The Seibu 40000 series (西武40000系) is a commuter electric multiple unit (EMU) train type operated by the private railway operator Seibu Railway in Japan since March 2017.[1] 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 on 25 March 2017.[2]

Design

The new 40000 series trains were built by Kawasaki Heavy Industries in Kobe from January 2016, with deliveries scheduled to continue from fiscal 2016 to 2019.[3] This is the first time that trains for Seibu Railway have been built by this manufacturer.[3]

The new trains are designed as an evolution of the 30000 series "Smile Train" concept, and are intended to be passenger-friendly.[1] The trains use PMSM (permanent magnet synchronous motors).[1]

Operations

The 40000 series trains will operate on Seibu Ikebukuro Line, Seibu Shinjuku Line, and Seibu Haijima Line services.[4] Some trainsets operate on reserved-seat supplementary-fare S-Train services 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 since 25 March 2017.[5][6]

Formation

The 40000 series EMUs are ten-car sets formed as follows, with five motored ("M") cars and five non-powered trailer ("T") cars, and car 1 at the Hanno (i.e. northern) end.[2]

Cars 2, 5, and 8 each have one single-arm pantograph.[2] Car 4 has a universal access toilet.[2]

Interior

Passenger accommodation consists of longitudinal bench seating, but some trainsets feature rotating pairs of seats that can be arranged in either longitudinal or transverse arrangements.[1] LED lighting is used in the interiors, and pairs of LCD passenger information screens are provided both above the doorways and suspended form the ceilings.[2] A "Partner zone" area is provided at the end of car 10 with perch seats and space for wheelchairs and large luggage.[2] This area also has larger windows.[2] "Plasmacluster" air-purification technology is used for the first time on Seibu Railway trains.[4]

History
