The Tehoshi-class (ãÂÂãÂÂã·) locomotives were a class of steam tender locomotives of the Chosen Government Railway (Sentetsu) with 4-6-0 wheel arrangement. 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".
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.
Following the brief excursion to ALCo for the Tehosa class, Sentetsu once again returned to Baldwin for the next order of 4-6-0s. This was a small lot of four locomotives built in 1913, initially numbered 235âÂÂ238 and intended for local freight trains, and had a lower profile than the previous Baldwin designs. They were renumbered 661âÂÂ664 in 1918, finally being designated ãÂÂãÂÂã· (Tehoshi) class in the 1938 general renumbering, numbered ãÂÂãÂÂã·1 through ãÂÂãÂÂã·4.
All four locomotives of the class went to the North after the partition, where they were designated ëÂÂì°ë (Tà Âunà Â) class by the Korean State Railway and numbered ëÂÂì°ëÂÂ1 through ëÂÂì°ëÂÂ4, but little is known of their service lives and subsequent fates.
