ACSES Positive Train Stop

  • Transponder sets stop point at Home signal
  • PTS enforced if Cab signal not better than restricting
  • Released by radio if the Home Signal not at Stop
  • Train civil speed limit through the interlocking is sent by radio

conclusion
Conclusion
  • In service
    • 75 Mile section - December 10, 2000
    • 22 Mile section - March 26, 2001
  • Provides functionality desired
  • Operators are learning the conservative nature of the brake curves
  • Input from operators is being used to modify system operation
  • ACSES + Cab signal provides civil speed, train separation and signal speed enforcement
