The Korail Class 331000 trains are commuter electric multiple units in South Korea used on the Gyeongui·Jungang Line. Class 331000 trains were manufactured and delivered in 2009 and from 2012 to 2014 to provide service on the Gyeongui Line and to address progressing extensions (starting from the extension to Gongdeok Station.
Technical details
Electrical parts
All trains use IGBT controls and use passive cooling with a heat pipe. The trains are also equipped with regenerative braking, reducing energy consumption and simplifying train inspection, and they use electric door motors.
Interior design
The Class 321000 trains sport a white-colored interior. LCD monitor displays are installed on the side of each car for trainsets 321-01~321-13, and LCD monitor displays are installed on the top of each car for trainsets 321-14~321-27. The end cars have a space for wheelchairs.
Cabin
The Class 331000 trains share the same cabin design with the Class 321000 as many of the cars were derived from Class 331000 trains. Stop notifiers are installed, as are TGIS use color displays. Dead section notifiers are also installed.
Formation
The Class 331000 trains are organized into two formations
- Trainsets 331-01~331-13 and 331-23~331-27, in a TC-M-M'-T-T-M-M'-TC formation.
- Trainsets 331-14~331-22, in a TC-M'-M'-TC formation.
The symbols are defined below.
- M' car: Pantograph, main transformer, controller, motor
- M car: Motor, cotroller
- TC car: Secondary power device, air compressor, battery, cabin
- T car: trailer (unpowered)
The cars of each trainset are numbered to correspond to the type of car each car is: 3310XX - Tc (SIV, air compressor, battery) 3311XX - M (inverter) 3312XX - M' (pantograph, transformer, inverter) 3313XX - T (trailer) 3314XX - T (trailer) (this car on trainsets 331-14~331-22 are M' cars) 3315XX - M (inverter) 3316XX - M' (pantograph, transformer, inverter) 3319XX - Tc (SIV, air compressor, battery)
Depot
The Class 331000 trains are stored at the Munsan train depot, which is a few kilometers north of Munsan Station.
Batches
1st batch
The first batch of Class 331000 trains were introduced in 2009 for the opening of what was known the Gyeongui Line at the time.
The first batch trains are numbered 331-01~331-13. The trains have new, smoother aluminium bodies, but they use the same front end design as the third batch Class 321000 trains. The first batch trains have LCD display monitors on the sides (above the doors).
2nd batch

The second batch of Class 321000 trains were introduced following the Gyeongui·Jungang Line's eastward extensions until Yongsan Station, when the Gyeongui Line became the Gyeongui·Jungang Line.
The second batch trains are numbered 331-14~331-27. The trains have LCD monitor displays are installed on the top of each car. The trains also use the same front end design as the third batch Class 321000 trains, but the exterior body was reverted back to the standard, ribbed type stainless steel body seen on all new cars.
Trainset 331-27 was manufactured and delivered in late 2012 to address the extension from Digital Media City Station to Gongdeok Station. It was originally six cars long, but was lengthened to eight cars in November 2014.
Trainsets 331-14~331-22 were manufactured and delivered in late 2013 to expand the rolling stock on the (at the time) Gyeongui Line. These trainsets are only four cars long and operate on the Seoul Station branch of the Gyeongui·Jungang Line.
Trainsets 331-23~331-26 were manufactured and delivered in late 2014 address the extension from Gongdeok Station to Yongsan Station. These trainsets were delivered with eight cars each.
Derived units
Class 361000 trainsets 361-01~361-13, which use the 1st batch body design, were derived from the Class 331000 trains.
