DRC Segment — Connecting the World's Richest Mineral Province

Segment Overview

The DRC segment of the Lobito Corridor is the corridor's main operating constraint. LAR describes the Luau-to-Kolwezi access section as 450 kilometres under a track-access agreement with SNCC, while the broader SNCC network continues from Kolwezi toward Lubumbashi and Sakania. The segment traverses the southern DRC's Katanga mining province — a geological formation that contains the world's largest reserves of cobalt, globally significant deposits of copper, and increasingly important reserves of germanium and tin. The corridor's economic logic depends on whether this DRC interface can be rehabilitated and governed well enough to give miners a faster, cheaper, and more reliable route to the Atlantic Ocean.

The DRC segment follows the route of the Chemin de fer du Katanga, one of several railway networks operated by the Société Nationale des Chemins de fer du Congo (SNCC), the DRC's state railway company. Unlike the Angolan segment, where the Lobito Atlantic Railway (LAR) consortium holds a 30-year concession, the DRC infrastructure remains part of the SNCC system. LAR's public materials describe a track-access agreement with SNCC for the 450-kilometre Luau-Kolwezi section and support for modernising the remaining railway network in DRC territory. Current official sources do not disclose a full DRC concession equivalent to LAR's Angolan concession.

Rehabilitating this segment requires not merely fixing track and procuring locomotives, but restructuring the institutional relationship between SNCC, the Congolese state, international financiers, and the mining companies that generate the freight demand the railway must capture. It is simultaneously an engineering project, a governance reform challenge, and a diplomatic negotiation — all conducted in one of the world's most complex operating environments.

Route & Geography

The DRC segment can be understood as two distinct sub-segments joined at Kolwezi, each with different characteristics, infrastructure conditions, and rehabilitation requirements.

Western Access Section: Luau/Dilolo to Kolwezi (~450 km in LAR materials)

The western access section connects the Angolan border at Luau/Dilolo to Kolwezi, the self-proclaimed cobalt capital of the world. LAR gives the section as 450 kilometres. This portion of the railway traverses relatively flat savanna terrain at elevations between 1,000 and 1,300 meters, crossing waterways in the Lualaba system. The landscape is characterized by miombo woodland, seasonal wetlands, and scattered agricultural settlements.

This sub-segment is the critical missing link in the corridor's east-west connectivity. It is the stretch that connects the rehabilitated Angolan railway to the DRC's mining heartland, and its condition will determine whether minerals from Kolwezi and surrounding mines can reach the Port of Lobito by rail rather than by the circuitous truck-and-rail combinations currently used. Track conditions on this sub-segment are among the worst on the entire SNCC network. Sections of rail date to the Belgian colonial era, with jointed rail on timber sleepers that have deteriorated beyond economical repair. Ballast has been depleted or contaminated, drainage structures are blocked or collapsed, and several bridges require complete reconstruction. Speed restrictions of 10 to 15 kilometers per hour apply on multiple sections, making the 420-kilometer journey a multi-day ordeal for freight trains.

Eastern Sub-Segment: Kolwezi to Lubumbashi (~430 km)

The eastern sub-segment stretches approximately 430 kilometers from Kolwezi through Fungurume, Likasi, and onward to Lubumbashi, the DRC's second-largest city and the commercial capital of Haut-Katanga Province. This is the more densely populated and economically active portion of the DRC segment, passing through or near virtually every major mining operation in the Katanga Copperbelt. The terrain is gently undulating savanna plateau at elevations of 1,200 to 1,500 meters, with laterite soils and scattered kopjes.

The Kolwezi-Lubumbashi mainline is the backbone of SNCC's freight operations in Katanga. Despite its strategic importance, the line carries only a fraction of the mining output produced along its route. Most copper cathode and cobalt hydroxide produced in the Kolwezi-Likasi-Lubumbashi mining belt is transported by truck to Lubumbashi and then onward by road to the DRC-Zambia border crossing at Kasumbalesa. From there, minerals travel southward through Zambia to the ports of Durban in South Africa or Dar es Salaam in Tanzania, journeys that routinely take 30 to 45 days and cost $150 to $250 per tonne. The failure of the Kolwezi-Lubumbashi railway to capture this freight is a direct consequence of SNCC's operational dysfunction: miners do not trust the railway to deliver their product on time, intact, and without pilferage.

