Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 27, p. 219. Works numbers were 25090, 25096-25097, 25113-25120, 25139, 25150-25152, 25161-25162, 25197-25198 in February 1905; 25246 in March.
Japan's occupation and colonization of Korea included rapid development of the peninsula's railway system. The model of course was that of Japan and once established, varied little. The large batch of Prairie tanks in this entry were virtual repeats of the 2 shown in Locobase 12495.
