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.
