Taiwan Railway 4-6-2 Locomotives in Formosa
Class Details by Steve Llanso of Sweat House Media
Class CT270 (Locobase 3867)
See data from Hiroshi Takagi, both from his website ([
]) and personal communication August 2000. These were duplicates of the JNR's C57 Pacifics.
Information from Ejii Nozawa's web site ([]) notes that these 14 came from Hitachi and Kawasaki from 1942 to 1953.
