1. Transportation Systems IREE Conference, Delhi, India 26 July 2014 “ Using Communication-Based Train Control to Improve the Efficiency of Metro Railway Operations”

2. Transportation Systems [ref]/[date©Thales 2010 1 In the Beginning …  The SelTrac system concepts and techniques of communication-based Automatic Train Protection are from the LZB system used on mainline railways in Europe.  These concepts were first adapted and proven in service for Urban Rail on the Berlin Line 4 in 1972.  The first unmanned, CBTC train went into service in Vancouver, Canada in 1986.

5. Transportation Systems [ref]/[date©Thales 2010 4 Communications-Based Train Control Key benefits Increased capacity - Allows the safe, close operation of more trains on the same track Energy Safings – Increased automation allows for more precise control of train and ability to trade-off performance and energy usage against the current need of the railway Improved Safety – Automation reduces opportunities for human error. Reduced infrastructure investment Track Circuits Signals

6. Transportation Systems [ref]/[date©Thales 2010 5 Emerging Trends 1.Eliminate ‘fallback’ systems dependent on signals and track circuits or axle counters 2.Invest in ‘interoperable’ solutions. Interoperability Interchangeability Vehicle Interface 3.Evolving Standards IEEE IEC

7. Transportation Systems [ref]/[date©Thales 2010 6 Opportunities for the Indian Market Can an ‘Indian Market’ be created? To what extent can Indian Operators get together to agree on principles? Can operators agree on a specific, expandable, vehicle interface? Is it possible to create an independent certification body with a test track? Fault tolerant vs. Fallback? Making the leap of faith.
