Sentetsu 4-Wheel class locomotives

The 4-Wheel class locomotives were a class of steam tank locomotives with 0-4-0 wheel arrangement introduced by the Gyeongbu Railway Company in April 1906 for use on the Gyeongui Line.
The Hohenzollern [Locomotive Works] of Germany in 1899 built a number of 0-4-0 tank locomotives for the Imperial [Japanese Army|Japanese military] in 1899. The Gyeongbu Railway Company obtained two of these in April 1906 for use on the Gyeongui Line opened that year. The Chosen [Government Railway] was founded on 1 July 1906 with the acquisition of the Gyeongbu Railway, and used the two locomotives on the Gyeongui Line for shunting and short-haul trains.
They were likely retired prior to 1938, as they were not listed in Sentetsu's general renumbering of that year.
