 The Russian steam locomotive class Izhitsa (Ѵ) was a steam locomotive produced in Russia and the Soviet Union between 1908 and 1918, and between 1927 and 1931. The Russian letter Ѵ can be transliterated as ü. On Russian and Soviet railways, these were the most powerful steam locomotives of type 0-8-0. They were designed by E. E. Noltein and had a 16-ton axle load.[1] 
  Similar class
 The Russian locomotive class Y (Ы) was similar but had a 15-ton axle load. In the period 1909–1916, 350 class Y (Ы) locomotives were built.
