PROBLEM TO BE SOLVED: To improve riding comfort so as to further aim at energy saving effect in a railway security system. SOLUTION: Such a warning zone calculation means 61 is provided for calculating a warning deceleration pattern which is a running pattern whose speed level is lower than that of a security deceleration pattern, and for recognizing a running state surrounded by the security deceleration pattern and the warning deceleration pattern as a warning zone, in an on-vehicle signal securing device in a railway security system. In addition, such functions are given to a speed checking means 64 that when the own train and an objective deceleration target are approaching to each other, it is judged whether the own train is relatively approaching or not to a warning zone recognized by a warning zone calculating means depending upon the present moving speed of an objective deceleration target relative to the own train's running speed and that when the own train is relatively approaching to the warning zone, an acceleration notch suppressing command is outputted to the driving/braking device 66 of the train. |
