[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] The テホイ (Tehoi) class was a class of six 4-6-0 Vauclain compound locomotives for mainline use built by the Baldwin Locomotive Works of the United States in 1906, originally for the Gyeongbu Railway, and later operated by the Chosen Government Railway.

[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 two-cylinder Vauclain compounds and the other six were single-cylinder locomotives, which were delivered in knockdown form and assembled at the railway's shops in Busan.

[3] The exact dispersal of the six Tehoi-class locomotives after the partition of Korea in 1945 and the division of Sentetsu assets in 1947 is uncertain, but at least one went to the South, where the Korean National Railroad designated them 터우1 (Teou1) class.
