East Japan Railway Company (JR East) from the earlierE231 series design. The first train was introduced in December 2006 for use on theChūō Main Line , followed by the E233-1000 series variant in 2007 for use on the Keihin-Tōhoku and Negishi lines, and the E233-3000 series outer-suburban variant in December 2007 for use on theTōkaidō Main Line . A narrow-bodied variant will be introduced onJōban Line andTokyo Metro Chiyoda Line inter-running services from summer 2008. [http://www.jreast.co.jp/press/2006_2/20070303.pdf]Design details
The E233 series, according to the October 2005 press release, features two identical sets of the main equipment in case of failure. This is the first JR East stock to feature such backup measures.
The E233 series provides for better accessibility for the disabled, and is designed to be more comfortable to ride overall than conventional stock. The height between the platform and the train was reduced from the 80 mm of the 201 and 209 series to 30 mm. Seats are 460 mm wide, compared to the 430 mm of the 201 series and 450 mm of the 209 series. For standing passengers the handle straps have been lowered with 50 mm compared to older train models.
This stock also features an air filtration system to remove unpleasant smells. It also features
liquid crystal display information screens and automatic announcement system similar to those currently deployed on theE231 series rolling stock on theYamanote Line .The stock is the first JR East stock to use full-colour LEDs for the destination indicators on the sides of the carriages. This is due to the fact that the Chūō line has numerous types of services, and colour-coding will help passengers board the correct train.
