The Korail Class 1000 trains are EMUs in South Korea for use on Seoul Subway Line 1. Class 1000 trains were built in and entered service between 1974 and 1997. The majority of Class 1000 trains have been retired; only third batch trains with third batch driving cars remain in service as of April 2017.

Technical details

South Korea had no experience of manufacturing and operating EMUs, so Japan built the first Class 1000 trains in 1974. As a result, the first Class 1000 trains were based on Japanese trains, but then later on, Korean companies changed the design of these trains, both mechanically and aesthetically. Electric parts were based on JNR 415 series, while the carbody was based on the JR 103 series cars.

Formation

The Class 1000 cars are arranged in 10-car trains. All trains use 6 motor (M) cars and 4 trailer (T) cars in a TC-M-M'-T-M-M'-T-M-M'-TC formation. Details of the car types are listed below:

  • 10XX - Tc (trailer driving car)
  • 12XX - M (air compressor, battery, main resistor and controller)
  • 13XX - M' (transformer, SIV, pantograph)
  • 18XX - T (trailer car)
  • 14XX - M
  • 15XX - M'
  • 19XX - T
  • 16XX - M
  • 17XX - M'
  • 11XX - Tc

An M-M' car pair is numbered 12XX-13XX, 14XX-15XX, or 16XX-17XX, respectively, and there can be multiple trains with the same first 2 digits (such as two 16XX-17XX pairs). Additionally, trailer cars (such as two 19XXs instead of a 18XX/19XX pair) have been irregularly placed as well. The final formation of trains 1-60~1-61 (since retired) was a TC-M-M'-M-M'-M-M'-M-M'-TC formation (four pairs of M-M' car pairs with no trailer car pairs) that allowed for a slightly faster acceleration.

Older Formations

When Seoul Subway Line 1 first opened, the Class 1000 cars were arranged in six-car trains, and were expanded to eight-car trains between 1980-1981 before being expanded to 10 cars by the 1990s. A six-car formation was as following (where YY is one integer greater than XX):

  • 10XX - Tc (trailer driving car)
  • 13XX - M (air compressor, battery, main resistor and controller)
  • 16XX - M' (transformer, SIV, pantograph)
  • 13YY - M
  • 16YY - M'
  • 10YY - Tc

An eight-car formation was as following (where YY is one integer greater than XX, and ZZ is one integer greater than YY):

  • 10XX or 11XX - Tc (trailer driving car)
  • 13XX or 14XX - M (air compressor, battery, main resistor and controller)
  • 16XX or 17XX - M' (transformer, SIV, pantograph)
  • 13YY or 14YY - M
  • 16YY or 17YY - M'
  • 13ZZ or 14ZZ - M
  • 16ZZ or 17ZZ - M'
  • 10ZZ or 11ZZ - Tc

Batches

First Generation

First batch car 1115 preserved at the Korean Railroad Museum.

Trains 1-01~1-41 were 1st generation trains and were introduced from 1974 to 1979. Their general appearance was similar to Japanese EMUs built around their time; the earliest cars were even assembled by various Japanese railcar manufacturers. All other cars were built by Korean companies including Daewoo Heavy Industries under license. All trains were assigned to Guro Depot and had the old Korean National Railroad (KNR) livery up to their retirement. The cars are nicknamed the initial rheostat cars (초저항).

The first generation of Seoul Metro 1000-series trains are identical to these trains, and other Seoul Metro trains had their designs derived from these trains.

Batch 1

The first batch of 1st generation trains consisted of 126 cars that were originally linked as 21 six-car trains. The cars were manufactured in 1974 under Kawasaki Heavy Industries, Kinki Sharyo, Tokyu Car Corporation (now JTEC), and Nippon Sharyo.

As ridership increased on Line 1, the trains were rearranged into eight-car trains in the 1980s. As this rearrangement occurred, seven of the trains lost their four motor cars, which were given to the other 14 cars. In place, 42 motor cars were manufactured in Korea between 1980 and 1981 for the seven donor trains. Finally, the trains were extended to ten cars from 1984 to 1985 with two unpowered cars each manufactured in Korea during that time.