Key Intermediate Stations

SNCC Partnership

Any discussion of the DRC segment must grapple honestly with the condition and institutional reality of SNCC, because SNCC is not merely the operator of the railway line — it is the railway line. All rail infrastructure, rolling stock, stations, depots, and rights-of-way within the DRC belong to SNCC under Congolese law. No rehabilitation, investment, or operational improvement can proceed without SNCC's institutional participation and the Congolese government's political authorization.

Institutional Deterioration

SNCC's decline is one of the most dramatic stories of infrastructure collapse in modern Africa. At its peak in the late 1970s, the railway company (then known as SNCZ under Zaïre) operated approximately 5,000 kilometers of track, employed over 30,000 workers, and moved more than 3 million tonnes of freight annually across the DRC's southeastern mining regions. By the 2020s, SNCC's functional network had shrunk to fewer than 2,000 operational kilometers, annual freight volumes had collapsed to between 200,000 and 400,000 tonnes, and the company's workforce, while still numbering in the thousands, had become largely unproductive due to unpaid wages, outdated skills, and the absence of functioning equipment to operate.

The causes of SNCC's deterioration are structural and deeply embedded. During the Mobutu era (1965–1997), railway revenues were diverted to political patronage networks rather than reinvested in maintenance and equipment. The two Congo wars (1996–1997 and 1998–2003) destroyed infrastructure, displaced workers, and severed supply chains for spare parts and consumables. Post-conflict governments inherited a railway system already in terminal decline and lacked both the fiscal resources and the political will to fund its rehabilitation. Foreign aid programmes, including World Bank and African Development Bank interventions, provided episodic funding for specific rehabilitation projects, but these efforts repeatedly failed to produce sustainable operational improvements because they addressed physical infrastructure without reforming the institutional dysfunction that had caused the deterioration in the first place.

Operational Constraints

The operational reality of SNCC's Katanga network in its current state presents severe constraints that the Lobito Corridor project must overcome. Locomotive availability is critically low: of the roughly 60 to 80 diesel-electric locomotives nominally in SNCC's Katanga fleet, fewer than 15 are typically operational at any given time. The remainder are sidelined by mechanical failure, lack of spare parts, or the absence of qualified technicians to perform repairs. Freight wagons are in equally dire condition, with a functional wagon fleet that can support only a fraction of the demand generated by the mines along the route.

Track conditions impose severe speed restrictions across the network. On the Dilolo-Kolwezi sub-segment, maximum operating speeds are restricted to 15 to 20 kilometers per hour for freight and 10 to 15 kilometers per hour on the most degraded sections. Even on the relatively better-maintained Kolwezi-Lubumbashi mainline, speeds rarely exceed 25 to 30 kilometers per hour. At these speeds, a journey from Kolwezi to Lubumbashi that should take 8 to 10 hours by rail takes 24 to 36 hours or more, with unscheduled stops for breakdowns adding further unpredictability. Signaling systems are almost entirely non-functional, with train movements managed by manual communication methods that limit line capacity and compromise safety. Derailments occur regularly, further disrupting schedules and damaging both rolling stock and track.

The SNCC-LAR Partnership Framework

The Lobito Corridor initiative has necessitated a new partnership framework between SNCC and the Lobito Atlantic Railway consortium. Under the arrangement that has been negotiated, LAR provides capital investment, technical expertise, and operational management support for defined sections of the SNCC network that form part of the corridor route. SNCC retains ownership of the infrastructure and continues to provide certain operational services, including workforce deployment and local regulatory compliance. The partnership is structured as a cooperative agreement rather than a full concession, reflecting the political sensitivity of granting a foreign consortium direct control over DRC railway assets.

