The train control device is disclosed. By using a camera for recognizing a track surrounding geographic features in AR recognition camera recognizes a unit train around geographic features. The location detection server unit receives the first recognition information through the AR recognition camera compared with the second information stored in the database and calculates a first position of the train. Phase control is calculated are compared to recreate the exact location of the third position of the train to the second position of the calculated train information through a predetermined method on the first position information and the on-board subsystems of the received train from the location detection server unit transmitting a third location above the ground the control server, and controls the train receives a moving section, which allows the train to move from the ground control server received. Phase radio transceiver unit may phase the control unit is transmitting or receiving information with ground control server. According to the invention, by controlling the train by using the augmented reality that can identify the location of a train by recognizing the surrounding terrain and surrounding-equipped detecting the train position to minimize the ground equipment to increase the availability and to lower the maintenance cost . In addition, if an extension or a new line of train line without any additional installation of auxiliary ground facilities to detect the position of the train, only changes to the database to recognize the surrounding geographic features of the onboard equipment to the onboard equipment performs the position detection of trains so.
