The Class C62 is a type of 4-6-4 steam locomotive built by Japanese National Railways (JNR) in Japan. The C classification indicates three sets of driving wheels. The C62 was built with a 4-6-4 frame, upon which was mounted the boiler of the JNR Class D52 2-8-2 locomotives.
These were the largest and fastest steam passenger locomotives to run in Japan, and hauled the Tsubame (swallow) express on the Tōkaidō Main Line between Tokyo and Osaka. Only South Africa operated more powerful Cape gauge locomotives. Forty-nine C62s were built from 1948 to 1949. Five C62s hauled the Teine express in Hokkaido between Otaru and Hakodate after they were displaced by electrification of the Tōkaidō Main Line. Two locomotives were used to double-head trains on the 2.5% (1:40) grades between Otaru and Oshamambe where they were a popular tourist and railfan attraction until 1971.[1] The last examples in regular service were withdrawn in 1973.
A class C62 locomotive, C62 17, broke the speed record for a narrow-gauge steam locomotive on 15 December 1954 when it reached 129 km/h (80 mph) on the Tōkaidō Main Line. This locomotive was preserved in a park in Nagoya, and later moved to the SCMaglev and Railway Park in Nagoya.
