They were numbered D62 1-D62 20 (formerly D52 368/D52 448/D52 401/D52 450/D52 449/D52 42/D52 344/D52 336/D52 94/D52 132/D52 337/D52 397/D52 211/D52 334/D52 377/D52 338/D52 343/D52 360/D52 339/D52 462) were renumbered D62 1-D62 20 between 1950 and 1951 rebuilt by the JNR Hamamatsu Works in 1950 and 1951 they were retired in 1966 .
