The original full-production version introduced on both the Keihin-Tōhoku (10-car sets) and Nambu (6-car sets) lines in 1993. 6-door SaHa 208 cars were inserted into the Keihin-Tōhoku Line sets in 1995.
The 209 series trains on the Keihin-Tōhoku/Negishi lines were replaced by new E233 series trains from autumn 2007, with the last sets withdrawn by 24 January 2010.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- and six-car sets for use in the Chiba area.
The former Nambu Line six-car sets were formed as follows, with car 1 at the Kawasaki end.
Cars 2 and 4 were each equipped with one PS28 lozenge-type pantograph.
The former Keihin-Tohoku Line ten-car sets were formed as follows, with car 1 at the Ofuna (southern) end.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.
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. The 17 ten-car sets differ noticeably from the other 209 series variants in having 2,966 mm wide cars (compared to 2,870 mm 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. Five sets were transferred to the Keihin-Tōhoku Line, and, from October 2008, these were modified (with ATS-P/SN instead of ATC), repainted, and transferred to the Keiyō Line following the introduction of new E233 series trains. From September 2010, three former Keiyō Line sets were reduced to eight cars and reliveried for use on the Musashino Line, entering service from 4 December 2010.
As of 1 October 2016, 13 ten-car sets (C501 to C512 and C516) were allocated to Mitaka Depot for use on the Chuo-Sobu Line, and one set (34) was allocated to Keiyo Depot for use on the Keiyo Line. These sets are formed as follows with four motored ("M") cars and six non-powered trailer ("T") cars.
The two MoHa 209 cars each have one pantograph (lozenge type on sets C501 to C509, and single-arm type on sets C510 to C516 and 34).
As of 1 October 2016, three eight-car sets (M71 to M73) were allocated to Keiyo Depot for use on Musashino and Keiyo Line services. These sets are formed as follows with four motored ("M") cars and four non-powered trailer ("T") cars. Car 1 is at the Tokyo end.
The two MoHa 209 cars (cars 2 and 6) each have one single-arm pantograph. Car 4 is designated as a mildly air-conditioned car.
Three ten-car prototypes were built in 1992 for testing and passenger evaluation on the Keihin-Tōhoku Line, initially classified as 901 series. Set A was built by Kawasaki Heavy Industries, set B by 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 B became 209-910 series, and set C became 209-920 series. They differed from the full-production 209-0 series sets in not having six-door SaHa208 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 Tokyo General Rolling Stock Center.
This was the original classification given to the prototype E231 series 10-car set delivered in October 1998. It was reclassified as E231-900 series in June 2000 following conversion to the full-production E231 standard.
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 are based at JR East's Matsudo depot.
Cars 3, 6, and 9 are fitted with PS21 lozenge type pantographs.
These are four- and six-car sets based at Makuhari Depot modified in 2009 from former Keihin-Tōhoku Line 209-0 series ten-car sets for use on Chiba area and Bōsō Peninsula local services from 1 October 2009. The first four-car set was outshopped from Nagano Works in June 2009. Modifications include new electrical equipment, the addition of transverse seating, LED destination indicator panels, and a toilet. The cars are numbered in the -2100 series, although some 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.
As of October 2016, 42 four-car sets and 26 six-car sets were in service.The end cars have some transverse seating bays.
Car 2 is fitted with a toilet.
The MoHa 209-2100 cars are fitted with one lozenge-type pantograph.
The first six-car set, C602, was outshopped from Ōmiya Works in July 2009.The end cars have some transverse seating bays.
Car 2 is fitted with a toilet.
The MoHa 209-2100 cars are each fitted with one lozenge-type pantograph.
These are 6-car sets reformed in 2009 from former Keihin-Tōhoku Line 209-0 series 10-car sets for use on Nambu Line services, replacing the early-batch 209-0 series set and a 205-1200 series set. The first set, number 52, was outshopped in May 2009, and entered service on 12 June 2009. Modifications include new electrical equipment and the addition of LED destination indicator panels.
The last remaining 209-2200 series trainset, set 53, is scheduled to be replaced from 15 March 2017.
As of 1 October 2016, one six-car set is in service, set 53, formed as follows, with car 1 at the Kawasaki end.
Cars 2 and 4 are each equipped with a PS28A single-arm pantograph.
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) are 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.
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.
The four sets, 61 to 64, are formed as shown below, with car 1 at the Komagawa end and car 4 at the Kawagoe end.
Car 3 is fitted with one PS28 lozenge-type pantograph.
This sub-series of two 4-car sets was introduced on 17 April 2005 as part of the scheme to eliminate 103 series sets from the Kawagoe Line and Hachikō Line. Set number 71 consists of two former TWR 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 6-car sets were reformed into 10-car sets in 2004. Like the 209-3000 series, these sets have passenger-operated door controls.
The two sets, 71 and 72, are formed as shown below, with car 1 at the Komagawa end and car 4 at the Kawagoe end.
Car 3 is fitted with one PS28 lozenge-type pantograph.
The identities of the six former 70-000 series cars converted in 2004 and 2005 to become 209-3100 series EMUs are as shown below.
A purpose-built four-car set based directly on the 209-0 series design and classified E991 series was delivered to JR East's training centre in Shirakawa, Fukushima in 2000 for internal training use. Externally, it is finished in shōnan green/orange stripes on unpainted stainless steel.
A two-car set was converted from former Keihin-Tōhoku Line end cars in 2008 for use as a staff training set at JR East's Ōmiya Training Center. This replaced the former 103 series two-car set previously used there. The set is formed of KuMoHa209-76 + KuMoHa208-76, and is finished in the shōnan green/orange colour scheme.
Another two-car set was converted from former Keihin-Tōhoku Line end cars at Nagano Works, and moved to the JR East Yokohama area training centre next to Kurihama Station in July 2008, replacing the 105 series 2-car set previously used there. The set is formed of KuMoHa 209-092 + KuMoHa 208-092, converted from former intermediate cars MoHa209-39 + MoHa208-39, with cabs newly added, and features pale yellow bodyside stripes bearing the lettering "YOKOHAMA Training Center".
A third two-car set was converted from former Keihin-Tōhoku Line end cars at Nagano Works, and moved to the JR East Hachiōji area training centre next to Shin-Akitsu Station in October 2008, replacing the 105 series two-car set previously used there. The set features orange bodyside stripes bearing the lettering "HACHIOJI Training Center".
In October 2008, JR East unveiled the seven-car "MUE-Train" (MUltipurpose Experimental Train) experimental EMU converted from former Keihin-Tōhoku Line 209 series cars. This set is used to test and develop new technology for use on future narrow-gauge trains. The train is based at Kawagoe Depot and began testing on the Utsunomiya Line from November 2008.
Cars 3 and 6 are each fitted with one PS33D single-arm pantograph.KuHa 901-1 (previously KuHa 209-901), at the Tokyo General Rolling Stock Center in Shinagawa, Tokyo
