72 series

The 72 series (72系) trains were DC electric commuter trains operated by Japanese National Railways (JNR), and served as the basis for the 101 series. The 72 series included the main production batch of 490 vehicles as well as 667 former 63 series cars converted into 72 series between 1953 and 1955. The last remaining trains were withdrawn in 1985, although some cars which were converted into mail coaches and experimental vehicles continued to remain in service until 1996.
