“Using Communication-Based Train Control to Improve
the Efficiency of Metro Railway Operations”
Transportation Systems
In the Beginning …
1
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.

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

Transportation Systems
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

Transportation Systems
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.
