JR East has operated previously a large number of 103 series sets on the following lines.

A single four-car 103 series set had remained in use by JR East on the Senseki Line in the Sendai area between November 2006 up until 21 October 2009.[3]

JR Central edit

JR Central has formerly used 103 series sets on Chuo Main Line services in the Nagoya area, but these were subsequently replaced by 211 series and 313 series trains.

JR-West edit

JR-West continues to operate a large number of 103 series sets, many of which have received extensive life-extension refurbishment.[4] JR-West currently operates 103 series sets on the following lines. They were also used on the Osaka Loop Line until October 2017. As of 2019, there are 63 cars still available in service.

Previous Operations (JR West):

JR Kyushu edit

JR Kyushu operated a fleet of nine 6-car 103 series sets on JR Chikuhi Line inter-running services onto the Fukuoka_City_Subway Kūkō_Line from 1982.[4][unreliable source?]

In 2015, six 6-car 305 series sets entered service and the 6-car 103 series sets were converted to 3-car sets and restricted to operating on Chikuhi Line services between Chikuzen-Maebaru and Nishi-Karatsu.[7]

As of 2018, there are six 3-car trainsets still remaining in service.

Overseas operations edit

Four former JR East 103 series 4-car units (Musashino Line sets KeYo 20, 21, 22, and 27) were shipped to Indonesia in 2004 to operate on the KRL Jabodetabek system in Jakarta.[8]

The 103–0 series trains were built between 1963 and 1981. Built for JNR as an "upgraded" version of the 101 series, the 103 series has been widely used around Japan and has been manufactured in a multitude of different body styles and configurations.

Based on the earlier 101 series, the 103 series has been used on various commuter services since 1963. In fact, some 103 series cars were actually converted from 101 series cars. The 103 series was the main rolling stock used on urban commuter services for a time.

Some sets have been used for at least 50 years, and their age is starting to show; as such, their use on various lines is diminishing and they are being replaced by newer trains. For instance, the 103 series are being replaced by the newer 323 series on the Osaka Loop Line where they famously operate.

The sets have been manufactured in a multitude of different body styles, with additional body styles being created over the years. Older sets had body styles similar to the one used on the 101 series.

Prototype edit

This 8-car unit was built in 1963 without air-conditioning. The cars were withdrawn from service between 1988 and 1991.

  • Moha 103: 901-902
  • Moha 102: 901-902
  • Kuha 103: 901-904

Standard series edit

These were built between 1964 and 1970. While not originally fitted with air-conditioning, most of the cars were fitted with air conditioning from 1975. The bogies of the trailer cars were changed from TR201 to TR212 for the cars built from 1968. Cars fitted with TR212 bogies feature disc brakes, because they needed to run on higher speeds on the Jōban and Hanwa Lines.

  • KuMoHa 103: 1-155
  • MoHa 103: 1-278
  • MoHa 102: 1-433
  • KuHa 103: 1-177 & 501-638 (TR212 bogies fitted: 115-177 & 617–638)
  • SaHa 103: 1-305 (TR212 bogies fitted: 226–305)

Air-conditioned prototype edit

This single 10-car unit was built in 1970. It was equipped with various air conditioning units and tested on the Yamanote Line in Tokyo. It was subsequently modified to become a standard air-conditioned set in 1978. In 2000, four cars were scrapped at the Narashino Depot; the remaining six cars were scrapped at Keiyō Rolling Stock Center in 2005.

  • MoHa 103: 279-281
  • MoHa 102: 434-436
  • KuHa 103: 178-179
  • SaHa 103: 306-307

Sets without air-conditioning edit

Built during 1972 and 1973, these units were similar to the air-conditioned prototype but without air-conditioning. This type was used mainly in Osaka area. Most cars were fitted with air-conditioning from 1976.

  • MoHa 103: 282-330 & 364-374
  • MoHa 102: 437-486 & 520-530
  • KuHa 103: 180-212
  • SaHa 103: 308-323

Air-conditioned sets edit

Built in 1973, they were similar to the air-conditioned prototype. They were fitted with motorized destination blinds on both sides.

  • MoHa 103: 331-413 (excluding 364–374)
  • MoHa 102: 487-569 (excluding 520–530)
  • KuHa 103: 213-268
  • SaHa 103: 324-359

ATC equipped sets edit

Built between 1974 and 1980. The front end design was changed with the driver's cab raised so that an ATC signalling system could be included. Kuha 103 of this version was used in the Tokyo area only.

  • MoHa 103: 414-713
  • MoHa 102: 570-869
  • KuHa 103: 269-796 (excluding 500–700), 798, 809, 816
  • SaHa 103: 360-471

Raised driver's cab edit

Built between 1979 and 1984. The front end design was the same as the ATC-equipped sets, although this type was not fitted with ATC. Kuha 103-811 & 816 were converted to include ATC in 1984.

