Су
Su is a Soviet passenger steam locomotive displayed at the Railway Museum in Tashkent, Uzbekistan. Its broad Russian-gauge wheels and substantial boiler reflect the railway demands of the early Soviet period.
Designed in 1924, this locomotive became the Soviet Union’s first passenger steam locomotive developed within the country. Production continued until 1951, with 2,683 locomotives built for non-electrified railway lines. A larger firebox, longer smokebox, and additional heating tubes gave the design greater power. Its low axle load also allowed heavier passenger trains to use routes unable to support the heaviest locomotives. Diesel and electric traction gradually replaced the class during the 1960s, while preserved examples remained in museums and working collections.
The Tashkent exhibit is Su 250-94, a tangible survivor of decades of passenger travel across the Soviet railway network. Another preserved locomotive, Su 251-86, remains operational in Ukraine.
