[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] 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.

[4] 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.
