1 S.F. MUNI’s CBTC System A Brave New World Presentation by Patricia G. DeVlieg APTA Rail Transit Conference June 14, 2000 St. Louis, Missouri

2 u Project Thumbnail Description u Implementation issues u Progress on project objectives u Hindsight TOPICS:

3 MUNI Metro Service Territory EXISTING SUBWAY Embarcadero to West Portal: 5.5 mi Sunset Tunnel: 0.8 mi NEW SUBWAY Embarcadero to Ferry Portal: 0.5 mi NEW INTERLOCKINGS MMT Castro Crossover Green Rail Yard CalTrain Depot Giants’ New Ballpark MUNI Metro Extension (MMX) Embarcadero Montgomery Powell Civic Center Van Ness Church Castro Forest Hill West Portal Sunset Tunnel Duboce Portal Golden Gate Park City College S.F. State Univ. Zoo BART ATCS Territory Surface Rail MKJLN Ferry Portal N Oakland Castro Crossover MUNI Metro Turnback (MMT)

4 Why did San Francisco MUNI embark on this project?

5 Project Objectives u Obtain Optimum Throughput u Improve Safety u Increase reliability & availability, reduce maintenance u Provide inherently flexible operation u Provide fully automated control of new track areas u Enhance passenger information systems, and improve right-of-way intrusion security PRIMARYSECONDARY

6 Basic Project Deliverables u Replace old Signal System on 6.3 mi of dual track, 3 dual portals u Signal new subway extension to waterfront & “Ferry” portal u Replace & enhance central control signal & scheduling systems u Retrofit 59 Boeing SLRVs for ATCS u Equip 77 Breda LRV2s for ATCS u Provide enhanced system performance u Interface with existing systems (SLRV, Wayside interlockings, PA, etc) u Provide design, installation, test, verification & commissioning u Supply training, documentation, spare parts, warranties & DTE u Install & Cutover system without impacting revenue service

7 Phased Service Introduction u LRV2 Interim Cab Signaling (existing system) ä December 10, 1996 u ATCS Operation: all ATP functions, most ATO/ATS w ATCS Shuttle Service on MMX/MMT Extension only ä Jan 10, 1998 w ATCS in existing subway (MMX shuttle continues) ä 1st train June 13, 1998 (weekends only) w Integrated Operation of existing subway & MMT/MMX ä August 22, 1998 ä 2-week demo at 35 tph passed October 14, 1998 u ATCS Full Functionality (Substantial Completion) ä Final Software Release: June 2000 ä 2-week demo at 48 tph: July 2000 ä Reliability/Availability/Maintainability Demos: Summer, Fall 2000 We are here

8 How did the implementation go?

9 ATCS Shuttle Service Area SF Giants

10 So far so good…. Now let’s integrate ATCS with the MMX extension into the existing subway…..

11 The Melt- down August 24 1998

12 September 2: After tense meetings in the Mayor’s office, ATCS was given one chance to perform: To eliminate unequipped trains (non-retrofit Boeings) from the system, running “pure” ATCS.

15 What went wrong?

16 Simultaneous system & service changes New Train Control System + 1st use of new subway extension & turnback + New service on “N-Line” out the new Portal + 1st day of “Proof-of-Payment” fare system + Elimination of “Reverse Riders” = Classic System Engineering Problem

17 Flawed Outreach to Patrons u Massive passenger confusion u Few PR personnel at problem platforms u Absence of Passenger “incentives” Train Control System Problems u Inadequate dual-mode throughput u High incidence of failed non-communicating trains u Design & Spec deficiencies: e.g.: stopping points & door-open scenarios u Passenger Information bugs

18 Is this an exceptionally exotic project?

19 Comparable Projects

20 Project Estimates, then & now Start date August 31, 1992 u Completion: Aug 31, 1995 (3 yrs)est March, 2001(8.5 yrs) u Alcatel Contract (with options exercised) $48.7M$50.8M u Consultant Contracts (Safety $0.4M+Engr $2.4M=) $ 2.8 ($4.37M + $12.5M =) $16.87 u MUNI support Budget$ 4.96$ 9.93 u Tax$ 2.7$ 2.3 u Contingency$ 5.27$ 0 u Total Project Budget$68.43M $79.9M u Scope changes: w restructured fleet make-up w 2nd generation Central Control w enhanced “dual-mode” signaling w multiple functional enhancements w phased implementation OriginalCurrent

21 Where is the project today? Is the project meeting its objectives? Is the system a “better mousetrap”?

22 Project Objectives u Obtain Optimum Throughput u Improve Safety u Increase reliability & availability, reduce maintenance u Provide inherently flexible operation u Provide fully automated control of new track areas u Enhance passenger information systems, and improve right-of-way intrusion security PRIMARYSECONDARY

25 Project Objectives u Obtain Optimum Throughput u Improve Safety u Increase reliability & availability, reduce maintenance u Provide inherently flexible operation u Provide fully automated control of new track areas u Enhance passenger information systems, and improve right-of-way intrusion security PRIMARYSECONDARY

26 SAFETY u Automatically enforced safe train separation u Automatically enforced speed control u Centralized Control w train speed control w “go-slow” zones enforcement w Station & train holds w etc u Detailed performance logs u Emergency Brake Applications u Non-Communicating Trains u Lingering ATCS-Vehicle interface problems KUDOSISSUES

27 Project Objectives u Obtain Optimum Throughput u Improve Safety u Increase reliability & availability, reduce maintenance u Provide inherently flexible operation u Provide fully automated control of new track areas u Enhance passenger information systems, and improve right-of-way intrusion security PRIMARYSECONDARY

35 It’s Great! Much better than the old system ! Julio Says:

39 At Door Open Next 6 trains in subway displayed & Next 3 announced on PA Train Arrival Message:

40 In the right direction….. Where are we headed?

41 Why was it so hard?

42 Anticipated Issues u SYSTEM BOUNDARY PROBLEMS w Open loop (mixed street & subway operations) ä Failed entries & Non-Communicating Trains ä Schedule adherence w Interface Control ä SLRV retrofit, LRV2 interface design ä Public Address system, etc. w Dual Mode (simultaneous old & new signal systems) ä ATCS control of existing block system & signals u STAFFING w Central Control skill set & training w Maintenance skill set & training u PROPRIETARY TECHNOLOGY

43 Issues Less Well Anticipated u ORGANIZATIONAL w “Cultural” shift & resistance to change w Ambivalent Management support w Heavy dependence on Consultants w Intensive Training requirements u SPECIFICATION & PROJECT INITIATION LIMITATIONS w Software requirements & development cycle w Testing Requirements; extended night subway shutdown w Inadequate budget for support staff & contingency w Unrealistic project schedule

44 Maintenance issues u Major shift in technology u Difficulties diagnosing trouble “to the interface” u Configuration Management burden greatly increased u Increased importance of PMs u Training, training, training

45 Next Steps w Acceptance of Final Software Release w 48-TPH Demonstration w Reliability, Availability, Maintainability Demos w Final Deliverables (Manuals, Source Code, etc) w Claims resolution w Contract Closeout: target Spring 2001 w Final Cutover

46 Is CBTC/ATCS a better mousetrap?

47 Judge for yourself…... …..at the APTA Annual meeting San Francisco, September 24-28, 2000 This presentation will be posted at TSD.ORG
