of Kenya, jointly, publicly committed to extend the Standard Gauge Railway (SGR) to Kampala via Malaba. The Kenyan government in 2020 reached a deal with AfriStar to take over operations and maintenance by May 2022. Kenya received its first SGR rolling stock in May 2017: 18 locomotives and 60 double-stack container cars. In early February 2024, Kenya received a second batch of 50 cars, with an additional 250 cars to be delivered within the month. 20 of the expected wagons will have power plugins to enable the movement of refrigerated containers, while another 20 will be passenger coaches.
