History
In 2004, Seoul Metro ordered a first batch comprising 5 ten-car trains (2-01~2-05) and 1 four-car unit (2-57) from Hyundai Rotem. The trains were delivered in 2005 and replaced aging 1st generation 2000-series trains.
In 2006, Seoul Metro ordered a second batch comprising 29 ten-car trains (2-15~2-31 and 2-61~2-72) and three four-car trains (2-58~2-60) from Hyundai Rotem.[1] The trains were delivered from 2007 to 2008 and replaced aging 1st generation 2000-series trains. Trains 2-23~2-31 and 2-71~2-72 use newer unpowered 1st generation 2000-series cars built between 1991 and 1992, which were retrofitted with technology found in the newer trains.
In 2015, Seoul Metro ordered a third batch comprising 20 ten-car trains (2-06~2-13, 2-39~2-42, 2-85~2-92) from Dawonsys.[2] The design of the carbody changed somewhat. The trains were delivered from 2017 to 2018 and replaced aging 1st generation 2000-series trains and 2nd batch standardized wide-width trains.
In 2017, Seoul Metro ordered a fourth batch comprising 21 ten-car trains (2-14, 2-32~2-38, 2-73~2-84) and one four-car train (2-56) from Hyundai Rotem.[3] The design of the carbody changed once again, and was revealed in July 2018.[4] The trains were delivered from 2019 to 2020 and replaced aging 1st generation 2000-series trains, rebuilt trains formed from newer 1st generation 2000-series cars, and 2nd batch standardized wide-width trains.
In 2018, Seoul Metro ordered a fifth batch comprising four six-car trains (2-45~2-48) and 22 unpowered non-driving cars was placed with Dawonsys.[5] The design of the carbody is identical to that of the third batch trains. The trains are planned to be delivered in 2021. The six-car trains will replace aging rebuilt trains formed from newer 1st generation 2000-series cars, while the 22 unpowered cars will replace the newer 1st generation 2000-series cars in second batch trains.
