The E233 series is a commuter and suburban EMU type developed by East Japan Railway Company (JR East) from the earlier E231 series design. The first train was introduced in December 2006 for use on the Chūō 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 the Tōkaidō Main Line. A narrow-bodied variant will be introduced on Jōban Line and Tokyo Metro Chiyoda Line inter-running services from summer 2008.[1]

[edit] 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 the E231 series rolling stock on the Yamanote 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.
[edit] Variants
[edit] Chūō Line E233-0
The first train was introduced in December 2006 for use on the Chūō Main Line, Ōme, and Itsukaichi lines, replacing the aging 201 series trains. The entire fleet of 688 E233 series vehicles (10-car x 42, 6-car x 28, 4-car x 25) was delivered by the end of March 2008.[1] 4+6-car sets are used on the Ōme Line and Itsukaichi Line.
[edit] Keihin-Tōhoku Line E233-1000
JR East announced in September 2006 that a fleet of 83 10-car E233 series sets would also be introduced on the Keihin-Tōhoku and Negishi lines from autumn 2007, replacing the 209 series EMUs currently used. The first set was delivered in August 2007. The main difference over the earlier E233-0 is the absence of passenger door controls.
The first set was scheduled to enter service on 22 December 2007.[2] Twelve sets are due to be in operation by the end of fiscal 2007.[3]
[edit] Jōban Line E233-2000
A new narrow-bodied variant is scheduled to be introduced on Jōban Line and Tokyo Metro Chiyoda Line inter-running services from summer 2008, replacing the 203 series and 207 series EMUs currently used.[4]
[edit] Tōkaidō Main Line E233-3000
A single 10+5-car E233-3000 series outer suburban set (E01 + E51) for use on the Tōkaidō Main Line was delivered to Kōzu Depot in November 2007. This includes two bilevel Green cars.[5] The set entered revenue service on 10 March 2008. It is limited to use on the Tōkaidō Main Line between Tokyo and Atami. [6]
