Abstract: In view of the crucial role, railways have played historically inland transportation, the West African region still endure to provide an efficient transport system. While road transport has been almost the exclusive predominant transportation mode in the region, the railway is now showing a global comeback. In the absence of a new phase of modernization at the international standard, it is unavoidable that the high demand for mobility of its increasing population and the full exploitation of its natural resource endowment will be constrained. This study presents the past, present, and future developments of the railway sector. The first section includes the brief historical development of the railways, the determinants choices of their location, and the influential parameters for their construction. The second section deals with the present state of the railway infrastructure, operational performance, and railway sector institutions. The last section provides some recent investment in the key construction projects at a national level.
Keywords: West African railways, transportation, road transport.
1. Introduction
A global renaissance has recently been felt in railway transportation through the total length of its network and annual traffic units. This revival of the railways is pertaining to their considerable socio-economic, environmental costs and benefits generated by the transport sector (Bayane & Yanjun, 2017). As a consequence, an absolute corporation for railways is a precondition for transportation operation services since it remains the principal mover of people and heavy freight over the middle to long distances. There is an opportune chance to develop railway when combining the apparent economic growth in West Africa in addition to the arisen middle class and unutilized resources (Olievschi, 2013). Thus, the extension of the railway network has been decided by the African Union to meet the aspiration of its agenda by 2063 (A. Union, 2015).

The objective of this paper is to present the past, present, and future development of the railway transportation system in West Africa. The past or background of the railway transportation system covers the historical development of railway construction, the determinants of the choice of railways location and the influential parameters of railway construction. The present state of the railway covers its infrastructure (track density and operated gauges), operational performance (traffic density and labor productivity), and railway sector institutions. The future development comprises of investment and key construction projects on the railway sector.
2. Methodology
The methodology in this paper consists of the utilization of major sources from a practical survey, analysis of evidence from the experimental study as well as analysis of data from different published sources. The list of selected countries consists of Benin Republic, Burkina Faso, Ghana, Guinea, Ivory Coast, Liberia, Mali, Nigeria, Senegal, Sierra Leone, and Togo.
3. Background of railway transportation
3.1. Historical development of railway construction
In West Africa, the construction of the first rail line started from Dakar to St Louis Dakar at the mouth of the Senegal river in 1885 (Ogunremi & Faluyi, 1996). The Dakar-St Louis line got to Bamako (Mali), 1159 km inland, in 1923 (Ogunremi & Faluyi, 1996). In Ivory Coast, the railway construction began in 1903 and the line got to Bouake, 315 km inland, in 1912 (Ogunremi & Faluyi, 1996). In Burkina Faso, Ferkessedougou (558 km) and Bobo Dioulasso (796 km) were reached in 1926 and 1934 respectively but the line never got to Ouagadougou at this time (Ogunremi & Faluyi, 1996).
Railway in the Benin Republic (previous Dahomey) was built between 1905 and 1913 (Pobè to Porto-Novo line) and was extended to Cotonou, 106 km in all, between 1928 and 1930 (Bouraima & Qiu, 2018). As for Togo, three metrics gauge lines were constructed by the Germans: the central line from Lomé to Atakpame, 1934; the Lomé-Aného and Lomé-Kpalimé lines (Ogunremi & Faluyi, 1996). In Nigeria, construction started in Lagos in 1898 and the line was extended to Ibadan in 1901, Jebba on the Niger in 1909 and Kano, 1145 km inland, in 1911 (Ogunremi & Faluyi, 1996).
In Ghana (Gold Coast), the construction of railway proceeded from Accra in stages: Tarkwa was reached in 1901 and Obwasi in 1902 (Ogunremi & Faluyi, 1996). The Accra-Kumasi and Accra-Sekondi lines were accomplished in 1923 and 1927 respectively (Ogunremi & Faluyi, 1996). A meter-gauge railway line was built from Conakry to Kankan, in inland Guinea close to the Mali and Ivory Coast borders, in 1914 (Metcalfe, 1916). In Sierra Leone, the first railway in British West Africa was built in 1896 linking the fine harbor at Freetown to Pendembu, a distance of 366 km (Metcalfe, 1916). In Liberia, with a total length of 490 km, three long-distance railway lines comprise of a Mano River line running from the river border with Sierra Leone inland to Monrovia, another running from Bong County to Monrovia and a third from Yekepa in Nimba Country to the port of Buchanan were respectively built in the early 1960s (Graham, Garrido, & Karjanlahti, 2012).
