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.
Cabin
The Class 381000 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.
