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]
