Malaya Yuzhno-Uralskaya railway, railway line in Russia

The Malaya Yuzhno-Uralskaya railway is a 5.8 km narrow-gauge children's railway in Chelyabinsk, running through the Shershnyovsky (Gorodskoy) bor and Gagarin Park. It has five stations — Zvezdnaya, imeni Pavlika Morozova, Vodnaya, Lesnaya and Solnechnaya — plus the Zoopark platform. Trains are hauled by TU7A and TU10 diesel locomotives; a steam locomotive 157S-24 is used only on holidays.

Design work began in 1939 and construction on 12 May 1940; the opening planned for 2 August 1941 was cancelled when the rails and steam locomotives were requisitioned for the war. Building resumed in 1947, and the line opened on 31 July 1949 with a 700 m section from Pavlik Morozov station to passing loop No. 1, the first train driven by young railwayman Volodya Vyrin. The 1953 reconstruction brought TU2-012 "Cosmonaut" and the Vodyanaya station, and by 1961 the line reached 4 km with the opening of Pionerskaya.

The line is run by children: the staff is divided into five shifts, and each season contests are held for titles such as best conductor, driver, or signal operator. The first train in 1949 was driven by young railwayman Volodya Vyrin. Two passenger trains now run: the daily yellow-and-red Yunost and the weekend yellow-and-green Yuzhnouralets.

Trains run from May to September five days a week, with Monday and Tuesday off. The 5.8 km route links Zvyozdnaya and Solnechnaya through five stations and the Zoopark platform. Two trains serve the line: the daily four-car Yunost and the weekend three-car Yuzhnouralets.

A steam locomotive, 157S-24, returned to the line in December 2025 after a major overhaul and runs only on holidays. The regular fleet is diesel: TU7A-3356 and TU7A-3359, plus TU10-015, which came back from repair in Kaluga on 15 November 2019 after its hydraulic transmission failed on the climb to Solnechnaya.