3.2. Determinants of the choice of railways location
The construction of railways was governed by different factors. As the wealth of West Africa is immense, and inhospitable coasts and few good harbors have characterized its transportation system, the first practical consideration which motivated the construction of the railway is the question of ports (Captain H.O. & Mance D.S.O., 1913). In West French Africa, the transcontinental railway networks were thus projected by colonial governors aiming at serving the ports as feeders and link to the countries of the hinterland (Debrie, 2001). The penetration and conquest of French and British colonial governments in West Africa have resulted in several footholds for them along the Guinea Coast through seaports and feeders' railways.
Compare to British power, most of the territories were under French control which explains a number of rail lines that serve ports on the Western and Southern coasts (Dakar-Niger, Abidjan-Niger, and Benin-Niger), and railways connection between Senegal and Mali, and Ivory Coast with Burkina
Faso. On the British side, the constructed rail lines were connecting with the coastal terminals at the major port of Tema in Ghana, Lagos and Port-Harcourt ports in Nigeria, the port of Freetown in Sierra Leone, and the port of Monrovia in Liberia.
Prior to the attainment of their independence in West Africa, numerous countries were endowed with one or other forms of mineral resources. In addition to natural resources, most of them are known to be largely dependent on rich agricultural potential. This immense wealth of West Africa in terms of agricultural products and minerals has thus become a spur of rapid construction of transport lines for export during the colonial period. As a matter of fact, natural resource exploitation was the main reason for rail penetration (Taaffe, Morrill, & Gould, 1963).
In the case that railways systems are under different administrative control, there is an occurrence of harsh competition between them. For instance, neighbors and rivals, the French and Germans colonial powers built parallel rail penetrating from narrow openings on the Gulf of Guinea: Cotonou-Parakou line meets Lomé-Sokodé line (Pourtier, 2007).
When looking at the colonial railway networks, the early construction was following the route with cheaper and modest investments (Rémi Jedwab, Kerby, & Moradi, 2017), which could explain that the physical configuration with the higher ultimate expense for construction was avoided (Jaekel, 1997). This explains the avoidance of deep cuttings, long-span bridges, tunnels and viaducts, and high embankments. The Baro-Kano railway line in Nigeria is an illustration, where British colonial power has considered lower-cost construction and the best possible grade with the easy ability of improvement as traffic increased (Sunderland, 2017).
The delimitation of the territory was also considered as another factor when the railway system should be constructed, as the West Africa region is mostly fragmented between different colonial superpowers. Prior to the construction of the railway which is considered as colonialists' first ally, colonial engineers used to imposed their order on the unknown African landscape, control times and distances within the unspecified territory (Scotto, 2018), which will avoid the difficulties or confrontation from different colonial powers as it was the case on the French Guinea railway construction between British and French (Thomas, 1957).
3.3. Influential parameters of railway construction
During the colonial period, the construction of the railway was undertaken by the colonial governments, since it was seen as an instrument of effective occupation (Mabogunje, 2015). The construction of the railway in Senegal was planned to secure for France the basin of the upper Niger, to extend colonial control and expand the economic exploitation of French West Africa (AOF), and to facilitate the penetration of West Africa in the south of Sahara (Robinson, 2007). The Ivory Coast railway was undertaken to link Grand Bassam to Kong (important caravan center), and give a maritime façade to the territory already occupied in Sudan (Brou, 2015). The railway was extending to Burkina Faso in order to have access to the territory (Nana, 1984). It is the same scenario in the Benin Republic (previous Dahomey), where access to hinterland countries was among the motivation of railway construction (Bouraima & Qiu, 2018). In Liberia, lines were originally built mainly to transport iron ore from the mine heads in the Western cluster and in Bong to the port of Monrovia as well as from the mines in Nimba (near the Guinea border) to the port of Buchanan (Graham et al., 2012). However, this effective occupation by colonial powers that motivated the construction of the railway through the region was temporary.
