The 200 class was a 4-6-2 superheated tender locomotive built by ALCO's Rogers Works in the United States. Three locomotives were completed in 1912 (Meiji 45), and one more in 1913 (Taisho 2), for a total of four. The design was broadly based on the JGR 8900 class, Japan's first 4-6-2 locomotive type, although the boiler was slightly smaller. In addition, whereas the 8900 class used a domestically built four-axle tender, the 200 class had an ALCO-built three-axle tender with a single bogie. Both superheating and the 4-6-2 wheel arrangement were adopted in Taiwan for the first time on this class. The locomotives were used to haul express trains and were reclassified as the C92 class in the 1937 (Showa 12) classification revision. While the Japanese 8900 class was withdrawn before the war as domestically built steam locomotives became more prominent, the Taiwan locomotives continued in service after the war as the Taiwan Railway Administration CT240 class and remained in use until the early 1970s. No examples are preserved today.
