209-1000 Series

The is an electric multiple unit (EMU) commuter train type operated by East Japan Railway Company (JR East) in the Tokyo area of Japan since 1993.

The series was introduced in 1992 for experimental operations (as the 901 series) and in 1993 for commercial operations to replace the aging 103 series stock on the Keihin–Tōhoku Line, Keihin–Tōhoku and Negishi Line, Negishi lines. The concept of the 209 series was to create a lower-cost, minimal lifespan train (approximately 15 years) that would be replaced rather than rebuilt when they became life-expired.

The 209 series was the first of the , and served as the basis for the E501 series, E501, E217 series, E217, 701 series, 701, and E127 series rolling stock, as well as the succeeding E231 series stock, which in turn became the blueprint for successive trains developed by JR East and other railway companies in Japan.

209-0 series

The original full-production version introduced on both the Keihin–Tōhoku Line, Keihin–Tōhoku—Negishi Line, Negishi (78 ten-car sets numbered 1–78) and Nambu Line, Nambu (2 six-car sets numbered 1 and 32) lines in 1993. Six-door SaHa 208 cars were inserted into the Keihin–Tōhoku—Negishi Line sets in 1995.

The 209 series trains on the Keihin–Tōhoku—Negishi Line were replaced by new E233 series#E233-1000 series, E233-1000 series trains from autumn 2007, with the last sets withdrawn by 24 January 2010. A large number of these units were subsequently rebuilt as 209-2000/2100 series four-car and six-car sets for use in the Chiba area, while some were converted as training sets, MUE-Train, or 209-2200 series sets for the Nambu Line.

Formations

Keihin–Tōhoku—Negishi Line 10-car sets

Previously, 78 ten-car sets (1–78) were based at Urawa depot and were formed as shown below, with four motored ("M") cars and six non-powered trailer ("T") cars.

* Cars 3 and 8 were each equipped with one PS28 pantograph.
* Car 6 was a "6-door" car with six pairs of doors on each side.

209-500 series

This sub-series represented a stop-gap for use from 1998 on the Chūō–Sōbu Line until the full-production E231 series trains were delivered, and a total of 17 ten-car sets (numbered 51–67) were delivered to Narashino Depot in Chiba. These sets differ noticeably from the other 209 series variants in having wide cars (compared to for earlier flat-sided stock), as well as LED destination indicators, replacing the earlier roller blind type. While externally similar in appearance to the later E231 series sets, the 209-500 series are distinguishable by their white cab fronts and lack of six-door cars.

In November 2000, two sets (66 and 67) were transferred to the Keihin–Tōhoku Line, Keihin–Tōhoku—Negishi Line and renumbered 80 and 81. In December 2003, the Chūō–Sōbu Line sets were reallocated to Mitaka Depot and renumbered 501–515. Between 2005 and 2006, set 515 was lent to the Keihin–Tōhoku—Negishi Line as a spare during car maintenance. Between 2006 and 2007, three more sets (513–515) were transferred to the Keihin–Tōhoku—Negishi Line to replace the prototype #209-900/910/920 series, 209-900/910/920 series trains and renumbered 82–84. From October 2008, following the introduction of E233 series#E233-1000 series, E233-1000 series trains on the Keihin–Tōhoku—Negishi Line, one set (80) was transferred back to the Chūō–Sōbu Line (as set 516) while the other four sets (81–84) were modified (with ATS-P/S_N instead of ATC) and transferred to the Keiyō Line (as sets 31–34).

From September 2010 to January 2011, three former Keiyō Line sets (31–33) were reduced to eight cars and reliveried for use on the Musashino Line, renumbered M71–M73, and entered service from 4 December 2010. In 2012, a "C" suffix was added to all Chūō–Sōbu Line sets (C501–C512 and C516).

From 2018, five Chūō–Sōbu Line sets (C501–C505) were converted to 4-car #209-3500 series, 209-3500 series sets for use on Kawagoe Line and Hachikō Line services, while the remaining eight sets (C506–C512 and C516) were reduced to 8 cars and reallocated to the Musashino Line and renumbered M74–M77 and M81–M84. The last Chūō–Sōbu Line set, set C511, was withdrawn from service on 19 April 2019.

All sets were refurbished between 2016 and 2019, when the GTO-VVVF traction system was replaced with an IGBT-VVVF traction system.

209-900/910/920 series

Three ten-car prototypes were built in 1992 for testing and passenger evaluation on the Keihin–Tōhoku—Negishi Line, initially classified as 901 series. Set A was built by Kawasaki Heavy Industries, set B by Japan Transport Engineering Company, Tokyu Car Corporation, and set C was built by Kawasaki Heavy Industries and JR East's Ōfuna factory (cars 4 and 5). The three sets incorporated a number of different design features for evaluation, but were converted in 1994 to bring them in line with the full-production specifications. Set A became 209-900 series set 90, set B became 209-910 series set 91, and set C became 209-920 series set 92. They differed from the full-production 209-0 series sets in not having six-door SaHa 208 cars.

209-910 series set 91 was withdrawn in December 2006, and the last of the three prototype sets, set 90, was withdrawn in August 2007. Car KuHa 209-901 from the original 901 series set A was stored at Nagano Works, and later preserved at Tōkyō General Rolling Stock Center.