Another factor based on the economic grounds was taken into account since it was strategic and will mostly impact the order in which the component projects were accomplished. The case of Nigeria is an example where the original conception of the railway was to consolidate power in the newly acquired territory, and opening up of the country to trade with England (Ademiluyi, 2006). As for the development of commerce and commercial agriculture, northern Nigeria was linked to the southern part, which improves the country's prosperity through the expansion of its market product and enhances productivity (Adesanya, 2010). The administration reason through the intercommunication between different areas of the same colonial administration was also among the object of railway construction. In Nigeria, the railway was constructed to link the central seat of the colonial government in Lagos with other parts of the country (Agbaeze & Onwuka, 2014).
4. State of rail infrastructure in West African countries
4.1. Overview
Although the railways have the capacity to be more advantageous where substantial savings enable, West African countries have wrestled to obtain the profits. The common appearance of railways in West African countries mirrored deteriorated infrastructure, obsolete technologies, and low-quality operations regarding safety and performance (Bayane, Yanjun, & Bekhzad, 2020). This can be explained by the fact that the national transport sector plan has favor road transport mode over its rail counterpart. This undoubtedly explained why more funds are given to road transport instead of the railway because of its sustainability and immediate operation (Bouraima & Dominique, 2018). After many years of inadequate maintenance and scarcely accessible investments, most of the countries within the region have main railways sections that are inoperable and necessitate renovation. Overall, the railway infrastructure in West Africa is in poor condition. For instance, the Cotonou-Ouidah, Pahou-Segbohoue, Cotonou-Pobe, viz Porto-Novo and Abomey-Zagnanado via Bohicon lines are not operational in the Benin Republic; the 104-kilometer section between Ouagadougou and Kaya are out of service since 2003 in Burkina Faso (Bayane et al., 2020). As for Ghana, except the Accra to Tema, Accra to Kotoku, Awaso to Dunkwa and south to Takoradi lines, 60% of the total railway network are inactive (Bullock, 2009).
The poor quality and the deficient size of the network has exceptionally affected the regional network of landlocked countries of Burkina Faso, Mali, and Niger and inflicted huge freight costs for three reasons. First of all, the limited length and quality of the railway lines decreased the freight volumes that line should bear, influencing severely efficiency and labor productivity. Next, the restricted length of rail routes shows that freight has to be shifted to road transport in order to get the final destinations, which raises the costs in comparison to only road transport mode. Lastly, a variety of track gauges experienced within the region contribute to the hindrance of a balance traffic flow on the railway networks.
4.2. Infrastructure
In West Africa, freight is principally being transported on the railway infrastructure (Fig. 1) because of the innumerable natural and mineral resources that characterized many countries of the region. As 90% of regional importation and exportation traffic are conveyed through the sea, most of the railway lines are connected to mining zones and ports (AfDB, 2015). Nevertheless, there is a restriction in the transportation of people and goods in the region because of the small connectivity between national railway networks. Only a smaller number of lines traverse borders, such as Sitarail between Burkina Faso and Ivory Coast, and Transrail between Mali and Senegal. A variety of track gauges ranging from narrow (600mm) to standard (1435mm) operated in several countries. Metric gauge lines of 1000 mm are mostly used in all French-speaking countries while the Cape gauge (1067mm) predominates in English speaking countries (Gwilliam, 2011), followed by the standard gauge (1435mm), which are more recently constructed. Figure 2 showed the operated track gauges found in the Western region of the continent. Attempts in constructing modern tracks gauge appear to overlook interest in existing infrastructure.
Literature available so far indicates that not only track quality but also its density is beneath international standards in West Africa. Most of the railway's assets are more than a century old, and as a consequence, the quality of their track materials is significantly obsolescent (Bayane et al., 2020). All the early railway tracks in West Africa are ballasted; however, they are not properly or habitually maintained. The combined effect of aging infrastructure, tamping and deficient maintenance has seriously impacted the operational performance of railways in the region. Firstly, the maximum axle load that the railway structure can bear in West Africa is roughly 17 tonnes (Bayane et al., 2020). Comparatively, the standard axle load in European countries is greater than 25 tonnes (E. Union, 2004). The poor track quality influences the maximum speed achieved in these networks. According to (Bayane et al., 2020), the freight trains in West Africa reached only an average speed of 30km/h.

