km (187 mi)	Double Tracks	345 km (214 mi)
Narrow Gauge	1,081 km (672 mi)	Not Electrified	3,949 km (2,454 mi)	Single Track	3,905 km (2,426 mi)

The network consists of four groups of lines:

• the North Loop: Eastern border–Annaba–Constantine–Algiers–Oran–Tlemcen–Western border (standard gauge lines);
• feeder lines: Guelma, Skikda, Jijel, Bejaïa, Tizi-Ouzou, Mostaganem, Arzew, Aïn Témouchent, Ghazaouet (standard gauge lines);
• the East Mining line: Annaba–Djebel Onk, Oued Keberit–Ouenza/Bou Khadra (standard gauge and electrified);
• penetration lines towards the High Plateaus and the South:
  • El Guerrah–Touggourt (standard gauge);
  • Blida–Djelfa; Relizane–Tiaret; Mohammadia–Béchar (narrow gauge).

Beginning of the 21st century

Network expansion and passenger rolling-stock renewal

In the early 2000s, after the challenging period of the civil war, the Algerian government and SNTF (National Railway Company) initiated programs to modernize the railway network.

In 2005 the National Agency for Studies and Monitoring of Railway Investment (ANESRIF) was established to manage a new public investment program with the goal of expanding the network to 12,500 km (7,800 mi) by 2025.

In the late 2000s and early 2010s, the Algiers suburban lines were electrified, and nearly 340 km (210 mi) of new lines were commissioned:

• From Aïn Touta to M'Sila in 2009
• From Aïn M'lila to El Aouinet in 2009
• From Bordj Bou Arreridj to M'Sila in 2010

Concurrently with the modernization and expansion of its network, SNTF began renewing its passenger rolling stock by acquiring diesel, electric, or diesel-electric automotor trains to replace trains composed of old passenger cars pulled by diesel locomotives. The acquisitions included:

• 17 diesel automotor trains from CAF (Class ZZ 22) for regional services, delivered from 2007;
• 64 electric automotor trains Stadler FLIRT (Class 541) for the Algiers suburban network, delivered from 2008;
• 17 bi-mode electric and diesel automotor trains Alstom Coradia (Class ZZe) for long-distance services, delivered from 2018.

In 2015, out of a 2,300 km (1,400 mi) program for new lines, 1,324 km (823 mi) were under construction, with the majority focused on the western part of the Rocade des Hauts Plateaux.

On September 10, 2018, ANESRIF inaugurated the GSM-R railway telecommunication system for the first time in Africa. This telecommunication system aims to secure communications on an autonomous network between the center in Algiers and trains, as well as between trains and operators responsible for maintaining the network.

In the late 2010s and early 2020s the Algerian railway network expanded with the opening of lines:

• From Birtouta to Zéralda, in 2016;
• From Moulay Slissen to Saïda, 2017;
• From Tissemsilt to M'Sila, in 2022;
• From Saïda to Tiaret, in 2023.
