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.
