Phase 1

Just to name a few

• 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.
