The C classification denotes three sets of drive wheels . The C51 introduced 1.75 meters (5 ft 9 in ) driving wheels to Japan. The C51 series increased the average speed on the Tōkaidō main line from 47.3 km / h to 55.3 km / h. In 1930, a C51 towed the first tsubame (swallow) express, reducing travel time between Tokyo and Kobe to nine hours.