The original LAR concession materials refer to $100 million of sponsor investment linked to the DRC side of the corridor. The larger DRC rehabilitation structure changed materially after this page's previous update: on 5 December 2025, the US DFC announced a letter of interest with Mota Engil Engenharia e Construção África S.A. for the rehabilitation, operation, and transfer of the Dilolo-Sakania railway line in the DRC. DFC said the project may seek up to $1 billion in financing following full review. This is an LOI, not a closed loan, and DRC-side concession award and operating terms remain unresolved in official disclosures reviewed for this update.

The SNCC-LAR partnership must navigate a complex set of institutional, political, and labor challenges. SNCC's workforce includes thousands of employees whose productivity is limited but whose political significance is considerable. Any restructuring that results in job losses will face resistance from unions, provincial politicians, and the communities that depend on SNCC employment. At the same time, LAR cannot achieve the operational performance standards its investors require without fundamental changes to how trains are crewed, dispatched, and maintained. Negotiating this balance between institutional reform and political reality is among the most delicate challenges facing the entire Lobito Corridor project.

Rehabilitation Plan

The rehabilitation plan for the DRC segment is organized into three overlapping phases, prioritized by their impact on corridor throughput and the availability of financing.

Phase 1: Kolwezi-Lubumbashi Mainline (2024–2027)

The first priority is restoring the Kolwezi-Lubumbashi mainline to a standard that can attract freight from the mining companies currently using trucks. This 430-kilometer stretch generates the highest potential revenue because it serves the densest concentration of active mining operations on the entire corridor. The rehabilitation scope includes complete track renewal on the most degraded sections (estimated at 40 to 50 percent of the total distance), ballast replacement and tamping on the remainder, bridge strengthening and waterway clearance, installation of modern signaling on at least the Kolwezi-Likasi section, and construction of new freight loading facilities at Kolwezi, Fungurume, and Likasi.

The target operational standard for Phase 1 is a maximum freight speed of 60 kilometers per hour, with an average operating speed of 40 to 50 kilometers per hour including station stops and loading operations. Achieving this standard would reduce the Kolwezi-Lubumbashi transit time from the current 24 to 36 hours to approximately 10 to 12 hours, making rail competitive with trucking on both cost and reliability. Target annual throughput on the rehabilitated mainline is 3 to 5 million tonnes, up from SNCC's current throughput of approximately 300,000 tonnes on the same route.

Phase 2: Dilolo-Kolwezi Rehabilitation (2025–2029)

The second phase addresses the western sub-segment from Dilolo to Kolwezi, the link that actually connects the DRC mining belt to the Angolan railway and, through it, to the Port of Lobito. This is the more technically challenging rehabilitation because the Dilolo-Kolwezi track is in worse condition than the Kolwezi-Lubumbashi mainline and passes through more remote terrain with limited construction support infrastructure. The rehabilitation scope is comparable in technical specification to Phase 1 but will require more extensive new construction, including complete replacement of track on sections where the existing formation has failed, reconstruction of multiple bridges, and installation of entirely new signaling and telecommunications systems.

Phase 2 completion is the milestone that transforms the Lobito Corridor from a concept into a functioning transcontinental transport route. Until the Dilolo-Kolwezi link is operational at modern freight standards, minerals from Katanga cannot reach Lobito by rail. Every timeline projection for the corridor's economic impact depends critically on when this phase is completed.

Phase 3: Capacity Expansion and Branch Lines (2028–2032)

The third phase focuses on expanding capacity beyond the initial rehabilitation standard and connecting additional mining operations through branch lines and spur tracks. This includes double-tracking of the highest-traffic sections between Kolwezi and Likasi, construction of new mine spur lines to operations not currently connected to the rail network, expansion of freight terminal capacity at Kolwezi and Lubumbashi, and installation of the full digital train management system that will integrate the DRC segment with the LAR-operated Angolan network.

Mine Connections

The DRC segment's economic viability depends entirely on its ability to capture freight from the mines that line its route. The Katanga Copperbelt hosts some of the world's most productive and valuable mining operations, and each represents a potential customer whose freight volumes could sustain the rehabilitated railway. The following table summarizes the major mines along or near the DRC segment, their distance from the nearest rail loading point, and their current and projected output.

