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.
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.
The Class 331000 trains sport a white-colored, fire-retardant interior. LCD monitor displays are installed on the side of each car for trains 331-01~331-13, and on the top of each car for trains 331-14~331-27. The end cars have a space for wheelchairs.
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.
The Class 331000 trains are organized into two formations
The symbols are defined below.
The cars of each train 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 trains 331-14~331-22 are M' cars) 3315XX - M (inverter) 3316XX - M' (pantograph, transformer, inverter) 3319XX - Tc (SIV, air compressor, battery)
The Class 331000 trains are stored at the Munsan train depot, which is a few kilometers north of Munsan Station.
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).
