The Tobu 500 series (東武500系, Tōbu 500-kei), branded Revaty (リバティ), is an electric multiple unit (EMU) train type operated by the private railway operator Tobu Railway on limited express services in Japan since 21 April 2017. Eight three-car sets (24 vehicles in total) were built by Kawasaki Heavy Industries.[1]


The trains were built by Kawasaki Heavy Industries, with exterior and interior styling overseen by Japanese industrial designer Ken Okuyama.[1] The driving cabs at each end of the three-car trainsets includes an automatically extending gangway connection to allow trains to be coupled or split en route.[1]

The trains have active suspension, a first for trains operated by Tobu, and use permanent-magnet synchronous motor (PMSM) traction motors.[1]


The trains are branded Revaty (リバティ), a name derived from the English words "Variety" and "Liberty".[2]
