Data from Baldwin Locomotive Works Specification for Engines, 1890, as digitized by the DeGolyer Library of Southern Methodist University Vol 27, p. 108. Works numbers were 24160-24161 in April 1904;24179, 24185-24186, 24191-24194, 24206-24208 in May
This class, bought by Frazar & Company, repeated the design of 1901 Seoul-Chemulpo locomotives (Locobase 12495). The latter 7 were later assigned to the Japanese-controlled Seoul Government Military Railway.
