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] As of November 2023,[update] a total of 20 ten-car trainsets have been 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 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]
Due to the use of fixed longitudinal seating throughout, the 40050 subseries EMUs are slightly lighter and accommodate more passengers than the 40000 series trains.[7]

Interior
The trains' interiors use LED lighting, 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
Details of the new trains were officially announced in August 2015.[1] The first trainset, 40101, was delivered from the Kawasaki Heavy Industries factory in Kobe to Seibu's Kotesashi Depot in September 2016.[9]
The first sets entered revenue service on S-Train services on 25 March 2017.[10]
From spring 2018, 40000 series trains are scheduled to be used on new Haijima Liner (拝島ライナー) limited-stop supplementary-fare commuter services operating from Seibu-Shinjuku to Haijima on weekday evenings.[11]
In 2019, Seibu announced plans to procure two new 40000 series trainsets.[12] These sets, numbered 40151 and 40152, were built with fixed longitudinal bench seating throughout instead of rotating seats found in older sets.[8] Two additional sets with fixed longitudinal seating were announced in 2020 as part of the operator's investment plan for fiscal 2020,[13] followed by another three for 2021.[14] By November 2023, fourteen 40000 series sets with fixed longitudinal seating had been built.[15]
