The C62 4-6-4 Steam locomotives were the largest and fastest steam passenger locomotives to run in Japan, and hauled the "Tsubame" express on the Tokaido Main Line between Tokyo and Osaka. Forty nine were built from 1948 to 1949. The last examples in regular service were withdrawn in 1973. They have since been replaced by the more modern bullet train designs, but for their time they were a common sight in passenger service.