In the 1990s, the trains received their current numbers. The 14 trains that utilized eight Japanese-made cars were numbered as trains 1-01~1-14, while the seven that lost their original motor cars were renumbered to 1-29~1-35.

The train that became train 1-02 was involved in an accident at the Hankuk University of Foreign Studies station on October 2, 1984, that led to two damaged cars (a driving car and a motor car) being scrapped and the rest of the train being placed out of service. The train that became train 1-14 experienced a similar accident at Incheon station and received the driving car that survived from the 1984 accident to replace the one driving car that was heavily damaged. In turn, the two driving cars in the out-of-service train were eventually replaced by second batch driving cars, and the motor car was replaced by a new car built in 1986.

The trains were replaced by the Class 311000 trains. They were retired between 1998 and 1999, except for train 1-02, which was kept in service until June 2004. After trains 1-29~1-35 were retired, their motor cars were linked with other trains until 2006, and their unpowered cars (1829-1835 and 1929-1935) were rebuilt into driving cars by Rotem in 2002 and received new front ends. They were renumbered to cars 1088-1094 and 1188-1194 and were linked with newer first generation cars. The cars were replaced with 3rd generation Class 311000 trains and taken out of service in 2006 when they finally reached their 25-year lifespans, and were stored at the Byeongjeom Car Depot until 2011, when they were finally taken off property to be scrapped or repurposed.

Batch 2

The second batch of 1st generation trains consisted of 126 cars that were originally linked as 21 six-car trains. The cars were manufactured from 1976 to 1979 under Daewoo Heavy Industries.

As ridership increased on Line 1, the trains were rearranged into eight-car trains in the 1980s. As this rearrangement occurred, seven of the trains lost their four motor cars, which were given to the other 14 cars. In place, 26 motor cars were manufactured in Korea between 1980 and 1981 for four of the seven donor trains; one received only two motor cars and ran as a four-car train on the Yongsan-Seongbuk shuttle line, and the other two (four driving cars) were held out of service. In 1984, the 18 eight-car trains were extended to ten cars, the four-car train was extended to eight cars, a new four-car train was formed, and the remaining two driving cars were donated to the train that would become train 1-02. Finally, in 1989, the two eight-car trains and the four-car train were extended to ten cars with second generation cars built then.

In the 1990s, the trains received their current numbers. The 14 trains that utilized eight original cars were numbered as trains 1-15~1-28, while the remaining six that lost their original motor cars were renumbered to 1-36~1-41.

The trains were replaced by the Class 311000 trains. They were gradually retired between 2000 and 2004; the last trains, trains 1-26~1-28 and 1-41, were retired in June 2004. However, the motor cars in trains 1-36~1-41 and all unpowered cars were saved from retirement and linked with other trains until at least 2006. Many of the cars built from 1984 to 1986 were even refurbished in 2006-2007 and were not retired until September 2014, when the final unpowered cars in 2nd generation train 1-55 were retired with the rest of train 1-55, marking the end of service life of the 1st batch trains. Both unpowered cars of 1-39~1-40 and one car in train 1-41 were converted into unpowered cars formerly found in Class 311000 trains 311-39~311-41.[1] Cars 1441, 1541, 1641, and 1741 were used in 2nd batch trains after the retirement of train 1-41, but all cars were retired with train 1-58 on May 1, 2010, when the whole train was damaged in an accident.[2]

Second Generation

Refurbished 2nd batch car 1182 (ex-1942) at Yeongdeungpo Station as a Yongsan-Dongincheon express train.

Trains 1-42~1-73 are 2nd generation trains and were introduced from 1986 to 1992. The 2nd batch trains were introduced to supply more trains to Line 1. Several additional 2nd generation cars were built to lengthen first generation trains to ten cars.

The 2nd generation featured a redesigned car body. The front end of the train was changed completely, and a train event recorder was introduced. Unlike the 1st generation trains, the 2nd generation trains were delivered with air-conditioning; thus SIV systems were introduced to power the air conditioners. All trains had the old Korean National Railroad (KNR) livery, but have received the new livery following overhaul. Trains 1-42~1-63 were built from 1986 to 1989 with long, rectangular-windowed doors while trains 1-64~1-73 were built from 1991 to 1992 with short, square-windowed doors. However, many cars with rectangular-windowed doors have been refitted with 1st batch trains' doors; car 1162 was the last car with rectangular-windowed doors until its retirement in July 2016. As a result, only trains with square-windowed doors remain.

