The Pureha-class (プレハ) locomotives were a group of steam tank locomotives with 2-6-2wheel 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]
The プレハ (Pureha) class was the eighth and final class of 2-6-2 locomotives procured by Sentetsu.[3] They were designed by Sentetsu as the most advanced locomotives in Korea at the time of their introduction, and the first twelve were built in 1932 by the Gyeongsong Works. A further 26 were built in 1939 by Hitachi and Kisha Seizō and assembled at Sentetsu's Busan shops.[4] Unlike previous Pure class locomotives, the Pureha class had larger driving wheels, with a diameter of 1,520 mm (60 in), which increased their maximum speed to 90 km/h (56 mph). They were frequently used for express trains on the Gyeongin Line.[4]
Many Pureha class locomotives were used by the Korean National Railroad after Liberation, which designated them 푸러8 (Pureo8) class;[4] they were used by the KNR primarily for shunting duties, and on light local and suburban passenger services.[5]
Korean State Railway 부러파 (Purŏp'a) class/1800 series
The Sentetsu Purena class locomotives that remained in the North after the partition of Korea were operated by the Korean State Railway, designating them 부러파 (Purŏp'a) class, and later renumbering them into the 1800 series around the early 1970s. The total number and identities of the engines that went north is uncertain, but it is known プレハ38 had gone to the north, where it was in use around Hamheung in 1951, still carrying Sentetsu number plates and emblems. It is unknown whether the locomotive remained in the North after the Korean War, or if it was taken by UN forces during the withdrawal.[5]