Major Mines Served by the DRC Segment

Kamoa-Kakula: The Anchor Customer

The Kamoa-Kakula copper complex, operated by Ivanhoe Mines in joint venture with CITIC Metal and Zijin Mining, is the single most important potential customer for the DRC segment. The mine produced a record 437,061 tonnes of copper in 2024 and 388,838 tonnes in 2025 after a disrupted year, keeping it among the world's major copper operations. When its on-site smelter reaches full capacity, Kamoa-Kakula will produce blister copper anodes that must be transported to market — volumes that could fill multiple train loads per day. The mine is located approximately 25 kilometers from the Kolwezi rail station and has been actively engaged in discussions with LAR and SNCC regarding the construction of a dedicated spur line to connect its processing facilities directly to the mainline railway.

Ivanhoe Mines' founder, Robert Friedland, has been among the most vocal advocates for the Lobito Corridor, describing rail access to the Atlantic as transformative for the mine's logistics costs and competitive position. Currently, Kamoa-Kakula's copper output is trucked to Lubumbashi and then exported southward through Zambia — a process that adds significant cost and transit time. A functioning rail connection to Lobito would cut the mine's export distance to an ocean port by more than half and reduce logistics costs by an estimated 30 to 40 percent.

Tenke Fungurume and the CMOC Complex

The Tenke Fungurume mine, operated by CMOC Group (formerly China Molybdenum), is the world's second-largest cobalt producer and a major copper operation. Located near the town of Fungurume, the mine sits only approximately 8 kilometers from the mainline railway — one of the shortest mine-to-rail distances on the entire segment. Tenke Fungurume produced approximately 280,000 tonnes of copper and 28,000 tonnes of cobalt in 2024. CMOC also controls the nearby Kisanfu copper-cobalt deposit, which is being developed as a satellite operation approximately 30 kilometers from the Kolwezi rail station. Kisanfu holds one of the world's highest-grade undeveloped cobalt deposits and is expected to contribute substantially to CMOC's regional output as it ramps up production.

Glencore's Katanga Operations

Glencore operates two of the DRC segment's most significant mine complexes. KCC (Kamoto Copper Company), located just 5 kilometers from the Kolwezi rail station, is one of the world's largest copper-cobalt mines, producing approximately 270,000 tonnes of copper and 35,000 tonnes of cobalt annually. The Mutanda mine, approximately 12 kilometers from Kolwezi, was once the world's largest cobalt mine before Glencore placed it on care and maintenance in 2019 due to low cobalt prices. Mutanda has been restarting operations and is expected to return to significant production volumes as cobalt demand from the battery sector recovers. Together, Glencore's Katanga operations represent a massive potential freight source for the rehabilitated railway.

Manono: The Lithium Frontier

The Manono lithium-tin project, currently being developed by Zijin Mining, represents a different kind of opportunity for the DRC segment. Located approximately 350 kilometers north of the mainline railway near the town of Kamina, Manono is not directly served by the existing SNCC Katanga network and would require either a dedicated branch line or a road-rail intermodal connection to access the corridor. Manono hosts one of the world's largest hard-rock lithium deposits, and when it reaches production, its output could add a significant new commodity stream to the corridor's freight mix. The economics of connecting Manono to the Lobito Corridor are being studied as part of the Phase 3 expansion plan, though the 350-kilometer distance to the mainline makes a direct rail connection a medium- to long-term prospect.

Aggregate Freight Potential

These freight projections include not only refined metal output but also concentrates, process consumables (sulfuric acid, reagents, fuel), mining equipment, and general cargo that would shift from road to rail as the railway becomes operational. The total addressable freight market along the DRC segment is estimated at 4 to 6 million tonnes annually when return freight (imports for the mining industry and consumer goods for Katanga's growing urban population) is included.

The Luau-Dilolo Border Connection

The border crossing between Luau in Angola and Dilolo in the DRC is where the Angolan and DRC segments of the Lobito Corridor must physically connect. This junction is among the most critical bottlenecks in the entire project, and its resolution requires both new infrastructure construction and the harmonization of regulatory frameworks between two sovereign nations.

