Abstract
A first on-board device installed on a first train controls an emergency brake unit. When it is determined that an actual deceleration value is insufficient in comparison with a predetermined emergency brake reference deceleration value, the first on-board device predicts a first stop location based on the actual deceleration value, and sends, to a ground control device, a first signal indicating insufficient deceleration and a first stop location signal representing the first stop location predicted. The ground control device sends the first signal and the first stop location signal to a second on-board device of a second train traveling ahead of the first train. The second on-board device invalidates a preset first run curve, over a range from a second train location representing an on-track location of the second train to a stop limit location of the second train, and generates a second run curve to control the second train.