Batch 1

The first batch of 2nd generation trains consisted of train 1-42~1-63. The cars were manufactured from 1986 to 1991. As built, trains 1-42~1-49 were ten cars long, trains 1-50~1-56 were six cars long and ran on the Ansan Line, and trains 1-57~1-63 were four cars long and ran on the Yongsan-Seongbuk shuttle line.

As ridership increased on Line 1, trains 1-50~1-53 and 1-57~1-63 were lengthened with third generation cars from 1994 to 1997. As this rearrangement occurred, trains 1-50~1-53 and 1-59~1-61 were lengthened to ten cars, and trains 1-57~1-58 and 1-62~1-63 were lengthened to six cars for Ansan Line service.

In 1999, three unpowered cars (two from train 1-42 and one from train 1-43) were rebuilt into driving cars by Daewoo Heavy Industries. They were renumbered to cars 1082, 1182, and 1087 (former trailer car 1842, 1942, and 1943 respectively),[3] and were linked with 1st generation cars. Because no car numbered 1187 was built, car 1087 ran with 3rd generation car 1186 and was retired in 2001.[4] Meanwhile, 1082 and 1182 lasted until 2006, when they were pulled from service due to structural integrity issues, stored at the Byeongjeom Car Depot until the end of 2011, and then scrapped.

All but three trains were overhauled between 2007 and 2008 (see below). Trains 1-53, 1-57, and 1-63 were prematurely retired in 2006, because they were coupled with eight aging 1st generation cars each, so it was found to be easier to retire the trains instead of overhauling them to be fire-resistant. They were stored at the Byeongjeom and Guro train depots and taken off property before the end of 2015.

On May 1, 2010, train 1-58 was wrecked in a collision with Class 311000 train 311-74 (which was known as Class 5000 train 5-75 at the time of the collision). Car 1158 suffered significant damage while other cars behind it received minor damage.[5] The whole trains was retired and most cars were immediately scrapped.[6]

The overhauled trains were replaced by the Class 311000 trains. They were retired between 2012 and 2015. 3rd generation cars built in 1996 that were used to extend the trains were retained for use in other trains.

Batch 2

The first batch of 2nd generation trains consisted of train 1-64~1-73. The cars were manufactured from 1991 to 1992. As built, trains 1-67~1-73 were ten cars long and trains 1-64~1-66 were six cars long and ran on the Ansan Line.

All but one train were overhauled between 2007 and 2008 (see below). Trains 1-63 were prematurely retired in 2006, because it was coupled with eight aging 1st generation cars, so it was found to be easier to retire the train instead of overhauling it to be fire-resistant. It was stored around the system before being taken off property in 2011 or 2012.

The overhauled trains were replaced by the Class 311000 trains. They were retired between 2015 and March 30, 2017, when the last train, train 1-73, made its final run.

After retirement, trains 1-72 and 1-73 were used on the Yeongdong Line for testing in mid-2017, before being towed back and ultimately taken off property for scrapping.

Third Generation

3rd batch train 1-83 leaving Singil Station

Trains 1-74~1-81 and 1-83~1-86 are 3rd batch trains and were introduced from 1994 to 1997, before the Class 311000 (former Class 5000) EMUs were introduced but after the 1st generation Class 341000 and 351000 (former Class 2030) EMUs were introduced. The 3rd batch trains were introduced mainly to supply more trains to Line 1.

The 3rd batch trains also allowed older trains to be extended; aside from the newly-built trains, many additional cars were built in 1996 to lengthen 2nd batch trains from 4 to 6 cars, or 6 to 10 cars (namely, trains 1-50~1-53 and 1-57~1-63). The expansion cars are numbered 1457-1463, 1557-1563, 1650-1653/1659-1661, 1750-1753/1759-1761, 1850-1853/1859-1861, 1950-1953/1959-1961, and 1482/1582. These cars can be found in trains 1-74, 1-81, and 1-83~1-86, and were also coupled to 2nd batch driving cars.

