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 235–238 and intended for local freight trains, and had a lower profile than the previous Baldwin designs.[1] They were renumbered 661–664 in 1918, finally being designated テホシ (Tehoshi) class in the 1938 general renumbering, numbered テホシ1 through テホシ4.[1]
All four locomotives of the class went to the North after the partition, where they were designated 더우너 (Tŏunŏ) class by the Korean State Railway and numbered 더우너1 through 더우너4, but little is known of their service lives and subsequent fates.
