The Pureshi-class (プレシ) locomotives were a group of steam tank locomotives with

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]

Description

The Pureshi class consisted of 46 Purei-class locomotives rebuilt by Sentetsu's Gyeongseong Works from 1925. Major modifications included increasing the size of the firebox to allow the use of lignite, which has a lower caloric value than anthracite coal. Boiler volume was increased, the heat transfer area was increased, the stoker was enlarged, and special attention was given to the prevention of sparks. The performance was found to be good, and eventually 46 Purei class locomotives were rebuilt to Pureshi standard. The redesign work also gave Sentetsu engineers important experience, which was later applied to the design of the Pashishi and Mikasa-class locomotives.^[3] After Sentetsu's general renumbering of 1938 they were numbered プレシ1 through プレシ46.

The original identities of the locomotives rebuilt is unknown.

Postwar

After the

Korean National Railroad in the South would be designated 푸러4 (Pureo4) class, those with the Korean State Railway

in the North would be designated 부러너 (Purŏnŏ) class.
