JNR Class 9600


The Class 9600 are a type of "Consolidation" steam locomotives built by Japanese Government Railways 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, and were extensively used for freight service throughout Japan.
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 until the 2nd of March 1976, when all steam-hauled service on JNR's network has been phased out.

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 ; 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.

Preserved examples

, 43 Class 9600 locomotives are preserved at various locations in Japan. There had originally been 46 preserved, but over time 3 were scrapped due to neglect and high maintenance costs.
Number 39685, built in 1920, was preserved outdoors in Chuo-ku, Saitama since 1972, but was removed and scrapped in September 2016 due to the prohibitive cost of restoration.
Number 29657, built in 1919, had been preserved and used for the Morimon Onsen SL Land hotel in the Niigata Prefecture of Uonuma City in 1979. In 1998, the SL Hotel business was discontinued and the engine and consist were left as an outdoor public display. In 2015, it was abandoned after the Morimon Onsen Seiunkan closed in March of that year. One of the two passenger carriages was removed sometime before or during 2014. In 2022, 29657 and the last coach were scrapped on-site years later.
On April 22nd, 2024 number 19633, built in 1917, which was previously on display outdoors near the Wakamatsu Station in the Fukuoka Prefecture, Kitakyushu City since 1989, was scrapped after being exposed to the elements and neglected for many years with little cosmetic maintenance.