  • MoHa 103: 714-793
  • MoHa 102: 870-2050 (excluding 900–2000)
  • KuHa 103: 797, 799-850 (excluding 809, 816, 845, 847, 849)
  • SaHa 103: 472-503

Converted from 101 series edit

Some 101 series trailer cars were converted to the 103–0 series. The cars' bodies and bogies were 101 series originals as the conversions involved minimum modification. The last of these cars were withdrawn from service in 1999.

  • SaHa 103: 751-780 (from SaHa 101)
  • KuHa 103: 2001-2004 (from KuHa 100), 2051-2052 (from KuHa 101)

Experimental direct-drive mechanism (DDM-VVVF) edit

(Learn how and when to remove this template message)

An insulated gate bipolar transistor traction system and direct-drive motors both manufactured by Toshiba were experimentally tested on car MoHa 103-502 (car #4) on ten-car set KeYo304 based on the Keiyō Line from May 2002; the car was originally manufactured in December 1975 by Nippon Sharyo. The direct-drive motors and IGBT inverters appear to be of the same specification as used on the experimental E993 series set due to similar cadences.

The use of direct-drive motors in the car gave the set a unique sound, with both the roar of the old-fashioned resistor-controlled traction motors and the more modern, high-pitched cadence of the variable frequency drive in car MoHa 103–502; MoHa 103-502's use of direct-drive motors gave the car itself a unique sound, as once the set reached a certain speed, the traction motors made no discernible noise.

The set entered service with the direct-drive motored car on 15 May 2003, but was retired and scrapped in December 2003 after just 7 months of service with this experimental car. Car MoHa 103-502 remains the last 103 series car to have been fitted with a variable frequency drive. No JR train since (other than the E993 and E331 series sets) has used direct-drive motors in combination with IGBT inverters.[10][unreliable source?]

160 103–1000 series cars (formed 16 10-car sets) were built in 1970 and 1971 for use on Jōban Line-Chiyoda Line inter-running services, which commenced in 1971. Originally painted in grey with a sea green stripe, they were subsequently displaced by new 203 series trains. Some sets were later converted to become 105 series sets, and the rest of the fleet was reallocated to Jōban Line services from Ueno.[11] In 1989, one Joban Line set was reallocated to the Chūō-Sōbu Line-Tōzai Line inter-running services. This set was repainted in grey with light-blue stripe, which was the same livery as the 103–1200 series. The last set was retired in March 2004.

Similar to the 103–1000 series, these were 7-car sets built by Nippon Sharyo and Tokyu Car Corporation for use on Chūō-Sōbu Line-Tōzai Line inter-running services alongside the aluminium-bodied 301 series. Five sets (35 cars) were built between 1970 and 1978. They were initially painted in grey with a yellow stripe, but this was changed to a light blue stripe from 1989 to avoid confusion with the similarly coloured 205 series trains introduced on Chūō-Sōbu Line services.[11] The last set was retired in July 2003.

Nine 103–1500 series 6-car sets were built between 1982 and 1983 by Kawasaki Heavy Industries and Hitachi for use on inter-running services between the Chikuhi Line and the Fukuoka City Subway Kūkō Line in Kyushu. In 1989, four sets were reformed as eight 3-car sets (numbered E11 to E18) by rebuilding MoHa 103 and MoHa 102 cars as KuMoHa 103 and KuMoHa 102 cars respectively. They were initially painted in light blue with a white stripe, but were repainted into a grey and red livery from 1995. The 3-car sets were modified for driver-only operation between December 1999 and March 2001.[12] Toilets were added to one end car of each set between June 2003 and October 2004.[13]

Five three-car 103–3000 series sets (numbered 51 to 55) were formed in 1985 from former 72–970 series EMU cars for use on the Kawagoe Line following electrification in September 1985. Five MoHa 72970 cars were also converted to SaHa 103-3000 cars to augment Ome Line trains. These cars were fitted with passenger-operated door controls. The five Kawagoe Line sets were lengthened to four cars between October 1995 and March 1996 ahead of Hachiko Line electrification in March 1996.[11][14] The last set was withdrawn in October 2005.

Internal training sets edit

One internal crew training set, formed as KuMoHa 103-100 + MoHa 102–224, was used for internal crew training at the JR East Crew Training Center at Higashi-Omiya Depot. The set had different cab end designs, as MoHa 102-224 used the cab of former ATC equipped KuHa 103–332, sets. It was withdrawn in 2009 following the delivery of a new 209 series-based training set in 2008.
