We are developing a Digital ATC system, in which the ground equipment detects train location by using track circuits and transmits digital coded data through track circuits. Transmission items include the track circuit identification number, the number of unblocked sections, and other data required for train operation. The on-board equipment generates a onestep braking profile using an on-board database, the data received through track circuits, and its own position detected by the integration of axle rotation. We have carried out field tests on the Kagoshima line of JR Kyusyu. We verified that the Digital ATC system functions as originally designed.
