The Class C60 (C60形) is a 4-6-4 wheel arrangement steam locomotive type born from the rebuilding of 47 surplus Class C59 class 4-6-2 Pacific locomotives between 1953 and 1961 at the JNR Hamamatsu and Kōriyama factories. 39 locos were rebuilt from pre-war C59s, while 8 were rebuilt from post-war variants and renumbered C60 101 to 108. (See table below) With the spread of electrification, lower axle loads and greater versatility had become more important requirements than sheer pulling power, and so an additional trailing axle was included to reduce the heavy axle load of the C59 and allow more widespread use.

The class was most active on local and express passenger services in the Tohoku and Kyushu regions, and locos were to be seen operating in multiple (double- and even triple-headers) with Class C61s and Class D51s on both passenger and freight workings north of Morioka on the Tōhoku Main Line.

The class survived until 1971. Only one C60 is preserved: C60 1 in a park in Sendai.^[1]
