The Korail Class 371000 trains are commuter electric multiple units in South Korea used on the Gyeonggang Line.

Technical details[edit]

Electrical parts[edit]

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[edit]

Cabin[edit]

The Class 371000 trains share the same cabin design with the 2016 batch 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[edit]

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[edit]

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

Trains[edit]

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.
