The World Bank has committed $500 million to overhaul Nairobi's aging commuter rail network, with total project costs estimated at $1.7 billion. The initiative, currently in concept review, will upgrade stations, purchase new rail carriages, and modernize infrastructure across Kenya's capital. The financing represents a major investment in East Africa's largest urban transportation system.

Beyond physical upgrades, the project aims to transform Nairobi's mobility landscape by establishing a modern urban rail system and reforming institutional frameworks for urban transport. The Washington-based lender will fund feasibility studies and preliminary design work, including electrification readiness assessments. Technical assistance for carbon financing opportunities will also be provided.

The initiative extends beyond Nairobi, with future expansion planned for secondary cities including Mombasa, Kisumu, Nakuru, and Eldoret. Policy support includes establishing urban mobility funding mechanisms and exploring securitization of the Railway Development Levy. This comprehensive approach signals a significant shift toward integrated urban planning and sustainable transportation in Kenya.
