The Tobu 20000 series (東武20000系, Tōbu 20000-kei) is a commuter electric multiple unit (EMU) train type operated by the private railway operator Tobu Railway in Japan since 1988.[2]

The 20000 series fleet is scheduled to be replaced by new Tobu 70000 series EMUs with 20 m cars, but as of 1 April 2016, all 24 sets (192 vehicles) built were still in service.[3]

  • 20000 series: 13 x 8-car sets introduced from March 1988
  • 20050 series: 8 x 8-car sets introduced from December 1992 with 5-door cars
  • 20070 series: 3 x 8-car sets introduced from March 1997

20000 series[edit]

13 eight-car sets (21801 to 21813) were built to replace the ageing 2000 series trains on inter-running services between the Tobu Skytree Line and the Tokyo Metro Hibiya Line in Tokyo, entering service on 25 March 1988. The body design uses a new lightweight corrugated stainless steel construction.[2] These trains use the same AFE chopper control as the earlier Tobu 9000 series trains, bolsterless bogies.[4]

Total number of vehicles built: 104[2]

Trains are formed as follows, with six motored ("M") cars and two non-powered driving trailer ("Tc") cars.[5]
