PURPOSE:To simplify the equipment by providing an ATC ground element for generating a point signal by adding a set position signal to an ATC signal, and by operating an ATC controller and an ATO controller via the ATC ground element for receiving the signal of said ATC ground element. CONSTITUTION:From the ATC ground element 15 of a transponder type, a point signal 16 including a set position signal for generating the output of the set position information of the ground element, added to an ATC signal for specifying stop or speed limit, is generated. By a transponder onboard element 17, the point signal 16 is picked up, and is transmitted to an ATC controller 19 and an ATO controller 20 via a transponder receiver 18. By the ATO controller 20, the exact present running position of a train is detected through the set position signal among the point signals 16, and acceleration is controlled so that a train speed 13 may coincide with a desired speed pattern 14. In this manner, the number of ground equipments and onboard equipments is reduced. |
