PURPOSE: An automatic train stop apparatus using combined three, four, five phases is provided to improve the applicability by installing two onboard antennas that generates an electronic induction coupling with a wayside antenna. CONSTITUTION: A wayside equipment(100) is comprised of a wayside antenna(110), a wayside antenna relay(120), and a signal post. An onboard equipment is comprised of an onboard antenna, an oscillator(220), a frequency detector(240), a speed detector(230), a controller(260), a brake(280), and a display controller(250). The onboard antenna is comprised of a first onboard antenna(211) and a second onboard antenna(212). The first onboard antenna(211) is mounted on a lift side of a train to produce an electronic induction coupling with the wayside antenna(110) installed on a left side of a railroad. The second onboard antenna(212) is mounted on a right side of the train to produce an electronic induction coupling with the wayside antenna(110) installed on a right side of the railroad. A switch(290) is electrically coupled between the first and second onboard antennas(211,212) in order to select a signaling manner corresponding to three phase, four phase, or five phase railroad block.
