In a major update for Tanzania’s southern logistics network, the government officially announced the completion of the feasibility study and preliminary engineering designs for the 1,000-kilometer Mtwara to Mbamba Bay Standard Gauge Railway (SGR). The massive infrastructure project, estimated to require a total investment of approximately $5.6 billion, is designed as a heavy mineral and cross-border transport corridor starting at the Mtwara Port on the Indian Ocean and terminating at Mbamba Bay on the shores of Lake Nyasa. The blueprint features a main track with a designed passenger speed of 160 km/h and a freight speed of 120 km/h, alongside critical branch lines (spurs) extending directly into the mineral-rich zones of Liganga and Mchuchuma to unlock massive coal and iron ore deposits. Also, this particular project is part of Tanzania’s effort to develop a standard gauge railway infrastructure which is set to be linked to the neighboring East African countries.

Because this extensive project is not funded under the government’s direct capital investment list, the Ministry of Transport is actively mobilizing international financial partners and promoting a phased Public-Private Partnership (PPP) framework to secure the necessary private capital. Recognizing its broader macroeconomic potential, the East African Community (EAC) has integrated the network into the East Africa Railway Master Plan. Once finalized, the railway will operate as a vital land-sea intermodal link, connecting landlocked neighboring nations like Malawi, Mozambique, and Zambia to international maritime trade routes while accelerating the industrialization of southern Tanzania.

The Republic of Tanzania has initiated efforts of seeking $5.6 billion for the construction of Mtwara-Mbamba Bay Railway that shall connect the Indian Ocean to Lake Nyasa and traverse the regions that are rich in iron-ore and graphite minerals. In addition the country has also started the search of public-private partnerships for the railway. This information was revealed by the Tanzania Railways Corporation (TRC). The agency made a pitch to the potential investors and financers of the project at the Africa Investment Forum that was held in Marrakech, Morocco. At the beginning of this month, an interest of $2.2 billion in the project was also secured by the country.

This Mtwara-Mbamba Bay Railway that spurs to the neighboring countries of Mozambique, Malawi, and also Zambia was first proposed to be constructed about twenty years ago. This railway will be mainly utilized for transporting coal and iron ore from the mine fields situated at Liganga and Mchuchuma. The railway will also provide services to companies like Dangote Cement Plc and Tancoal Energy Ltd.

Mtwara-Mbamba Bay Railway Length

The Mtwara-Mbamba Bay Railway shall cover a distance of 1,000- kilometers (621 miles) . Currently, the Republic of Tanzania has kicked off the efforts of expanding its general railway network in order to speed up industrialization and also promote trading activities by capturing cargo for the countries that surround it. The country is also building a railway line other than this one that runs a distance of 1,219 kilometers. This other railway shall connect the Port of Dar es Salaam and Mwanza city by Lake Victoria. The railway line will also branch to the western part of Burundi, DRC, and also Rwanda.

According to the Turkish contractor Yapi Merkezi Insaat VE Sanayi that was given the contract of building a total of four phases of the railway, they are currently restructuring loans worth $1 billion that was brought about by its cash flow being hit by a row over payment. China Civil Engineering Construction Corporation and China Railway Construction Ltd are also developing a part of the other railway line.

Project Factsheet

Project Status: Feasibility studies and preliminary engineering designs completed.

Total Mainline Track Length: 1,000 km.

Key Intended Route: Mtwara Port (East)- Songea-Mbamba Bay (West).

Strategic Branches (Spurs): Direct dedicated rail links branching into the mineral-rich zones of Liganga (iron ore) and Mchuchuma (coal).

Executing Agency: Tanzania Railways Corporation (TRC).

Technical Specifications

• Track Gauge: 1,435 mm (Standard International Gauge)
• Designed Passenger Speed: 160 km/h
• Designed Freight Speed: 120 km/h
• Initial Traction Profile: Diesel traction (with full structural provision for future electrification)
• Primary Rolling Asset Focus: Heavy mineral freight (coal, iron ore, graphite) & intermodal cargo containers

Financing and Project Delivery Framework

• Estimated Capital Requirement: USD 5.6 Billion.
• Procurement Model: Phased Public-Private Partnership (PPP) framework. Because this corridor falls outside the state’s direct capital investment list, the Ministry of Transport is seeking global private equity, syndicated bank arrangements, and mining investor pairings.
• Early Institutional Traction: Initial investor outreach has already generated up to USD 2.2 Billion in tentative financial interest from various multinational institutions.

Strategic Regional Impact

• Unlocking the Southern Resource Corridor: The railway provides the vital heavy logistics backbone required to finally monetize the extensive coal deposits at Mchuchuma and iron ore reserves at Liganga, feeding industrial manufacturing and potential steel production.
• The Land-Sea Multimodal Corridor: By ending at the Mbamba Bay port on Lake Nyasa, it establishes an efficient intermodal shortcut for cross-border transit. This gives landlocked parts of Malawi, Zambia, and Northern Mozambique a reliable, cost-effective trade gateway directly to Mtwara Port for international shipping.

Project Team

Project Proponent & Institutional Oversight (Client)

• The Government of the United Republic of Tanzania (GoT): High-level policy, funding mobilization, and cross-border multi-nation alignment are driven by the Ministry of Transport and the Ministry of Finance.
• Tanzania Railways Corporation (TRC): The primary state implementing agency managing the strategic layout, feasibility studies, and public-private partner procurement.

Engineering Consultancy and Design

• UNITEC Civil Consultants Ltd (Tanzania): The prominent local engineering consultancy firm responsible for executing the comprehensive feasibility study and preliminary engineering designs for the full 1,000 km network layout, including the critical mining spurs.

Resource and Industrial Integration Partners

• Tanzania-China International Mineral Resources Ltd (TCIMRL): The corporate joint venture structure historically earmarked to align heavy mining infrastructure and power generation operations at the Mchuchuma coal and Liganga iron ore hubs, directly linking raw material extraction to the corridor’s freight logistics.

Regional and Financial Stakeholders

• Southern African Development Community (SADC): A primary regional integration backer that provided early-stage grant funding (approx. USD 6 million) through the Development Fund to accelerate detailed design and alignment strategies under the Mtwara Development Corridor framework.
• East African Community (EAC) & Program for Infrastructure Development in Africa (PIDA): Oversight bodies tracking the corridor’s compliance with the wider East Africa Railway Master Plan to guarantee intermodal connection safety with landlocked trade partners like Malawi and Zambia.
