Introduction • Why examine the track?
• Recent Rail accidents in one year – Human factors: 39.27% 172 Track defects: 126 28.77%
• Federal Railroad Administration Office of Safety Analysis
• Track examinations were initially done visually
• 1920s saw the introduction of vehicle based monitoring and inspection in the US and France
• With increased speeds and traffic automated technology based track examination is a necessity on many areas of rail networks
• Examining track infrastructure is all about asset information

Asset Management Context • AMC AMBoK - May 2011
– Is specifically concerned with physical assets,
– But notes they are inextricably linked with financial, human, information & data, and intangible asset types
• IAM Asset Management – An Anatomy – Feb 2012 – Refers to ‘Asset Knowledge Enablers’
– With details of Asset Information Strategy, Knowledge Standards, Information Systems, Asset Data Knowledge
• GFMAM – AM Landscape - Mar 2014 – Refers to ‘Asset Information’ as a category
– With details of Asset Information Strategy, Asset Information Standards, Asset Information Systems, Data & Information Management
• BSI PAS 55-1:2008 - Clause 4.4.6 Information Management refers
• ISO55001 – Clause 7.5 Information Requirements refers
– (ISO 27000 series should not be overlooked when reviewing organisation information)

Asset Management Context • Information availability and specification
– Asset Information policy
– Asset Information Strategy
– Asset Information Standards
• To align information systems
requires definition
• Technology will be part of the
solution
• Benefits being line of sight,
informed decisions regarding
asset whole of life

Asset Management Context • Network Rail has embarked on the ORBIS Project
(Offering Rail Better Information Services)
‘ORBIS will establish an information services operation for a
devolved GB rail industry that will deliver the information and
insight required to enhance the effectiveness of the processes
employed to plan, design, change, manage and operate the
railway.
Realisation of the vision and roadmap will further improve safety
for people working on, or using, the railway and will
significantly improve the value for money the railway delivers
in the whole life management of its infrastructure assets.’

Track Knowledge via Examination
• The datum for the physical assets on a rail
network is the track and its location/position
• A single relationally linked model of the network and its assets is fundamental
• Asset Information Systems integration development of applications focused around asset management, asset inspection, asset positioning creates consistent timely asset knowledge
• Development of innovative products aligned with business process will deliver asset information clarity for accurate decision making

Track Knowledge via Examination • UK Network GeoModel
©Copyright 2013 Omnicom Engineering Limited All Rights Reserved 11
Track Knowledge via Examination
The key features of the model are:
• Geographic model of the rail network
• Visualisation of assets and asset information located against the
GeoModel
• Visualisation of pre-recorded or near real time images and video
capture by location
• Underlying imagery and maps
• Visualisation of current vehicle location and operation parameters
• Review of network utilisation and future use(s)
• Serve data to any standard geospatial product i.e. Google
Maps/Earth, ArcGIS, etc
• Serve data to other business process aligned third party systems
• Visual other datasets using location as the reference

Data Collection • Rail defect detection
– Ultrasound - most popular
– Eddy current inspection
– Magnetic Particle
Inspection
– Radiography - used on
specific locations
– Magnetic Induction
or Magnet Flux Leakage -
earliest method used to
locate unseen flaws
– Electromagnetic Acoustic
Transducer
Integrated location increases track asset knowledge

Systems Review • OmniSurveyor3D®
The key features are:
• Easily identify the accurate geographic and linear
position/dimensions of assets.
• Build up a comprehensive geospatial/linear database of assets.
• Export spatially-referenced imagery for use with standard
GIS/Asset management systems.
• Use as a replacement/aid to many different projects that normally
involve access to the track.
• Overlay third party condition data (e.g. track geometry or GPR
information) within the video to provide a visual context to its
network location and surrounding environment.
• Overlay and manipulate virtual objects within the video.
• Undertake signal sighting using built-in signal sighting tool.

Systems Review • OmniVision®
The key features are:
• OmniVision is an automatic inspection system for identifying a
number of defined defects associated with the track and
surrounding infrastructure
• High resolution line scan and area scan images of the track up to
160 Km/h
• Integrates laser measurement, imagery and geometry data
• In addition captures thermal imagery and ballast shoulder
information
• Data is captured on the vehicle and post processed using image
processing algorithms
• Business rules are used to define “candidates” for inspection

Conclusions The benefits of the technologies are:
• Significant reductions in the need for track visits, increasing safety
and reducing costs.
• Efficient deployment of strategic plant and equipment resources.
• Increased rail network safety for employees and contractors.
• Greater knowledge of the network and assets.
• Improved asset and resource utilisation.
• Greater stakeholder engagement, both internal and external.
Structured data, specified information, and dependable
knowledge supports an Asset Management System and
promotes organisational wisdom
