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.
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 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.
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
- Trains 331-01~331-13 and 331-23~331-27, in an eight-car TC-M-M'-T-T-M-M'-TC formation.
- Trains 331-14~331-22, in a four-car TC-M'-M'-TC formation.
The symbols are defined below.
- M' car: Pantograph, main transformer, controller, motor
- M car: Motor, controller
- TC car: Secondary power device, air compressor, battery, cabin
- T car: trailer (unpowered)
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)
Depot
The Class 331000 trains are stored at the Munsan train depot, which is a few kilometers south of Munsan station.
