ADB lends Baku $302 million for metro signalling inside a $2.6 billion expansion

The Asian Development Bank approved a $302.38 million loan on 13 October to replace Baku Metro’s signalling with communications-based train control and to digitalise its operations. The project costs $515.07 million, with the Asian Infrastructure Investment Bank adding $79.98 million and the government $132.71 million, and sits inside a state programme the bank puts at $2.6 billion.

Baku Metro, operated by the state-owned Baku Metropolitan Closed Joint-Stock Company, runs 27 stations on about 41 kilometres of track and recorded about 220.4 million passenger boardings in 2025, the bank’s release says. The government’s expansion programme adds about 20 kilometres of new tunnels with 9 stations, 2 depots and 300 more metro cars, together with the modernisation of operating systems, to widen coverage and ease road congestion in greater Baku.

The loan replaces the existing signalling with communications-based train control and upgrades the operations control centre, which the bank expects to allow more frequent trains at peak hours and fewer operating incidents. Beyond signalling, it pays for integrated digital systems for corporate functions, asset management, cybersecurity, passenger information and crowd management, with upgraded data centres and secure networks.

“Advanced signaling technology and integrated digital operations systems will make existing services safer and more reliable, while laying the foundation for the efficient operation of Baku’s rapidly expanding metro network,” said Sunniya Durrani-Jamal, the bank’s country director for Azerbaijan.

The project also funds technical training and workforce development at the operator, with recruitment, training, certification and career measures for women in technical and digital roles.
