• Automatic Mapping of the Railway (AMR)

• Summary


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.’

Asset Management Context

• This is an application of DIKW pyramid &

includes the impact of technology

• It promotes data

handling systems

to shift human

thinking effort

up the pyramid


Asset Management Context


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



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


Location/positioning is key to the management and maintenance

Operational Maintenance

Major Projects

• Cross Rail

• GWML Electrification

• Olympics

• High Speed 2

• ERTMS

• Inspection

• Planning

• Whole Life Cycle Costs

• Train Based Monitoring

• Remote Monitoring

• Timetabling

• Signalling

• Level Crossings

• Cable Theft

Video Surveys



• Intuitive track and asset information from systems can be focused to support the wider Asset Management process and business outcomes

• System now exist that are evolving to support AM Systems including associated tasks and activities on many levels



Track Examination Process

Track/Asset Management

Data Collection

Evaluate data & information

Collate information

Analysis

Communicate

Asset intervention


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


Data Collection • Network Rail’s New

Measurement Train

• Vehicles with combined monitoring, and surveying systems on board

• Multi purpose vehicle

• OmniRTPS is used with all the NR

infrastructure monitoring fleet with cameras also fitted to specific vehicles


Data Collection

• HD video and positional data collection using OmniSurveyor3D

• Spatially calibrated for additional information

• Laser Analysis – LiDAR (Light Detection And Ranging) integrated with OmniSurveyor3D


Data Collection

• OmniVision system fitted to underside of the vehicle


Evaluate Data & Information

• Evaluation at source onboard the data collection vehicle

• Ensure quality

• Collate in preparation for analysis


Analysis - Inspections • Quality video data is moving inspection and analysis of the

track away from the danger zone with an auditable process

OmniInspector Kiosk for end user analysis


Analysis – Automatic Inspections • OmniVision is a Plain Line Pattern Recognition system

• Automated analysis of defects


Analysis - Surveying • OmniSurveyor3D - precision hardware for the data collection

• Further analysis of assets can collect position data within the software for export into other systems or viewing platforms

• Creates a consistent auditable method of asset data capture


Analysis - Surveying • Measurements can be taken from point to point

within the software


Analysis - Surveying • LiDAR measurements offer greater accuracy with

envelope contact analysis shown below


Analysis - Design • Inserted virtual objects in the video react as real

• The signal sighting tools allow the task to be reviewed with precision and repeatedly

Analysis – Design

• The Intelligent Scheme Plan(ISP) data exchange

• Creates useable data for the signalling design teams


Analysis – Accurate Mapping • Accurate consistent data referencing

• Other systems can use and visualise complex datasets


Analysis – DIFCAM • Digital Imaging for Condition Asset Monitoring


Communicate • With data accessibility increasing the ability to

communicate complex datasets is becoming easier


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
