Odakyu 3000 series

The Odakyu 3000 series is an electric multiple unit commuter train type operated by the private railway operator Odakyu Electric Railway in Japan. First introduced on 10 February 2002, a total of 336 cars were built with orders divided between Nippon Sharyo, Tokyu Car Corporation, and Kawasaki Heavy Industries. Originally formed as six- and eight-car trainsets, additional cars have been built since 2010 to augment pre-existing sets to ten cars.

10-car set introduction

In 2010, Odakyu announced plans to procure eight cars to extend six-car sets to 10-car sets. These cars were delivered between 2010 and 2011 from Kawasaki Heavy Industries' Hyogo plant and used to augment six-car sets 3280 and 3281 to 10 cars; the sets were renumbered 3091 and 3092, respectively. The first 10-car set, 3091, entered service on 20 January 2011.
five additional 10-car sets have since been introduced: 3081, 3082, and 3093–3095.

Refurbishment

Beginning in fiscal 2022, the 3000 series has undergone a programme of refurbishment, which includes additional wheelchair spaces, surveillance cameras, and energy-saving control equipment.

Livery variations

Doraemon-liveried "F-Train"

In August 2011, 10-car set 3093 was reliveried in a Doraemon livery to commemorate the opening of the Fujiko F. Fujio Museum in Kawasaki, Kanagawa. The train was scheduled to run in its livery for one year, but this was cut short due to complaints from the Tokyo Metropolitan Government that it violated metropolitan ordinances regulating advertising on train exteriors. The decorated "F-Train" remained in service until 30 September 2011, before the exterior advertising was removed.
Set 3093 returned to service with a redesigned Doraemon livery, named "F-Train II", on 20 July 2012. It was scheduled to carry this livery until 22 March 2013.