Practically all the networks are single track except the 70 km double track of Dakar-Thies line in Senegal, and the first 30.6 km of the Western line (Takoradi-Manso) in Ghana (Bayane et al., 2020). Diesel locomotives are used in the existing railway tracks because of a lack of electrification in their networks. The platforms and sidings are obsolete and have existed since the construction of the first original lines. Signaling on railway networks is mostly done through manual systems whether with manual train's orders or mechanical signals (Bayane et al., 2020). The adequacy of manual systems is obvious in the very low traffic actually made on most lines, however, safety problems often happen because of human error. Signaling systems are determined as an obstacle that needs to be controlled in order to increase the traffic without danger.

4.3. Operational performance
The railway traffic in West African countries is mostly freight services that represent almost a huge percentage of regional traffic. This is due to the difficulty to get back the costs of passenger operations because of a lack of subsidies and poor track conditions. The combined effect of low axle load and limited speed reached on most of the damaged existing lines has considerably affected the regional traffic volume. Traffic volumes are a fundamental scale of the viability and cost-effectiveness of operational railways because they underline the utilization of the infrastructure. The ability of rail transport to compete with other modes is based on the huge volume of traffic carried, which will produce large funds for infrastructure maintenance (Bayane et al., 2020). Bayane et al. (2020) in their study have shown that with exception of Guinea where the private mining companies significantly
used the railway's lines, the rest of the West African countries have a traffic density below 1 million traffic units (passenger-km plus tonne-km) per route-km (Fig. 3).

Also, low labor productivity has been noticed due to low traffic volumes (Fig. 4). Safety along the railway network has been another issue. Worse state of safety records through derailments and thievery of infrastructure have been highlighted based on the available data (Bayane et al., 2020).
4.4 Railway sector institutions
Powerful institutional and regulatory frameworks that secure investment are primordial for the development of the railway. Adequate regulations and policies are implemented and formulated based on the degree of involvement of government actors in the railway industry. Some countries have established the regulation and legal system in order to monitor market performance, safety issues, and corruption. While some countries like Ghana and Nigeria have enacted Act 2008 and Act 1955 for the establishment of their railway corporations respectively, the railway in the Benin Republic is still public enterprise without any regulatory body. The institutions of the railway sector of each country within the region are presented in Table 1.

5. Future railway development
As stated above, much of West African's existent railway infrastructure is mostly inherited from the British and French colonial period. After independence, nonetheless, the increasing costs of corruption and government bureaucracy, together with the decrease applicability of agricultural exports, meant that network progressively deteriorated. As stated by Remi Jedwab and Storeygard (2019), transport infrastructure in Africa is characterized by a restricted network, poor condition, and operated below design capacity, which worsens transport challenges for inland countries with export prospects. Recently, after decades of neglect, many Africans governments have sought the participation of a number of actors in this effort. Organization for Economic Co-operation and Development (OECD) investors, conventional Official Development Assistance (ODA), and non-OECD countries have mostly funded African infrastructure (Foster, Butterfield, & Chen, 2009). In the railway sector, the development comprises the rehabilitation of existing railway lines and the construction of a new railroad.

In the Benin Republic, the rehabilitation of 438 km of the railroad from Parakou to Cotonou, and the extension of remained 450 km to be built to reach 594 km of the planned route from Nigerien capital (Niamey) to Northern Benin (Parakou) is assigned to China Railway Construction Corporation (CRCC) at a cost of $ 4 bn (L. M. Afrique, 2018). In Burkina Faso, the modernization of the infrastructure and the increase of the rail network capacity will be undertaken by the Bolloré group over a 5-year period at a cost of CFA franc 262 bn (BIRBA, 2015). In addition to infrastructure-related investments, the group has also committed around CFA franc 20 billion to renew the rolling stock, in order to increase the FASO traction capacity of freight trains (BIRBA, 2015).
