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.
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.
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:
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.
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):
An eight-car formation was as following (where YY is one integer greater than XX, and ZZ is one integer greater than YY):
Trains 1-01~1-41 were 1st batch trains and were introduced from 1974 to 1977. Their general appearance was similar to Japanese EMUs built around their time; in fact, trains 1-01~1-14 were assembled by various Japanese companies. However, trains 1-15~1-41 were built by Korean companies including Daewoo Heavy Industries under license. As a result, train 1-15 is nicknamed "The First Korean EMU". All of the 1st batch trains were based at Guro train depot and had the old Korean National Railroad (KNR) livery up to their retirement. The Seoul Metro Series 1000 trains are identical to these trains, and other Seoul Metro trains share similar designs with these trains.
