Revolutionizing Rail: How Signaling Tech Powers Faster, Greener Trains

The PEO Algonquin Chapter is pleased to invite members to an engaging technical presentation. Join rail engineering expert Orijit Pandit for a fascinating exploration of the evolution of railway signaling—from vintage mechanical arms to today’s AI-powered smart systems. Discover:

• The basics of electrified rail's 2×25 kV AC systems used in bullet trains around the world
• How wireless signaling (CBTC) enables self-optimizing schedules during rush hours
• Real-world solutions reducing maintenance costs
• The future of driverless rail using 5G and predictive AI

In this session, Orijit will explain:  

1. The Power Behind Speed: Caltrain's Electrification Revolution  

• 2×25 kV systems explained: How transmitting power at 50 kV then stepping down to 25 kV minimizes energy loss across 51 miles  
• High-speed rail tech on commuter lines: Shared infrastructure enabling future 110-mph Caltrain/HSR blended service 
• Field challenges: Retrofitting legacy corridors while maintaining daily service   

2. The Evolution of Signaling: Where Safety Meets Smart Technology  

• From mechanical arms (1800s) to modern CBTC and AI-powered collision prediction systems 
• How CBTC wireless networks replace trackside hardware  

 3. Integration Breakthroughs

• Unified control centers managing signaling, power, and passenger flow 
• Predictive maintenance slashing costs through SCADA-CBTC synergy  

 4. What's Next for North American Rail 

• Self-adjusting timetables using live passenger data 
• Future CBTC Expansion Projects such as NYC MTA
• Future 2x25 AC electrification projects
• Next-Gen CBTC Innovations
