Tobu Railway Series 5000 emus -- a memorandum

Noda Line of Tobu Railway in Japan was once famous for its fleet of over 200 electric multiple unit (emu) railcars, all with nose-suspension drive mechanisms. However, that was towards the end of 1980s; Series 5070 fleet, which was expected to dominate the line for some time after the withdrawal of even older Series 3000, has now reduced to only 3 trainsets and is expected to disappear before late this year. Being in UK now and not having any plan of immediate visit to Japan, I am a bit saddened to think of the fact that I will never see them run on Noda Line again with my eyes.

Therefore, I dedicate this page to the history of Series 5000, its predecessor Series 7800, or Tobu Railway's infamous and singular fleet policy of "car body renewal", probably with a bit of criticisms.

    In 1953, Tobu introduces 7330, the first commuting cars newly built by private railways in Japan that came with 20-metre car body. The design, however, was with only minor modifications to Series 73.

  • Repeat orders of Series 78   (Tobu's Series 5000 memo)
    The repeat orders of Series 78 continues. However, by 1960, the fleet was already desperately old and obsolete.