Formation

209-950 series

This was the original classification given to the prototype E231 series 10-car set delivered in October 1998, to test out the then-new insulated-gate bipolar transistor (IGBT) traction system and ''TIMS'' passenger information system. It was reclassified as E231-900 series in June 2000 following conversion to the full-production E231 standard.

209-1000 series

Two 10-car sets (81 and 82) were delivered from Tokyu Car Corporation in August and September 1999, entering service from 4 December 1999 on Jōban Line and Tokyo Metro Chiyoda Line inter-running services. Based on the 209-0 series, these trains have end doors for use in emergencies inside tunnels. These sets were based at JR East's Matsudo depot. These train sets have since been withdrawn from the Jōban Line in October 2018 and reallocated to the Chūō Line (Rapid) in December 2018, being based at JR East's Toyoda Depot after the reallocation. Operations officially started on the Chūō Line in March 2019.

While these sets usually operate only between Tokyo and Takao, on rare occasions (such as a shortage of train sets due to an accident) they may operate as far as Ōtsuki, or on the Ōme Line as far as Ōme. Furthermore, unlike the E233 series in use, due to the lack of passenger-operated door controls, all doors open on these sets while in use on the Ōme Line.

Formation

As of 1 January 2020, two 10-car sets (81–82) are allocated to Toyoda Depot and are formed as follows with six motored ("M") cars and four non-powered trailer ("T") cars.

* Cars 2, 5 and 8 each have one single-arm pantograph.
* Cars 2 and 9 have wheelchair space.
* Car 4 is designated as a mildly air-conditioned car.

Previous formation

10-car Jōban Line sets (1999 to 2018)

* Cars 3, 6 and 9 were originally fitted with PS21 lozenge type pantographs, but were converted to single-arm models in 2014.
* Cars 2 and 9 had wheelchair space.
* Car 4 was designated as a mildly air-conditioned car.

209-2000/2100 series

These are four- and six-car sets based at Makuhari Depot modified between 2009 and 2013 from former Keihin–Tōhoku—Negishi Line 209-0 series ten-car sets for use on Chiba (city), Chiba area and Bōsō Peninsula local services from 1 October 2009 to replace ageing 211 series trains. Modifications include new electrical equipment, the addition of transverse seating to end cars, LED destination indicator panels, and a toilet. The cars are numbered in the -2100 series, although nine four-car sets have end cars numbered in the -2000 series. The -2000 series cars are converted from early batch 209-0 series units with air-operated doors rather than the electrically operated doors of later batch units.

The first four-car set (C417) was outshopped from Nagano Works in June 2009, while the first six-car set (C602) was outshopped from Ōmiya Works in July 2009. The entire conversion process was completed in 2013, and a total of 42 four-car sets (C401–C442) and 26 six-car sets (C601–C626) were formed.

From 13 March 2021, they were replaced on rural services with new E131 series trains. Six 6-car sets were shortened to 4-car sets between February to March 2021; the two surplus cars from each set along with three others 6-car sets (C612, C618, C626) were scrapped between April and May 2021.

In July 2021, 6-car set C609 was removed from JR service and delivered to Izukyū Corporation, and four cars from set C601 were delivered in November 2021. They are expected to enter service in Spring 2022 as the Izukyu 3000 series.

209-3000 series

Four four-car 6th-batch sets were introduced on 16 March 1996 for use on the Kawagoe Line and newly electrified southern section of the Hachikō Line. These sets (numbers 61 to 64) were based at JR East's Kawagoe depot. While visually similar to the original 209-0 sub-series, these sets differ in having passenger-operated door controls.

These sets were displaced by newly refurbished E231-3000 series and #209-3500 series, 209-3500 series sets entering service from 2017 and 2018, with the last set withdrawn in February 2019. In late 2018, two cars of set 62 were formed into a #Training sets, training unit and the other two cars were scrapped; the remaining three sets were scrapped in early 2020.

Interior

For a short period in 2004, KuHa 209-3003 of set 63 was fitted with transverse seating bays to increase seating capacity. It was later reverted to standard longitudinal bench seating.

Between February and March 2007, some of the previously sealed windows in each car were modified to allow them to be opened.

Build details

209-3100 series

This sub-series of two four-car sets was introduced on 17 April 2005 as part of the scheme to eliminate 103 series sets from the Kawagoe Line and the Hachikō Line. Set number 71 consists of two former TWR 70-000 series, Tokyo Waterfront Railway 70-000 series control cars with two newly manufactured intermediate cars, while set number 72 consists entirely of former 70-000 series cars. The 70-000 series cars had become surplus when six-car sets were reformed into ten-car sets in 2004. Like the 209-3000 series, these sets have passenger-operated door controls.

After being displaced by the #209-3500 series, 209-3500 and E231 series#E231-3000 series, E231-3000 series sets, these sets were taken out of service in October 2019. However, they re-entered service and served as additional trains as the 209-3500 and E231-3000 series sets were modified for wanman driver-only operations. They were removed from service in January 2022 after a special retirement tour event; the sets were then officially retired on 11 March 2022.
