Automatic Train Control (ATC)
ATS
Optimizes Train Schedule
Automatic Train Supervision (ATS)
Monitors train location & speed
Ensures proper headway (distance) between trains
Optimizes schedules for efficiency
ATS monitors the overall train system, including location, speed, and schedule adherence. It can adjust ATO commands or provide information to the driver (if applicable) to optimize train flow.
ATP
Enforces Safe Train Operation
Automatic Train Protection (ATP)
Prevents accidents by.
Enforcing speed limits
Stopping at red signals
Preventing unauthorized movement
ATP receives data from trackside signals and ATO to enforce speed limits and prevent accidents.
ATO
Monitors & Controls Train Movement
Automatic Train Operation (ATO)
Drives the train automatically
Starts, stops,- maintains speed
Opens/closes train doors (optional)
ATO automates train operation, but ATP ensures safety by overriding ATO commands if necessary (e.g., preventing excessive speed).
ATC acts as the umbrella system, encompassing ATO, ATP, and ATS.
