Tobu N100 series

The Tobu N100 series, branded Spacia X, is an electric multiple unit train type that the private railway operator Tobu Railway has run on limited express services in Japan since 15 July 2023. Four six-car sets were built by Hitachi, with the first two sets, N101 and N102, delivered from the Kasado plant of Hitachi from March 2023 and the last two from February 2024. The class was bought to replace the older 100 series Spacia trains that had been in service since 1990, and it serves as the flagship limited express fleet of Tobu. It belongs to the A-train family of Hitachi and has an aluminium body. The design received the 2023 Good Design Award and the 2024 Blue Ribbon Award of the railway press.
