The Purero-class (プレロ) locomotives were a group of steam tank locomotives with 2-6-2 wheel arrangement of used by the Chosen Government Railway (Sentetsu) in Korea. The "Pure" name came from the American naming system for steam locomotives, under which locomotives with 2-6-2 wheel arrangement were called "Prairie".[1]
In all, Sentetsu owned 227 locomotives of all Pure classes, whilst privately owned railways owned another 52; of these 279 locomotives, 169 went to the Korean National Railroad in South Korea and 110 to the Korean State Railway in North Korea.[2]
Orenstein & Koppel of Germany built two superheated 2-6-2 tank locomotives in 1911 which were operated by the privately owned Domun Railway after 1920. Both were taken over by Sentetsu after the nationalisation of the Domun Railway in 1929; after the general renumbering of 1938 they were designated プレロ (Purero) class and numbered プレロ1 and プレロ2.[3]
After the Liberation and partition of Korea, both ended up in North Korea after Liberation, and were operated by the Korean State Railway[3] designated 부러유 (Purŏyu) class.
