Tanzania has signed a $1.2 billion commercial financing facility for a 411-kilometre electrified railway linking Tabora and Kigoma in the country's west. The African Development Bank (AfDB) announced the signed deal on 4 November 2026, and it was reported widely on 10 and 11 November.

The line, designated Lot 6 of Tanzania's Standard Gauge Railway (SGR) programme, will connect the Indian Ocean port of Dar es Salaam with Lake Tanganyika and the border with the Democratic Republic of Congo, creating a new transport corridor for domestic and cross-border trade.

How the $1.2 billion financing works

The AfDB acted as Initial Mandated Lead Arranger for the facility and structured a Partial Credit Guarantee of up to $800 million, its largest guarantee of this kind to date. The guarantee covers the principal of the protected tranche plus two years of interest.

The bank mobilised a nine-bank syndicate for the commercial facility, co-arranged by Deutsche Bank and Societe Generale. The other lenders are HSBC, Commerzbank, Nedbank, Stanbic Bank Tanzania, First Abu Dhabi Bank, FirstBank UK and Bank of Africa UK.

Of the $1.2 billion, $720 million is guaranteed lending and $480 million is lending based on direct sovereign risk. The AfDB said the deal illustrates how its New African Financial Architecture for Development, known as Nafad and launched in May 2026, can mobilise private capital through risk-sharing with development finance institutions.

Part of a wider $2.3 billion package

The signed $1.2 billion facility forms part of a wider $2.3 billion financing package for the Tabora-Kigoma section, which also includes an export credit agency-backed tranche and a further tranche to be mobilised with a co-guarantor. Tanzania had mandated the AfDB to structure and mobilise up to $3.2 billion for its regional railway development through the SGR project.

The financing is intended to support construction of the electrified line, which is designed to replace the limitations of Tanzania's older metre-gauge railway with a modern network offering greater capacity and operational efficiency. The announcement does not establish a completion date for the section.

Why the railway matters

The Tabora-Kigoma line is a strategic link in Tanzania's national railway network. It is expected to improve the movement of goods between Dar es Salaam and Lake Tanganyika, serving western Tanzania's agricultural and mining regions and giving landlocked neighbours a faster route to the Indian Ocean.

For Tanzania, the deal is also a test of a financing model that blends commercial bank lending with development-bank guarantees and private insurance. Lloyd's syndicates are among the insurers sharing part of the exposure, and the AfDB said the structure was designed to meet the differing risk appetites of different classes of investor.

Earlier sections of the SGR between Dar es Salaam and Dodoma have already entered passenger service, and the Tabora-Kigoma section would extend the network deep into the west of the country once construction is complete.