In Ghana, the revamping and transformation of the railway sector are designed by the Ghana Railway Master Plan (RMP) and include the rehabilitation, improvement, and modernization of the existing railway infrastructure; the expansion of railway infrastructure to other parts of the country and linking with neighboring countries such as the Ivory Coast, Togo, and Burkina Faso; and the interconnection of railway infrastructure with other modes of transportation (inter-modalism) (GRDA, 2013). The expansion of the national railway network will be realized by the construction of new standard gauge lines to ensure a more complete transportation service for the whole country. The rehabilitation and this expansion will be developed in 6 phases interventions (GRDA, 2013). The first phase includes the rehabilitation of Western (Takoradi-Kumasi and Dunkwa-Awaso) and Eastern (Accra-Kumasi and Achimota-Tema) lines. The second phase involves the doubling of the two lines restructured in Phase 1, by constructing the standard gauge lines: Takoradi-Kumasi (2 W) and Accra-Kumasi (2 E) and the conversion to the standard gauge of the previously restructured track. The third phase involves the construction of the single track, standard gauge, and transversal lines for the routes
Tamale-Yendi, Fufulsu-Sawla, Techiman-Kwadwokurom, and Nyinahin-Kumasi. The fourth phase sees the construction of two single tracks, standard gauge lines. The first section of the line starts from Aflao, near the border with Togo and heads West, mainly along the coast of the Gulf of Guinea, connecting the important cities of Tema, Accra, Cape Coast, and Takoradi. The second section starts at Tarkwa and ends at Omanpe, near the border with the Cote D'lvoire. The fifth phase sees the construction of a single, standard gauge line that extends the original Western Line northwards to reach and connect the future mines. The line starts from Dunkwa-Awaso and extends as far as Techiman, Sawia, and Hamile. The last phase sees the construction of a single, standard gauge line heading east, near the border with Togo, that from Tema reaches the river port of Akosombo and then heads towards Ho and Yendi in the North.
The financial investments of all 6 phases of the Master Plan are estimated at a cost of $ 21.508 million for the infrastructures and $1254 million for the rolling stock (GRDA, 2013).
In Guinea, the Dapilon-Santou rail project is a new 135km-long railroad facility being built to connect the Santou mining zone and the Port of Dapilon in Guinea. At an estimated cost of $3bn investment from the SMB-Winning consortium, the railroad will enable faster and more efficient transportation of bauxite to the docks in high concentration, and help to expand the mining zone while reducing the corporate transportation cost. In addition, there is an agreement of the Chinese-backed international consortium to build a 650km Standard Gauge Railway (SGR) and a deepwater port at a cost of $14bn. This is in exchange for permission to mine a massive, untapped deposit of high-grade iron ore in the West African country.
In Ivory Coast, ceremonies were held to mark the formal start of work on a long-awaited project to rehabilitate the 1260 km Abidjan-Ouagadougou metre-gauge railway at a cost of FCFA 262 bn (J. Afrique, 2018). In addition, studies and funding research were carried out to assist numerous projects such as (i) the construction of the San Pedro-Bamako railway for the exploitation of minerals; (ii) the construction of the 338 km Ouangolo-Nielle-Sikasso-Bougouni railway at a cost of CFA franc 240 bn, including 86 km in Ivory Coast; (iii) the construction of the 181 km long Man-Nzerekore (Guinea Conakry) railway at a cost of CFA franc 127 bn; and (iv ) the "RAIL CITY" project at a cost of CFA franc 300 bn to revalue the landholdings of SIPF in Plateau district (J. Afrique, 2018).
In Liberia, the Nimba railway is due for rehabilitation under the terms of an MDA (Mineral Development Agreement) with Arcelor Mittal, the company which has resumed exploitation of the former LAMCO mines in Nimba (Graham et al., 2012). The government of Liberia is requiring that the line be reconstructed to allow for multiple uses, as a result of which the investment cost will be considerable. China Union is rehabilitating the Bong mines (formerly operated by German company Thyssen), for which it is operating the Bong railway with limitations. The capital expenditure required for the Bong railway and connected mineral pier in Monrovia is estimated at around $ 350 million and China Union will have the obligation to undertake this infrastructure investment (Graham et al., 2012). Consideration is being given to the construction of a new railway to the Putu range in the coming years to evacuate the large scale find of iron ore found in the Putu mineral deposit (Graham et al., 2012).
