DesignEdit

Introduced in 1994 to replace the 113 series EMUs running on the Sōbu Line (Rapid) and Yokosuka Line, it was the first outer-suburban train type in Japan to feature four pairs of doors per side on car. The basic design was developed from the 209 series commuter EMUs. It replaced all the Yokosuka Line 113 series trains by 1999. The trains were built jointly by Kawasaki Heavy Industries, Tokyu Car, and JR East (Niitsu and Ofuna factories).[2]

They use Mitsubishi IGBT transistors (formerly GTO) and VVVF inverters with Mitsubishi MT68/73 traction motors. The gear ratio is 97:16.

HistoryEdit

 
Refurbished (left) and unrefurbished (right) sets, August 2008

The E217 series trains entered revenue service from 3 December 1994.[13]

From December 2001, 11-car trains were used on the Shōnan–Shinjuku Line between Shinjuku and Zushi. This continued until October 2004 when Shōnan–Shinjuku Line services were unified using E231-1000 series trains.

In March 2006, three 15-car trains were reformed as 10+5-car sets and transferred to Kōzu depot for use from 14 March 2006 on Tōkaidō Main Line duties out of Tokyo alongside E231-1000 series trains. The sets were repainted into the same Shonan color scheme of orange and green bodyside stripes as applied to the E231s. These sets were all transferred back to Yokosuka/Sōbu Line services by March 2015.

A program of refurbishment on the fleet commenced in 2008 and was completed in 2012. Externally, sets received lighter blue and cream stripes.

The sets are being replaced by the newer E235-1000 series and transferred to Nagano depot for scrapping since the fiscal year 2020. The first withdrawn set was transferred to Nagano between January 5 and 6, 2021.[6]

IncidentsEdit

On December 25, 2014, an 11+4 car train consisting of sets Y12 and Y129 broke down on the Yokosuka Line due to electrical problems; another 11+4 car train consisting of sets Y23 and Y130 was sent to tow the faulty set from Tokyo Station to Kamakura Depot, creating an immensely long thirty-car train. While this was happening, the entire train did not stop at any stations to pick up any passengers.
