This picture taken on May 25, 2026 shows buildings lit by the late afternoon sun as a pedestrian walks along a footpath in the city centre of Astana. The railway network of Kazakhstan, the world's largest landlocked country, runs on Soviet-era broad gauge (1520mm) track and stretches more than 16,500 kilometres.
