Kenya’s rail network is undergoing significant transformation with the Standard Gauge Railway (SGR) operating alongside the historic Meter Gauge Railway (MGR) system. The network plays a crucial role in the East African transport corridor, connecting the Port of Mombasa to inland countries including Uganda, Rwanda, and South Sudan. The modernization program represents one of Africa’s largest railway infrastructure projects, with Chinese technical standards adopted for the SGR while maintaining legacy MGR operations.
The system faces unique challenges including varied terrain from coastal to highland regions, seasonal weather patterns affecting operations, and the need to integrate two different gauge systems. The development strategy focuses on creating an efficient multi-modal transport network while improving urban mobility, particularly in Nairobi and Mombasa.
