Core Signaling Benefits • Train Spacing • Safety – Total Situational Awareness • Compatibility • Cost • Reliability & Resiliency • Power & Space Constraints • Installation Time Public Benefits by 2020 • Onboard WiFi • Safer efficient advanced cab signaling Public Benefits by 2024 • Safer automated control • Trespasser detection • More frequent service

Other Benefits from CV & Total Situational Awareness Just to name a few Drone Inspection Right-of-way Yard & Non-revenue and Maintenance Worker protection Equipment tracking Phase 1 Precision asset Public Onboard WiFi Trespasser Detection management and tracking

Challenges and Costs • Challenges • Dealing with signaling vendors – minimal in Phase 1 only • Dealing with train car vendors – minimal in Phase 2 only • Vital safety certification of new technology • Costs • Phase 1 - $100M - $200M – Communications deployment and Cab signaling • Phase 2 - $100M - $200M – Full CBTC deployment • Compare to $20 billion cost for current CBTC technologies • Low life cycle maintenance costs Biggest saving comes with easy installation in existing lighting during normal maintenance cycles. No major track outages for in track work and wiring.
