• Mandated following Ladbroke Grove
• 100% replica of live railway
• c.150 TREsims now installed
• Safe off-line environment for;
• Training & assessment
• Response to disruption/emergency
• Operational analysis
• Engineering and maintenance
• Most VDU-based control workstations
• + Accurate model of interlocking
• A fully controlled virtual railway

Why is it needed? • Other sectors use it more vigorously
• Modelling and Decision Support (NR Technical Strategy)
• CP5 volume & efficiency challenges
– Test & refine the end users’ specification – reduce rework
– Efficient design process – reduce rework/human intervention
– Reduce cost
• Systematic use brings many benefits
• Fits with industry initiatives such as;
– ‘Safety in Signalling Projects’
– Assured Project Delivery
– ‘Safe by Design’
• Enhances the NR GRIP Process

• Automate design & testing • Use simulation for principles
checking • Reduce reliance on testers • Free up resource • Safety benefits • Accelerate projects • e.g. TREsure - Interlocking Test Tool
TREsure: Origins/Concept
Questions from RIA
• Can TREsim be used to test for
situations that are difficult to
observe using traditional
techniques – particularly across
interlocking boundaries?
• Can this testing be automated?
12
Network Rail request • To test from entrance into the interlocking under test all the way through
to exit from the interlocking – for all possible route paths
• To test for locking (or absence!) for all moveable infrastructure and
opposing routes at locking level (+ aspects?)

Summary
• Modelling and Simulation a benefit throughout the project life cycle
• Good examples, but more work to do
• Improves the efficiency of the process
– Better specification
– Faster test
– Less rework
– Less live railway access needed
• Reduced cost and programme duration
• Safety can be enhanced
• Early adoption = early benefit!
