  • The target speed and braking profile curve between stations are calculated based on the line speed restrictions and grade conditions indicated by the ATP.
  • The braking commands are then calculated to match the target speed and braking profile, so that the train stops at the specified station-stop position.
  • The target settings can be programmed to adjust automatically in response to actual conditions through communication with the line side operating management system; this can be used to help counter delays or, conversely, to initiate energy-efficient driving when ahead of schedule.
  • The ATO System is also compatible with platform-gate interlocking control as well as driverless automatic starting and automatic resetting of equipment-fault indications, using a highly reliable system for the communication of safety information.
