[] by Ejii Nozawa data. Nozawa says that these were improved CK50s, from which they differed in having higher boiler pressure, higher adhesive weight, and a smaller boiler and firebox.
These were virtual duplicates of the JNR's C12 class and were operated on the island of Taiwan, then called Formosa and governed by the Japanese.
Data from Hiroshi Takagi, both from his website ([]) and personal communication August 2000.
Information from Ejii Nozawa's web site ([]) about the number and dates built.
[] by Ejii Nozawa data. After a trial run of two locomotives, which had very slightly different dimensions, Kisha Seiko delivered twelve more engines of this class between 1905 and 1912. These long-boilered tans were used on mountain sections, according to Nozawa.
