The Seibu 40000 series (西武40000系?) is a commuter electric multiple unit (EMU) train type on order by the private railway operator Seibu Railway in Japan for entry into service from spring 2017. A total of eight ten-car trainsets are to be built by Kawasaki Heavy Industries in Kobe from 2016, with the first trains entering service in spring 2017.
The new 40000 series trains will be built by Kawasaki Heavy Industries in Kobe from January 2016, with deliveries from fiscal 2016 to 2019. This is the first time that trains for Seibu Railway have been built by this manufacturer.
The new trains are designed as an evolution of the 30000 series "Smile Train" concept, and are intended to be passenger-friendly. The trains use PMSM (permanent magnet synchronous motors).
The 40000 series trains will operate on Seibu Ikebukuro Line, Seibu Shinjuku Line, and Seibu Haijima Line services. Some trainsets will be able to operate on through-running services via subway lines, with new reserved-seat supplementary-fare S-Train services planned to run between the Seibu Ikebukuro Line and Tokyo Metro Yurakucho Line on weekdays and between the Seibu Chichibu Line and Minato Mirai Line (via the Tokyo Metro Fukutoshin Line and Tokyu Toyoko Line) at weekends from 25 March 2017.
