Career
Class О

The Russian steam locomotive class O (from Russian: Основной) was an early type of Russian steam locomotives. Between 1890 and 1928, 9129 locomotives were built; hence it was second most numerous locomotive class in Russia, after E class,[1] what was unique number also in the world's scale.

Variants

Basic variants were early Od and OD (Russian: Од, OД) with Joy valve gear and most numerous later OV (OВ) with Walschaerts valve gear. Some locomotives were built as two cylinder simple expansion and others as two cylinder compounds.[2]

Armoured locomotives

In World War I, the Russian civil war and the Eastern Front of World War II O-class locomotives were widely used as standard armoured locomotives in armoured trains.

Minecraft

The Class O locomotive was also included in the Rails of War Mod for Minecraft. It only comes with no armor, and a black paint-scheme(you can change it with dye), and is the biggest and fastest loco in the mod, with chuffing sounds, and a 5-chime steam whistle, and it goes well with the other engines: B-2023, an 0-6-0, and the Cherepanov loco.