In Mali, the rehabilitation of the Dakar-Bamako line is categorized into four possible options: (1) rehabilitation of Dakar-Bamako metric gauge track to ensure minimum safety (traffic below 700,000 tones/year) at a cost of $ 144 million, (2) rehabilitation of Dakar-Bamako metric gauge track to ensure minimum traffic (traffic less than 3 million tones/year) at a cost of $ 280 million, (3) rehabilitation of Dakar-Bamako metric gauge track to ensure high traffic (traffic between 3 and 10 million tones/year) at a cost of $ 495 million, and (4) Change from metric gauge to standard gauge (traffic over 10 million tones/year) at a cost of $ 1.515 bn (BAD, 2014). In addition, the rail interconnection project was planned between the countries of Mali, Guinea, and Ivory Coast (Conakry- Kankan-Mandiana-Bougouni-Bamako) at a cost of $ 724.080 million (BAD, 2014).
In Nigeria, two significant standard-gauge rail projects are financed by the Chinese (Chen, 2018). The rehabilitation of the Western trunk line from Lagos to Kano is the first one and replaced the colonial track. Of the scheduled route, the 187-kilometer Abuja-Kaduna single-track SGR was first to be built in 2014, at a cost of $874 million. The 312-kilometer Lagos-Ibadan segment is the next in the construction process by the China Civil Engineering Construction Company (CCECC) at a cost of $1.2 bn. Financing for the $1.1 bn Kano-Kaduna segment is still under negotiation. The new coastal railway linking Lagos to Calabar, via Warri and Port Harcourt, to include branch lines to Benin City and Onitsha is the second significant project. It was suggested by CCECC as part of three East-West routes that
would traverse the colonial trunk lines. The contract for the project is noted to be worth $11 bn and signed with CCECC in 2016. In April 2017, a loan request to the Exim Bank of China has been approved by the Nigerian senate and comprises $3.5 bn for the coastal project.
In Senegal, the revival of rail infrastructure is one of the major projects of President Macky Sall. Thus, clear prospects are emerging for the rail network within the framework of the Emerging Senegal Plan (PSE). The Dakar Regional Express Train (TER), which was put into service at the end of 2018 is its presidency flagship project (Afrique, 2016). Following the consecutive meetings in Beijing and Paris with the Advisory Group, an ambitious program to build 1,520 km of new lines has been drawn up, at a total cost of CFA franc 1.390 bn. The goal is to modernize railway infrastructure between Dakar and Thies and to build a double-track standard gauge, serving the Blaise Diagne International Airport (AIBD); to construct a new 1000 km structuring standard track gauge between Dakar-Tambacounda-Kedougou-Kenieba-Bamako, commonly called Dakar-Bamako by the South. In addition, the current Dakar-Tambacounda-Kidira-Bamako line will be completely rehabilitated. It is an extremely important corridor for supplying Mali with various products from transit operations at the port of Dakar, and for accessing the sub-regional market of the West African Economic and Monetary Union (WAEMU). Senegalese President Macky Sall promised to build a railway connecting Dakar to Ziguinchor, the capital of Casamance (southwest of the country) at a cost of $ 500 million (Ecofin, 2015).
In Sierra Leone, China Kingho Energy Group, one of China's largest privately-owned energy groups has planned to construct a 250-km railway from the northern Tonkolili district to the coastal town of Sulima at a cost of $ 6 bn (Angel, 2014). At present, Togo Rail is extending the Kpalime line to Aflao in Ghana. This project also requires the rehabilitation of the Lome-Kpalime line linking the Tokoin water tower and the Totsi/Djidjole junction (about 3 km) (JICA, 2013). The new line length in Togo is 2 km, that in Ghana is 2 km and the total including sidings in Aflao is 8 km. The cost is estimated at CFA franc 1,300 million. Another line extension project connecting Blitta to Ouagadougou under the Africa rail project is planned, aiming at constructing 761 km of new railway lines to interconnect their existing (JICA, 2013).
6. Conclusion
Sustainable railway transport has proved to play a crucial role than road mode when socioeconomic and environmental costs are considered. The greenhouse gas emission per passenger-km and tonne-km is seen to be reduced for railway transport in contrast to the road. This paper describes the past, present, and future development of the railway transportation system in West Africa. The current situation of railways shows their obsolescence state because of a lack of maintenance and limited investment. As a consequence, railways networks in this region have been characterized by low traffic densities which reduce their competitiveness against the road transport mode. In recent years, the sector has shown a global revival through the rehabilitation of existing lines and the construction or planning of new lines.
