  1. May 2001 Amtrak Advanced Civil Speed Enforcement PTC System Status Report Jim Hoelscher

  2. ACSES CBTC Conference 2001

  3. ACSES PTC Overview • Advanced Civil Speed Enforcement System • Northeast Corridor • 240 Route Mi./ 506 Track Mi. • Plan 400 route miles/ 1150 Track miles • 48 Interlockings • Plan ~ 100 interlockings CBTC Conference 2001

  4. ACSES PTC Overview • 460 Locomotives & Commuter Trains • AEM 7, F40PH2, GP40, GP9, U23B, B23-7, GP 38, GE Super 7, MP 15, F40 • Kawasaki, MBB, & Bombardier Control Coaches • High Speed Locomotives • ACELA High Speed Tilt Trains CBTC Conference 2001

  5. ACSES PTC Overview • Overlays the Cab Signal System • Independent of Cab Signal • Cab Signal Provides Speed Limit for Safe Train Separation and Signal Speed Enforcement • ACSES Provides Civil (Track) Speed Limit and Positive Train Stop at Interlocking Home signals CBTC Conference 2001

  6. Advanced Display Unit ACSES Vital on-board Computer Transponder Reader and CTV box Axle generator Trainborne Equipment Radio Antenna CBTC Conference 2001

  7. ADU Signal Aspect Cab Signal Speed Limit Enforcement Indicator Civil Speed Limit CBTC Conference 2001

  8. Transponders Transponder data contained in Programmable plug • Operates to 310 MPH • Passive - No wiring CBTC Conference 2001

  9. ACSES PTC Overview • Transponder Operation • On board antenna transmits 27.115 MHz signal • Wayside transponder receives signal + Uses energy in received signal to power transmitter • Transponder transmits 4.5 MHz data signal • Message contains 255 bits - 180 bits data, 72 bits CRC + 3 fill bits CBTC Conference 2001

  10. ACSES PTC Overview • Transponder Data • Location of Transponder (RR, Line, MP, Track,) • Distance to Next Transponder • Current Civil Speed for 5 Train Types • Distance to Speed Restriction • Speed Restriction Speed Limit For 5 Train Types • Length of Speed Restriction CBTC Conference 2001

  11. ACSES PTC Overview • Transponder Data (Cont.) • Distance to Home Signal • Grade • Local ATCS Radio Address and Frequency • Phase/Power Break Start/Stop Locations CBTC Conference 2001

  12. ACSES PTC Overview • ATCS 200 Radio Network Data • Interlocking Home Signal Status • Interlocking Exit Track • Start/Stop Location of Temporary Speed Restriction • Temporary Speed Limits for Passenger and Freight CBTC Conference 2001

  13. 100 mph 80 mph 60 mph ACSES Speed Restrictions Curves, Bridges, etc. CBTC Conference 2001

  14. Target Speed = 0 DS HS Radio Vital Encoder 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 CBTC Conference 2001

  15. ACSES PTC • Phase I • Civil Speed Enforcement • Home Signal Stop Enforcement (PTS) • Phase II • Radio Release PTS • Temporary Speed Restriction - On Board Enforcement CBTC Conference 2001

  16. ACSES PTC Phase I Status Boston R. I. / Mass. 190.8 Cove 228.0 Conn./ R.I. 141.1 Junction 214.0 New Haven High Street 139.0 Nan 113.3 In Service Dates May, 2001 May, 2001 December 10, 2000 May, 2001 Mill River 73.8 CBTC Conference 2001

  17. ACSES PTC Phase I Status NJ/NYC 1.2 Pa./N.J. 57.7 Maryland/Delaware 41.4 Ham 55.5 Holmes 77.2 County 32.8 Delaware/Pa. 18.2 Morris 58.3 Washington, D.C. Ragan 29.7 Maryland Prince 57.3 131.6 Grove 112.4 In Service Dates June 30, 2001 Not Scheduled March 26, 2001 Landover 128.8 CBTC Conference 2001

  18. ACSES PTC Phase I Status • On-board equipment installed & ready for (or in) service (241 Units) • 77 Amtrak • 74 MBTA • 24 CSX • 16 P & W • 14 CDOT • 12 High Speed Locomotives • 24 Acela CBTC Conference 2001

  19. ACSES PTC Implementation • Standard Interfaces designed to allow application of ACSES on different locomotives and control cars • Cab Signals Systems • Air Brake Interface • Locomotive Controls CBTC Conference 2001

  20. ACSES PTC Phase I Operation • Infrastructure Data Must be Accurate • Curve Speeds & Locations • Chaining data • Operation Problems • No problems with transponders • Operator’s learning curve • Brake Curves conservative • No Time to Penalty or Brake curve information given to operator CBTC Conference 2001

  21. ACSES PTC Phase I Operation • System Modifications • Expand wheel size calibration range • Redefine actions requiring operator acknowledgement • Modify Tilt Enable/Disable • Energize ACSES magnet valve when cutout CBTC Conference 2001

  22. ACSES PTC Phase II 2oo3 Safety server TSR server Network server - 1 To CETC Network server - 2 HUB 1 HUB 2 NMS WCC / FPD 1 WCC / FPD 2 1 of 10 1 of 10 Multiplexer Multiplexer Multiplexer Multiplexer 1 of 4/5 1 of 4/5 DSU DSU DSU DSU A/B switch Modem DSP 9600 BCP Modem Modem Encoder Encoder Train MCP

  23. ACSES PTC Phase II Operation • Temporary speed restrictions (TSR) by CETC operators • Current process retained • Paper copies and/or voice radio updates • TSRs transmitted to trains in terms of radio coverage areas • Train receives all TSRs in direction of travel for current plus next 2 radio coverage areas • TSRs enforced by onboard equipment the same as permanent speed restrictions received from transponders CBTC Conference 2001

  24. ACSES PTC Phase II Status • BCPs delivered • Antenna sites being determined • Encoders delivered • Site specific logic design started • TSR Input Process & Interface with CETC operators defined • Office servers and communications network designed • OBC requirements defined CBTC Conference 2001

  25. ACSES PTC Phase II Schedule • Phased implementation • PTS Radio release • TSR enforcement • To be completed 2002 CBTC Conference 2001

  26. PTC Interoperability • NJT ASES • Equipment • Compatible transponders • Standard antenna/transponder interface • System • Transponder messages defined by Amtrak/NJT CBTC Conference 2001

  27. 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 CBTC Conference 2001
