The Odakyu 4000 series (小田急4000形 Odakyū 4000-gata) is a 1,500 V DC commuter electric multiple unit (EMU) train type operated by the private railway operator Odakyu Electric Railway in Japan since 2007.[2]

Design

The trains are based on the JR East E233 series EMU design, but with narrow bodies to permit subway running.[2] The traction motors are fully enclosed to reduce environmental noise.[2]

History

The first train was delivered in May 2007, and the trains entered service in September 2007 on inter-running services between Odakyu and the Tokyo Metro Chiyoda Line, displacing 1000 series sets, which were cascaded to surface lines to replace older 5000 and 5200 series sets.
