PROBLEM TO BE SOLVED: To prevent a door from automatically opening after arriving a next station even if a crew turns on a door opening SW while being traveling before the arrival to the next station in a door closing circuit of a train vehicle. SOLUTION: When the vehicle is in a specified point range in a platform at 5 km/hour or lower, a relay DPR is turned on, and when the door opening SW 16 is turned on under this state, a relay DOR is turned on, a lifting up contact 21 is closed, and power is fed to a door closing loading circuit 7, and the door is opened. When the door opening SW 16 is turned on under a state that the DPR is being off (not under a specified point range stopped state), the DSR is being on, the DSR dropping contact 28 is opened, the DOR is being off, and the door is not opened. Also, the DSR lifting up contact 29 is closed, the DSR is self-retained, and then, a specified point range stopped state is presented, and even if the DPR is turned on, the door is not opened resulting from the opening of the DSR dropping contact 28. When the door opening SW 16 is turned off, the self-retaining of the DSR is released, and when the door opening SW 16 is turned on again under the specified point range stopped state, the door is opened.
