• DAY 1: CBTC background & Principles

  

• • Why CBTC?

  • • Risks to be avoided
    • Classic signaling: Principles – Route management – Space between trains – Train Detection – Signals
    • Recurring issues: Space between trains – Maintenance costs – Operation flexibility
  • How CBTC works: Principles - Architecture & Configuration Data - Fixed block & Moving block
  • System operational background: Signaling - Rolling Stock - Operators and man-machine interface - Traction logics - Platform-track interface protection device
  • Grades of Automation (GoA 1, 2, 3 & 4) - Degraded modes of operation procedures

  • CBTC functionalities

  • • Zone controller
    • Movement Authority Limits (MAL)
    • Train location & Energy consumption
    • Door opening/closing
    • Signaling

• DAY 2: CBTC Safety/Security challenges

  
• • Potential Risks
  • Safety Integrity Levels (SIL)
  • SIL 4 and its implications: Standards & Development Process

  • SIL4 Complexity Management

  • • Asynchronism
    • Loss of communications
    • Data transmission: Vital & non-vital
    • Examples of SIL4 typical problems
  • CBTC System examples: CBTC metro lines & Providers (Alstom, Siemens)
  • Operators’ strategies: Interchangeability /Interoperability or “Turnkey CBTC”- Examples of Paris Metro (RATP) & New York City Transit
