70000 series

Overview

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

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