Infrastructure Gap

The original Benguela Railway terminated at Dilolo on the DRC side of the border, where it connected to the Chemin de fer du Katanga for onward movement to Katanga's mines. This border crossing functioned as a busy interchange point throughout the railway's golden era in the mid-20th century. However, the decades of civil war in Angola and institutional collapse in the DRC severed this connection completely. The physical infrastructure at the border — track, yard facilities, customs buildings, loading areas — was either destroyed or fell into complete disrepair. Reconnecting the two railways requires not merely track rehabilitation but essentially new construction of the border interchange facilities, including new rail yards on both sides of the border, customs and freight inspection facilities, gauge-compatible interchange infrastructure (both railways use Cape gauge, simplifying this aspect), security installations, and digital freight tracking and border clearance systems.

Regulatory Harmonization

Beyond physical infrastructure, the Luau-Dilolo crossing must overcome the regulatory and institutional barriers that have historically strangled cross-border trade in Central Africa. The Lobito Corridor Trade and Transit Facilitation Agreement (LCTTFA), signed by Angola, the DRC, and Zambia, provides the legal framework for harmonized customs procedures, mutual recognition of freight documentation, coordinated border management, and simplified transit regimes for mineral cargo. Implementing this agreement at the operational level requires training of customs officials, installation of compatible IT systems, agreement on working hours and service standards, and mechanisms for resolving disputes that will inevitably arise when cargo crosses between two different operational regimes.

The target is to reduce border crossing times from the current days-long process (when cross-border rail freight operates at all) to under 12 hours, with a longer-term goal of under 6 hours as systems mature and trust builds between the Angolan and Congolese border agencies. Achieving these targets would be transformative: the Luau-Dilolo crossing has the potential to become a model for efficient cross-border rail freight operations in Africa, or to become a permanent chokepoint that constrains corridor throughput regardless of how much is invested in railway rehabilitation on either side.

Construction Challenges

Rehabilitating the DRC segment presents a set of construction and operational challenges that are qualitatively different from those on the Angolan segment, where the LAR consortium benefits from a clearer concession framework, more accessible terrain along much of the route, and stronger institutional support from the Angolan government.

Logistics of Remote Construction

Large sections of the Dilolo-Kolwezi sub-segment pass through remote areas with minimal road access, limited power supply, no telecommunications infrastructure, and no construction support services. Mobilizing heavy construction equipment, rail, ballast, sleepers, and bridge materials to these locations requires establishing temporary construction logistics chains that are themselves major undertakings. In many cases, the only practical way to deliver materials to remote work sites is by using the very railway being rehabilitated, creating a circular dependency that complicates construction sequencing.

Security Considerations

The security environment in southern DRC, while considerably more stable than the conflict zones of eastern Congo, presents risks that construction planners must address. Artisanal mining activity along and near the railway right-of-way creates potential for conflict between formal construction operations and informal economic activities that have filled the vacuum left by the railway's decline. Theft of construction materials, particularly copper cable, rail fittings, and fuel, is a persistent problem that has plagued previous infrastructure rehabilitation efforts in Katanga. Armed groups are not a significant direct threat in the immediate corridor zone, but the broader security environment in the DRC remains volatile, and political instability at the national level could disrupt financing flows, regulatory approvals, or the SNCC partnership framework at short notice.

The Congolese mining police and the national army (FARDC) maintain a presence in the Katanga mining belt, and corridor security arrangements must navigate the complex relationships between state security forces, private mining security, and community expectations. The intersection of security forces and mining operations in southern DRC has been documented as a source of human rights concerns, and corridor developers must ensure that security arrangements for railway construction and operations do not exacerbate these issues.

Environmental and Social Factors

The railway route passes through areas of ecological sensitivity, including wetland systems, wildlife corridors, and forests that serve as carbon sinks. Environmental impact assessments are required under both DRC law and the environmental and social standards of international financiers such as the African Development Bank and the DFC. These assessments must address noise and vibration impacts on communities adjacent to the railway, water management during construction (particularly bridge works and drainage rehabilitation), dust and particulate emissions from ballast operations, management of construction waste and potential soil contamination, and biodiversity impacts along the right-of-way.

