Taiwan Railway 2-8-0 Locomotives in Formosa
Class Details by Steve Llanso of Sweat House Media
Class DT560 (Locobase 3868)
Data from Hiroshi Takagi, both from his website ([
]) and personal communication August 2000.
Information from Ejii Nozawa's web site ([]) says this batch of engines, identical to the Japanese-built 9600s, was delivered from Alco in 1919-1920.
Class DT580 (Locobase 3869)
Data from Hiroshi Takagi, both from his website ([]) and personal communication August 2000. See also "JGR Class 9600", Steam Locomotives, Locomotive Wiki at [], last accessed 20 January 2024. (See Scott Simon, "Formosa's First Nations and the Japanese: from colonial rule to postcolonial resistance", Asia-Pacific Journal, Volume 4, Issue 1 (4 January 2006), archived as [] , last accessed 20 January 2024.
Information from Ejii Nozawa's web site ([]) says these were identical to the JNR's 9600s (Locobase 3816) and also were built by Hitatchi, Kawasaki, KSK, and Mitsubishi.
When Japan took over Formosa (fka Taiwan) in 1895, the new rulers adopted a program of modernizaton that included modernizing transportation. Much of Formosa's rolling stock produced during the fifty years of occupation featured Japanese designs produced by Japanese builders.
Thus these DT580 Consolidations repeated the successful JGR Class 9600 descirbed in Locobase 3816.