The trains share a similar front end design with the Class 341000 and 351000 trains (as their front ends were derived from those trains' designs), but are otherwise identical to the other Class 1000 trainsets. Therefore, they only operate with other Class 1000 cars. All of the 3rd batch trains were delivered in the old Korean National Railroad (KNR) livery but they have received new livery following overhaul.

The 3rd batch trains are all based from the Guro train depot. Currently, all of train 1-74 sans the driving cars (made excessive when 2nd batch train 1-62 was retired) and the non-driving cars last found in 2nd batch trains 1-61 and 1-64 are retired.

Refurbishments

  • In 1986, the 1st batch cars' air conditioning secondary power device was upgraded from a motor generator to stationary inverters (SIV). These inverters were replaced by new IGBT inverters in 2004 for cars that were overhauled. The air conditioner itself was changed from piston-based systems to screw-motor-based systems.
  • In 1988, the 1st batch cars were retrofitted with air conditioning.
  • In 2000, station notifier systems were installed in the 2nd batch trains to allow train operators to know which stations to stop at during express train runs.
  • The Daegu subway fire compelled Korail to introduce flame-resistant interiors for passenger safety. As a result, from 2004, the 2nd batch trains (except 1-53, 1-57, 1-63, and 1-65) and 3rd batch trains were overhauled with fire-retardant interiors. SLS overhauled some of the 1st batch cars, most of the 2nd batch trains and a few 3rd batch cars. Meanwhile, Rowin overhauled 2nd batch trains 1-62, 1-64, and all other 3rd batch cars. The original Mylar roll film front destination signs, side destination signs, and run number indicators were replaced with LED displays (trains 1-42~1-48 received LCD run number indicators). All trains received the new Korail livery.
  • In 2006, trains 1-47~1-49 received newer Korail EMU doors. Additionally, trains 1-45, 1-50~1-56, 1-61, and 1-71 received 1st batch train doors. Many remaining trains are receiving 1st batch train doors as their original doors fail in operation.
  • In 2011, all trains from train 1-59 had their speakers rebuilt or replaced to allow for clearer announcements.

Preservation

After retirement, a handful of Class 1000 cars were either preserved or repurposed into facilities such as restaurants and pension trains. As of 2015, many 1st batch and 2nd batch cars have been preserved.

1st batch car 1106, which was used as a local restaurant in Incheon until 2015.
2nd batch car 1065 at the old Gudun Station, now used as a training car.

Preserved 1st batch cars include (though not limited to):

  • 1001, 1115 (pictured) and 1315, used as exhibits at the Korean Railroad Museum in Uiwang. Car 1001 is part of the first EMU (from Japan). Meanwhile, cars 1115 and 1315 are part of the first Korean EMU, but when the cars were just preserved, they were renumbered to 1001 and 1301, conflicting with the true 1001.
  • 1107, used as a "pension" car in Hongcheon, Gangwon-do.[7]
  • 1019 and 1119, spotted in Sangju-si, Gyeongsangbuk-do.[8]
  • 1514 and 1134 (and potentially other cars), used as exhibits in the Haneol Theme Museum in Yeoju.
  • Refurbished car 1091 (renumbered from 1832) at Buljeong station on the former Mungyeong Line, used as a "pension train."[9]
  • Two cars with unknown numbers, used as a part of a local facility in Seongnam-si near the Galma Tunnel.[10]
  • A car with an unknown number, used as a part of a local restaurant in Gimje-si, Jeollabuk-do.[11]

Cars 1106 (pictured) and 1109, used as a part of a local restaurant in Nonhyeon-dong, Incheon,[12] and car 1032 was used as a part of a local restaurant in Dong-gu, Daejeon. All 3 cars were sold and are now possibly scrapped.[13]

Preserved 2nd batch cars include:

  • 1065 (pictured) and 1165 at the old Gudun station on the old Jungang Line alignment, used as simulation and training cars.
  • 1771 and 1171, used as training cars at Kyungbuk College in Yeongju-si, North Gyeongsang Province.[14][15]
