Seibu's SAMURAI BLUE TRAIN

Set 40156 of Seibu’s 40000 series EMU fleet, the SAMURAI BLUE TRAIN

Is the FIFA World Cup creating a huge buzz in your country?

In Japan, yes. As evidence, the Bureau of Waterworks of the Tokyo Metropolitan Government recently released data on “match-day changes in water distribution volume” and found that water usage increased sharply just before kickoff, during halftime, and immediately after the final whistle. I hope you can imagine what that means.

I’m not a soccer enthusiast, but as a train enthusiast, I can’t get World Cup-related trains out of my mind.

For example, on June 7, Seibu Railway introduced a specially wrapped train, the SAMURAI BLUE TRAIN.

Please take a look at the top photo—yes, this is the SAMURAI BLUE TRAIN. You can see the vibrant two-tone blue and green livery on the train. The blue represents the team color of Japan’s national team. Meanwhile, the blue and green also represent the corporate colors of the sponsor, Credit Saison.

Along the sides of the train, you can see players from the national team. For example, the bottom photo shows Kubo Takefusa, who plays as a right winger. He is very popular with children because he is kind to them. He has a small build, but he is very fast—like JR East’s Series E6 Shinkansen EMU. Is this analogy a bit of a stretch?

As a train enthusiast, I would also like to touch briefly on the technical aspects of the train itself. The SAMURAI BLUE TRAIN is Set 40156 of Seibu’s 40000 series EMU fleet. The 40000 series entered service in 2017. A total of 26 sets, or 248 cars, were introduced between 2017 and 2025. Each car has a 20-meter aluminum-alloy body and an IGBT-based VFD traction system with 190 kW fully enclosed permanent-magnet synchronous motors. All 40000 series trains also have a special space called the “Partner Zone” for wheelchair users and passengers with prams.

For your information, there are several variations within this fleet. For example, 20 sets, including Set 40156, are composed of 10 cars, while the other six sets consist of 8 cars. Another difference is that six sets have convertible cross/long seats and a wheelchair-accessible restroom, while the other 20 sets, including Set 40156, have longitudinal seating only. Furthermore…

Sorry to be so specific... I always geek out over this kind of topic.
