The Tehosa-class (テホサ) locomotives were a class of
Chosen Government Railway (Sentetsu) with 4-6-0 wheel arrangement.[1] The "Teho" name came from the American naming system for steam locomotives, under which locomotives with 4-6-0 wheel arrangement were called "Ten Wheeler".[2]
After the
Liberation of Korea, of the 178 surviving locomotives of all Teho classes - including six previously owned by private railway companies - 106 went to the Korean National Railroad in the South, and 72 to the Korean State Railway in the North.[3]
Description
Whilst the first two classes of 4-6-0 locomotives in Korea, the
American manufacturer for the third class - ALCo's Brooks Works[4] built nine such locomotives for Sentetsu in 1911.[1] Intended for long-range mixed trains, they were initially numbered 222–230, and subsequently were renumbered 651–659 in 1918. After being rebuilt with superheaters in the 1930s, they were redesignated テホサ (Tehosa) class and numbered テホサ1 through テホサ9 in the 1938 general renumbering.[4] Like all Teho-type locomotives operated by Sentetsu, they had driving wheels of 1,680 mm (66 in) and a top speed of 95 km/h (59 mph),[1] and many were assigned to the Manpo Line in the northern part of the country.[1] One final unit, テホサ10, was built by Gyeongseong Works in 1938.[4]
Postwar
Korean National Railroad 터우3 (Teou3) class
The exact dispersal of the ten Tehosa-class locomotives after the
partition of Korea in 1945 and the division of Sentetsu assets in 1947 is uncertain, but at least two went to the South, where the Korean National Railroad designated them 터우3 (Teou3) class [1] and were used primarily on branchline trains.[4]
Korean State Railway 더우서 (Tŏusŏ) class
Having been assigned primarily to the Manpo Line,[1] most of the class went to the North after the partition, where they were designated 더우서 (Tŏusŏ) class by the Korean State Railway, but little is known of their service lives and subsequent fates.
