The present invention relates to an electric dual-opened plug door system for a track train, and has the structure that a loading driving mechanism is positioned at the upper part of the train body; a door leaf is connected with the loading driving mechanism through a holding door frame; transmission shafts at the two sides of the train door are connected with the small hanger of the loading driving mechanism through flaps, and then arranged at the two sides of the train body after being connected with a locking device at the middle-lower part of the train door; a roller in a lower swing arm device is arranged in a lower lead rail at the lower part of the train door; an external operational device and an emergency operational device which is arranged at the inner side of the train body are connected with the locking device through steel cables; the lock rail of the door leaves is arranged to match the lock hook on the locking device; the present invention has the advantages that the multi-class locking device strengthens the safety and the reliability of the train door system; through adopting the square lead rail and the slide block loading mechanism, as well as the cross coordinate working manner formed by square lead rails and short lead pillars, the structure of the loading device is compact and the loading capability is improved, and the installation, adjusting and maintenance of the loading device are easy and convenient. The present invention meets the demands of the high speed, safety, reliability, sealing, and sound and heat insulation for the door system of the intercity railway transportation.
