The Class 9600 (9600形) are a type of 2-8-0 "Consolidation" steam locomotives built by Japanese Government Railways (JGR, after-day Japanese National Railways (JNR)) from 1913 to 1925. They were the first locomotive class to be mass-produced by Japanese manufacturers. The Class 9600 were popularly known as Kyuroku (nine-six), and were extensively used for freight service throughout Japan.[1]
They were numbered 9600-9699, 19600-19699, 29600-29699, 39600-39699, 49600-49699, 59600-59699, 69600-69699 and 79600-79669. All 770 remained in service[citation needed] before they were gradually withdrawn until the 2nd of March 1976, when all steam-hauled service on JNR's network has been phased out.[2]

Taiwan Railways Administration DT580

From 1923 to 1939, Kawasaki, Kisha Seizō, Nippon Sharyō, and Hitachi built 39 9600s for the Government General of Taiwan. The Taiwan Government Railway classified them 800 class before 1937, and they were classified D98 after 1937. After World War II, they were taken over by Taiwan Railways Administration, and they were classified DT580. One engine, DT619, is being rebuilt by combining parts of scrapped locomotives after the war.

China Railway class KD5/KD55

To alleviate a severe motive power shortage on the Central China Railway, JNR locomotives were converted from Japanese narrow gauge to standard gauge and shipped to China. 251 Class 9600 locomotives were sent for use on both the Central China Railway and the North China Transportation Company (NCTC class ソリコ (Soriko)); after the Pacific War, these became China Railway class KD5. Others were rebuilt to metre gauge for operation on Yunnan's Kunming–Hekou Railway and its branches; these eventually became China Railway class KD55.[3] This class retired in 1980s.
