The Tobu 70000 series (東武70000系, Tōbu 70000-kei) is a Japanese DC electric multiple unit (EMU) commuter train type operated by the private railway operator Tobu Railway on Tobu Skytree Line and Tokyo Metro Hibiya Line inter-running services since 7 July 2017.

Variants[edit]

  • 70000 series (in service since 7 July 2017)
  • 70090 series (in service since 20 March 2020)

70000 series[edit]

Overview[edit]

The 70000 series trains are scheduled to replace the 20000 series EMUs used on Tobu Skytree Line and Tokyo Metro Hibiya Line inter-running services.[1] Due to the effective length of the new trains which have 20 m (65 ft 7 in) long cars instead of the 18 m (59 ft 1 in) long cars of the 20000 series, the trains were formed of seven cars instead of eight cars to cope with Hibiya Line platform lengths, resulting in about a 1% reduction in capacity. A unified door arrangement with four pairs per side instead of the mixture of three and five pairs per side on the 20000 series trains allows the installation of platform edge doors on the Tokyo Metro Hibiya Line once the older train fleets have been replaced.[1] The trains use permanent-magnet synchronous motors (PMSM), offering 25% energy savings compared to the motors used in earlier 20000 series trains.[2]

Formation[edit]

The 70000 series trains are formed as seven-car sets as shown below, with car 1 at the northern end.[3] Each car is motored, with only the outer axle on each bogie motored.[3]

History[edit]

The first set, 71701, on delivery in February 2017

Tobu Railway announced its plans to introduce a new fleet of trains with 20 m (65 ft 7 in) long cars and four sets of doors per side on each car in April 2014, jointly with Tokyo Metro.[4] Details of the new 70000 series trains on order were officially announced on 17 June 2015, together with details of the Tokyo Metro 13000 series to be introduced around the same time.[2] The entire fleet of new trains is scheduled to be delivered between fiscal 2016 and fiscal 2019,[2] with the first set delivered from Kinki Sharyo in February 2017.[5]

The first trains entered revenue service on 7 July 2017.[6]
