The Korail Class 371000 trains are commuter electric multiple units in South Korea used on the Gyeonggang Line. They were built alongside the Korail Class 381000 trains, which are identical trains that are used on the Donghae Line.

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.

All trains use LED headlights. There is a third headlight in the same compartment that houses the train run number and destination sign.

Interior design

Cabin

The Class 371000 trains share the same cabin design with the 2016 bath of the 3rd generation Class 311000 trains (trains 311-95~311-99). Stop notifiers are installed, as are TGIS color displays. Dead section notifiers are also installed.

Formation

The Class 371000 trains are organized in the following formation: TC-M'-M'-TC

The symbols are defined below.

M' car: Pantograph, main transformer, controller, motor
TC car: Secondary power device, air compressor, battery, cabin

The cars of each train are numbered to correspond to the type of car each car is: 3710XX - Tc (SIV, air compressor, battery) 3711XX - M' (pantograph, transformer, inverter) 3712XX - M' (pantograph, transformer, inverter) 3719XX - Tc (SIV, air compressor, battery)

Depot

The Class 371000 trains are stored at the Bubal train depot.

Trains

The Class 371000 trains are numbered 371-01~371-12. Delivery of the trains began on February 19, 2016 and continued until August 19, 2016.
