Location-Aware Rail Asset Management Location-Aware Rail Asset Management Presentation Transcript

  • Location-AwareAsset ManagementSteven EglintonGeospatial Information ManagerTube LinesMarch 2011
  • The Challenge1) “Improve precision of track fault locations”2) “Reduce work bank from identifying duplicate faults”Required criteria for solution:• Enable workforce to resolve to 1m track location• Create consistent & validated inspection data• Ensure output is machine-readable• Provide easy-to-use solution/tool for the above
  • Location – We think in a line• To define where we are on the track – need a coding system ( Legacy system specified by London Underground) • N124 = unique area code • N = northern line • EB = eastbound track • LO = local track • 101 = 101 metres along track in direction from start of an area
  • Mobility• Location Acuracy to +/- 0.3m• > 60% of network is above ground Screenshots from GNSS device
