DESCRIPTION
Presentation 5 of 8 from Horizon 2020 for Rail event held 8th Nov 2013. The calls for research being made under the rail heading in the surface transport work programme for 2014 - Intelligent Infrastructure - and who to contact for further information. • Intelligent Infrastructure (cost-effective infrastructure; planning tools for infrastructure projects; intelligent traffic management systems; energy management)

The UK mainline railway • 20,000 miles of track • 1,000 signal boxes • 9,000 level crossings • 40,000 bridges and tunnels • 2,500 stations (all but 17 leased) • Much is over 150 years old • 37,000 people in NR – maybe 100,000 in whole industry? • Another 20% improvement in efficiency over CP5

Opportunity 1 Moving from ‘Find and Fix’ to ‘Predict and Prevent’
• How to?
– Extensive remote condition monitoring – Embedded ‘sensoring’ – Measurement trains – Unattended measurement from Service Trains
• Data consolidation and evaluation – Do we need to monitor everything? Can we predict from a %
of devices measured and predict? • Asset Degradation/Prediction tools

Opportunity 2 Maintaining traffic around a possession
• The ‘tyranny’ of the replacement bus service
• Most of the railway does not have bidirectional signalling and key switch auto lock outs – taking possession takes too long!
• Can’t (as yet) put up ‘Murphy’s traffic lights!
• Limited amount of points on the railway
• Could we roll out a flat packed rolled up point on top of the existing track
• Simple cheap diversionary piece of track?
• Other ways of getting around a worksite???

Opportunity 3 - Mechatronic S & C? • Line speed switches and crossing? • Inherently fail-safe locking philosophy’s using technology and machine
science already in use in other sectors (e.g. Aerospace etc). • Adaptive sensing and monitoring philosophy for
– Automatic self adjustment – Asset monitoring. – Effective asset management
• Safety checks (FPL) extended to 48 or even 96 weeks? • Removes activity from the track so increases track worker safety • Weather resilient designed in • Lighthouse to Shift2Rail?

Opportunity 4 - New Rail Design
• Opportunity to rethink rail design and metallurgy • If the rules of conicity have changed we can rethink rail and wheel
profiles • Do we need inclined rail? Embedded rail? • New rail steels must reduce and lower the carbon footprint, and take
resilience to fatigue to a new level – Self healing and lubricating rail steel (nanotechnologies) – Multi-use rail surfaces (as per old bull head ) to reduce carbon
demand • Lighthouse to Shift2Rail?

Opportunity 5 - New track support system
• Low Installation
• Quick – 24hrs
• Unreliable Geometry
• Tamping – reducing life
• Ballast 20 years
• Sleeper 60 years
Ballast
• High Installation • New build • Good Geometry • Issue – fixing & fastening • Sub grade • Life good
Slab
Benefits: • Construction • Material • Simple • Climate • Carbon
Take good features from above
KPIs: • noise • system cost • availability • maintenance

Opportunity 6 - Substructure
• Bulk material of cuttings and embankments strengthened by designed piling, core strengthening, water resilience • Tree and vegetation management complimentary to the environment and substructure strength • All work conducted whilst railway is still in traffic:
Top layer reprocessed to provide; • consistent a stable support to the track support system • Water proofing • Reprocessed in situ
Track support
