Korail Class 351000

The Korail Class 351000 trains, formerly identified as Korail Class 2000 trains, are commuter electric multiple units in South Korea used on Suin-Bundang Line. Class 351000 trains were manufactured and delivered between 1993.

The Class 351000 cars are arranged in 6-car trains. Details of the car types of each train are listed below:

3510XX (ex-20XX) - Tc (trailer driving car with SIV, air compressor, and battery)
3511XX (ex-22XX) - M (motor car with inverter and controller)
3512XX (ex-23XX) - M' (motor car with pantograph, transformer, inverter, and controller)
3513XX (ex-24XX) - T (trailer car)
3514XX (ex-25XX) - M'
3519XX (ex-21XX) - Tc

Trains 351-09, 351-11~351-12, 351-14, 351-17~351-18, and 351-20~351-28 use Toshiba GTO-based VVVF controls with active cooling, while all other trains use IGBT controls with passive cooling through a heat pipe. The trains are equipped with regenerative braking, reducing energy consumption and simplifying train inspection. The trains feature a more powerful air conditioning system than that on the Class 1000 trains.

The 1st and 2nd generation Class 351000 trains used an ivory-colored interior with a long sheet prior to their overhauls. All 1st and 2nd generation trains, as well as subsequent generation, use a white interior. LED display monitors are installed on the top of each car. The end cars have a space for wheelchairs.

The Class 351000 trains equipped with TGIS use color displays, and service machines can be automatically controlled in TGIS after a refurbishment of these trains in 2005. Dead section notifiers are also installed.

Most of the Class 351000 trains are stored at the Bundang Depot, which is located between Jukjeon Station and Bojeong Station. The remaining other Class 351000 trains are stored at the Siheung Depot, which is located between Oido Station and Darwol Station.

The first generation of Class 351000 trains were built from 1993 to 1999 by Daewoo Heavy Industries and Hanjin Heavy Industries. Because of the flat front ends, the trains are nicknamed "flat face" (납작이).
