[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.
[1] 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).
Six of these were six were single-cylinder locomotives and the other six were two-cylinder Vauclain compounds which were delivered in knockdown form and assembled at the railway's shops in Busan.
[1] The exact dispersal of the twenty-one Tehosa-class locomotives after the partition of Korea in 1945 and the division of Sentetsu assets in 1947 is uncertain, but at least nine went to the South, where the Korean National Railroad designated them 터우2 (Teou2) class.
[5] Those that went to the North were designated 더우두 (Tŏudu) class by the Korean State Railway, but little is known of their service lives and subsequent fates.
