Project Profile: Addis Ababa–Djibouti Standard Gauge Railway (SGR)

The Addis Ababa–Djibouti Railway is a 752.7-kilometer, standard-gauge electrified main line establishing a critical economic corridor between Ethiopia’s capital and Djibouti’s Red Sea port. This profile details the technical specifications and strategic importance of the first modern electrified railway in the Horn of Africa, which replaced the obsolete metre-gauge line built in 1917. The project serves as a key artery for freight and passenger transport, underpinning regional economic integration.

Technical Specifications

The railway infrastructure was constructed to Chinese National Railway Class I standards. The entire line is double-tracked for 115 km between Sebeta and Adama and single-tracked for the remaining 637 km to the Port of Doraleh. The 1435mm standard gauge track supports a maximum axle load of 25 tonnes, facilitating heavy freight operations. The line is electrified using an overhead 25 kV AC, 50 Hz system, powered by a series of traction substations connected to Ethiopia’s national grid.

The rolling stock consists of electric locomotives derived from the HXD1C platform, manufactured by CRRC Zhuzhou, providing high haulage capacity for freight trains that can exceed 3,500 tonnes. The signaling system employs a modern European Train Control System (ETCS) Level 1 standard, ensuring safe operations at design speeds. The route traverses challenging terrain, requiring the construction of 61 bridges and 453 culverts to navigate significant altitude changes from 2,500 meters near Addis Ababa down to sea level.

Key Takeaways

• Economic Lifeline: The SGR is the primary transport corridor for Ethiopia, a landlocked nation of over 120 million people. It handles over 95% of the country’s trade, reducing transit time from three days by road to approximately 12-15 hours by rail.
• Technological Benchmark: As the first fully electrified cross-border railway in Africa, the project introduced modern standards in gauge, electrification, and signaling to the region, setting a precedent for future infrastructure development on the continent.
• Strategic Partnership Model: The project’s financing and construction, largely supported by the China Exim Bank and Chinese state-owned enterprises, exemplifies the framework of the Belt and Road Initiative (BRI) for large-scale infrastructure projects in Africa, including long-term operations and maintenance contracts with a focus on local capacity building.

Frequently Asked Questions (FAQ)

What is the primary purpose of the Addis Ababa–Djibouti Railway?

The primary purpose is to provide a high-capacity, reliable freight link connecting landlocked Ethiopia with global maritime trade routes via Djibouti’s Port of Doraleh. While it also serves passengers, its core economic function is the efficient movement of containerized goods, bulk cargo, and fuel, drastically reducing logistics costs and transit times.

Who operates the Ethiopia–Djibouti Railway?

The railway is operated by the Ethio-Djibouti Standard Gauge Railway Share Company (EDR). Initially, a consortium of the primary Chinese contractors (CREC and CCECC) managed operations for a six-year period to ensure knowledge transfer and develop local expertise. EDR has since taken over full operational responsibilities.
