This picture taken on May 27, 2026 shows an Astana Light Metro train (middle C) making a stop at the Astana-Nurly Zhol station during the evening hour in 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. Overnight sleeper train travel between major cities is a popular way to explore both the historic and modern sides of Kazakhstan, Central Asia's most developed economy.
