Service outside Japan

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.[2]

Preserved examples

As of 2014, 43 Class 9600 locomotives are preserved at various locations in Japan.[3]

Number 39685, built in 1920, has been preserved outdoors in Chuo-ku, Saitama since 1972, but was scheduled to be removed and cut up in September 2016 due to the prohibitive cost of restoration.[4]
