No smoking in the EMU, smoking will trigger smoke alarm, causing emergency parking on the middle of the train. The following is my personal reasoning, welcome to add!
Smoking in the EMU train will trigger the smoke alarm, causing the train deceleration or emergency stop, causing delays across the board, at the same time because the EMU train speed, the closed environment, if fire consequences be unbearable to contemplate.
Because of this, the high speed train speed, full closed operation, to prevent fire hazard and fire early, the more than a fault sensor and a smoke alarm installation of EMU, run on the way, if there is any part in the car smoking passengers would trigger a smoke alarm, which leads to slow down or even automatic train emergency stop, seriously affect the safe operation of trains.
