  • START Geographic map overview of Tube Lines assets
  • Example details of a bridge, gives detail of structure and its location, also links to bing map and record photographs
  • Can show live maximo work orders, in this case projects upgrade work.Aids management in long term – can overlay projects onto areas having high number of faults, also can see details of track type in use.In short term allows high fault areas to be seen and targeted.Also can relate faults in different assets, example track ballast faults with failed drainage pipes.Can also be used to show and check track patrol routes correctly cover all track areas.

  • Click to edit Master title style GIS Overview London Underground Jubilee, Northern & Piccadilly Lines AGI Asset Management SIG 06 September 2013 John Woollett GIS Manager Asset Management Improvement Programme London Underground
  • Click to edit Master title style What is the Asset Management Improvement Programme (AMIP)? • Not IT-driven. It is business process-driven., enabled by IT and IM • A programme of works to align Asset Management Systems (AMS) and Enterprise Reposes Planning (ERP) with business processes • Re-defines and enforce new, efficient business processes • Increase visibility of assets and standardize reporting (as all levels) across the business • Embedding Web GIS and plans - ‘spatial reports’ – across the business • Started within Tube Lines , now part of London Underground
  • Click to edit Master title styleAsset maintainer for Jubilee, Northern and Piccadilly Lines Assets shown on GIS : • Track – Linear assets, track work orders ( faults and projects ) • Civils - Bridges & Structures • Civils – Earthstructures • Civils – Deep Tunnels • Civils – Track Drainage • Environmental – Access gates etc. Maximo Work Orders • Track Faults • Track Projects • Scrap Removal
  • Click to edit Master title style Data Requirements - Need to capture track complexity in a Database • Track diagrams don’t always display track complexities. • Representing each piece of rail was not practical and compromises had to be made. • Detailed survey drawings were often not available.
  • Click to edit Master title style Track – Linear assets, track work orders ( faults and projects ) 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
  • Click to edit Master title style • To verify the legacy codes, existing track diagrams were annotated with the track and point (switch) codes. • These are sent out to be verified by the local managers against marker plates that are fixed on to the track. Data Verification and Construction - LRS Code
  • Click to edit Master title styleData Verification and Construction - Building the calibrated LRSThe Track Diagram showing allocated codes LRS of track centreline with point&crossing (switch) areas allocated in GIS Background map © Crown Copyright.

  • Click to edit Master title style Relationship between GIS and Maximo GIS shows assets & work orders etc.. geographically Maximo sits on Oracle database, geometry held in spatial cartridge, asset and work order data geometry Maximo Asset data Work orders Maximo Applications – Work Management & Asset Register Access databases, with asset data (being migrated into Maximo wherever possible)
  • Click to edit Master title style Data Requirements - Storing of track linear assets details in the Database • Discrete assets such as signals and lubricators are held in a table. The signal is plotted on GIS map using the LRS location from the asset record. Selecting the signal in GIS brings up a view of the Oracle record. Maximo entry for a Signal Distance from start of LCS area LCS location and Signal Number
  • Click to edit Master title style Track Assets in Maximo Track linear asset details - rail type, age, ballast , rails joints etc. for one track section held with start and stop positions along the asset.
  • Click to edit Master title style Diagram view of track asset composition – from Maximo Gives a clear representation of the Maximo data
  • Click to edit Master title style Geographic view of track asset composition – from Maximo REPRODUCED FROM THE ORDNANCE SURVEY 1:1250 MAP WITH THE PERMISSION OF THE CONTROLLER OF HER MAJESTY'S STATIONERY OFFICE, CROWN COPYRIGHT, LICENCE No. AL 51128A/0001 2008
  • Click to edit Master title style GIS - MAP OVERVIEW To find a bridge
  • SEE DETAILS OF BRIDGE Go to Bing view of Bridge Select Bridge for details
  • Click to edit Master title style SEE WORK ORDERS FOR A BRIDGE
  • Click to edit Master title style Gates surveyed by fence inspector, with links to photographs and aerial photos . ACCESS GATES
  • Click to edit Master title style Digitized from OS maps, with subsequent amendments . CIVILS : EARTHSTRUCTURES
  • Click to edit Master title style From legacy system (DAMS) Linked to drainage engineers spreadsheet for details and condition. Graphics updated by drainage engineers Link to aerial photos added by GIS CIVILS – TRACK DRAINAGE
  • Click to edit Master title style Civils – Deep Tunnels From Asset Location Plans .
  • Click to edit Master title style 100m track marker positions and kilometrage Property address details ( addresspoint ) . PROPERTY ADDRESSES ( with distance to track)
  • Click to edit Master title style PROJECTS WORK ORDERS FROM MAXIMO Draw circle around place of interest Details of projects from Maximo
  • Click to edit Master title styleBenefits of GIS • Geographical inventory of Assets. Linear assets now plotted by the GIS using location component of Maximo. • Assists with fault and emergency response. • Poor asset condition easily identifiable (spatially/linearly). • Fault and wear trends are analyzed geographically. • Relationship between performance of assets is understood better (i.e. track subsidence related to blocked drainage). • Gives Managers a ‘like live’ view of work in progress • More effective planning of engineering works: - Visualizing the assets in an area allows ‘work packages’ to be scheduled to correct all the faults in the area. - Environmental data information helps to manage environmental impact and constraints
  • Click to edit Master title styleAsset Management GIS Future Plans • Maximo integration (ActiveG) • Planning in new areas? • Mobility? • Asset Inspection Train (uses model) • Further use of CAD / BIM data in GIS • Environment / Fencelines?
