New Rolling Stock to be Introduced on Keihin-Tohoku Line and Negishi Line
—Series E233 direct current electric railcars—

East Japan Railway Company

September 5, 2006

East Japan Railway Company is moving ahead with plans to introduce new rolling stock on suburban routes in the Tokyo Metropolitan area. We finished replacing all old-style trains on the Yamanote Line in April 2005 and will be introducing new railcars on the Chuo Line (rapid service) from December this year. Through such initiatives, we are further enhancing the reliability of trains and improving the service we offer. As well as enhancing accessibility for all passengers, we are installing screens in new trains to provide passengers with service-related and other information.
Next, we will introduce new railcars on the Keihin-Tohoku and Negishi Lines. These cars will be the series E233, the same as those being brought into service on the Chuo Line (rapid service). These railcars offer passengers the following benefits.

  • The new cars feature backups for the main equipment, including electric equipment and safety devices. This means the train can continue running even if one out of a pair of devices fails, which reduces service disruptions.
  • Universal Design has been employed to provide enhanced comfort and usability for passengers. The heights of luggage racks and hand straps have been lowered around priority seating and in other areas, and the priority seating areas have been made clearly visible.
  • The floor has been lowered to reduce the step between the train and the platform, thereby increasing accessibility for all passengers.
  • Information displays screens have been installed above doors to provide passengers with service-related information, news and other information.
1.  Number of cars to be manufactured 830
2. Cars to be introduced New cars are scheduled to be brought into service from autumn 2007.
3. Lines on which the new cars will be used     Keihin-Tohoku Line and Negishi Line (Omiya to Ofuna via Yokohama)
4. Overview of rolling stock
