    • Intelligent Maintenance Andy Doherty Date 05.11.13 1
    • 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 Date 05.11.13 2
    • Forth Rail Bridge Date 05.11.13 3
    • Manual labour! Date 05.11.13 4
    • Overhead Line Measurement Systems . Date 05.11.13 5
    • Asset Information Coordinated Through EDC Systems Information Flow Wheel condition Customers Operators Video survey Gauging Conductor rail Ground Radar EDC 12/11/2013Official Course Title as per Standard/OLM/Lesson Plan – Issue x.x Date 05.11.13 Enhancements Ultrasonics Track geometry Rail profiles Video Inspection Overhead Line Radio Survey Maintenance 6
    • 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 Date 05.11.13 7
    • Predictive Modelling tools for Asset Management  V M, Iyy Sensors for remote condition monitoring to be embedded into the whole track system m, Iyy CONTACT M, Ixx m, Iyy CONTACT CONTACT CONTACT Rail Rail Rail Rail Sleeper + Ballast Sleeper + Ballast Sleeper + Ballast Sleeper + Ballast OHL Ex© m, Ixx CONTACT Wire/Pan degradation Prediction Model CONTACT Rail Rail Sleeper + Ballast Y Ground X Z Y Ground X Ground Z Fatigue resistant rails that are low carbon but have multi-use surfaces Under-sleeper pad: Wheel Rail degradation model that predicts maximum track capability with real time output to control system Energy recover capability Increased ballast life New ballast specification that requires no tamping to maintain geometry Risk reduced Ballast Ex© Degradation Prediction Model Improved Stiffness function Improved VTISM &Stiffness function climate change resistant Bridge EX© Degradation Prediction Model Date 05.11.13 8
    • 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??? Date 05.11.13 9
    • 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? Date 05.11.13 10
    • 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? Date 05.11.13 11
    • Opportunity 5 - New track support system Ballast Slab •  High Installation •  Low Installation •  Quick – 24hrs •  New build þ •  Good Geometry •  Unreliable Geometry þ •  Issue – fixing & •  Tamping – reducing life fastening •  Ballast 20 years •  Sleeper 60 years Benefits: •  Construction •  Material •  Simple •  Climate •  Carbon Date 05.11.13 þ •  Sub grade Under sleeper support New track support system Take good features from above •  Life good þ KPIs: •  noise •  system cost •  availability •  maintenance 12
    • 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: Date 05.11.13 Track support Top layer reprocessed to provide; •  consistent a stable support to the track support system • Water proofing • Reprocessed in situ 13