Social considerations are equally significant. The railway right-of-way has, in many areas, been encroached upon by informal settlements, agricultural plots, and artisanal mining operations during the decades when the railway was non-functional. Resettlement and compensation for affected communities is required under international standards but is politically sensitive and administratively complex in the DRC context, where land rights are often contested and institutional capacity for managing resettlement is limited.

Funding Sources

Financing the DRC segment's rehabilitation draws on a combination of multilateral development bank lending, bilateral development finance, private-sector investment by the LAR consortium, and anticipated contributions from the DRC government and mining companies.

Funding Structure

Financing Caveat

Earlier public commentary has named multiple possible funders for the DRC rail segment. For decision-grade use, this page now treats only institution-published commitments as verified. The DFC letter of interest is the clearest current official signal, but it remains subject to full review and does not by itself confirm financial close, concession award, or construction start.

Mining Company Take-or-Pay Arrangements

A critical element of the DRC segment's financial viability is the negotiation of take-or-pay freight contracts with the major mining companies along the route. Under these arrangements, miners commit to shipping a minimum volume of freight by rail over a defined period, providing the revenue certainty that lenders require to underwrite rehabilitation financing. The negotiation of these contracts is ongoing and complex, as miners must weigh the potential cost savings of rail transport against the execution risk of a railway rehabilitation programme in the DRC. Companies like Ivanhoe Mines, Glencore, and CMOC have expressed interest in rail access but have been cautious about making binding commitments until the rehabilitation programme demonstrates tangible progress.

Timeline & Outlook

The DRC segment's development timeline is the most uncertain of the three country segments that comprise the Lobito Corridor. While the Angolan segment benefits from an established concession structure and active construction under the LAR consortium, and the Zambia extension is still in the feasibility and design phase, the DRC segment occupies an uncomfortable middle ground: committed to rehabilitation but dependent on institutional partnerships and financing arrangements that remain partially unresolved.

Target Milestones

Risk Factors

Several risk factors could delay the DRC segment's rehabilitation beyond the target dates. Political instability in Kinshasa or at the provincial level could disrupt the SNCC partnership or freeze regulatory approvals. Changes in mineral commodity prices could undermine the economic case for rail transport, making it harder to secure take-or-pay commitments from miners. Cobalt price volatility, which has already affected investment decisions in the DRC mining sector, is a particular concern. Financing delays remain possible while prospective lenders complete review, impose conditions, or wait for DRC-side institutional prerequisites. Construction cost overruns, which are common in large infrastructure projects in challenging environments, could stretch available financing and force prioritization of some rehabilitation works over others.

Security deterioration in eastern DRC, while geographically distant from the Katanga corridor zone, could spill over through displacement, political distraction, or diversion of government resources. The DRC's broader governance challenges — including concerns about corruption, regulatory unpredictability, and the enforcement of contracts — create an operating environment where institutional risks are at least as significant as engineering and construction risks.

Strategic Significance

Despite these challenges, the strategic case for the DRC segment remains compelling. The Katanga mining province produces more than 70 percent of the world's cobalt and is rapidly expanding its copper output at a time when both minerals are essential to the global energy transition. The mines along the DRC segment will collectively produce millions of tonnes of metal annually through the 2030s and beyond, and that metal must reach global markets. Every tonne currently travels by truck to Lubumbashi, then south through Zambia and on to distant Indian Ocean ports. The Lobito Corridor offers a fundamentally shorter, cheaper, and Western-aligned alternative — but only if the DRC segment can be made to work.

The DRC segment is where the Lobito Corridor's ambitions will be tested most severely. It is where geopolitical aspiration meets ground-level reality, where billions in committed capital confronts decades of institutional decay, and where the world's appetite for critical minerals intersects with one of Africa's most challenging governance environments. Success on this segment would validate the entire Western strategy for building alternative mineral supply chains. Failure would leave the world's richest mineral province dependent on the same congested, expensive, and predominantly Chinese-connected logistics networks that the Lobito Corridor was designed to replace. The stakes, for the miners, for the DRC, and for the global energy transition, could hardly be higher.
