7 UK Rail Statistics In 2014, 3% of trips and 10% of passenger-kilometres were made by rail, 57% of these trips were for commuting or business Franchised passenger operators provided for 62.4 billion passenger-kilometres Rail has a large share of the large regional market in London and South East England and of longer-distance trips to and from London Source: - Transportation Statistics Great Britain: 2015

9 Why is Digitalisation, Visualisation & Intelligence so Important? Increase efficiency of new and legacy systems Build around a connected information network Deliver data in an intelligent and visually meaningful way All stakeholders use the same data sets to make informed decisions

10 How Do You Efficiently Digitise Your Rail Network? Surveying provides important elements for a reliable and efficient transport infrastructure: Comprehensive infrastructure asset management and as-built capture Reliable quality control in the construction process Knowledge of the condition and requirements of the rail network

11 Applications

12 As-built & GIS Documentation Reality Capture GIS & Asset Mapping As-is documentation As-built Management Feature Extraction Best Fit Geometry Corridor Mapping Operations & Maintenance Load measurement Track Geometry Clearances Platform Gauging Tunnel Condition Bridge Inspection Track Profiles Ballast Condition Change Detection Damage Documentation Evacuation Route Planning Slope Montoring Infrastructure Monitoring Monitoring & Incident Response Machine Control Surveying & Stake Out Progress Reporting Reality Capture New Construction Documentation As-built Best Fit Geometry Engineering & New Construction

13 3D Capture Technology Leica SiTrack:One SiTrack:One delivers survey-grade 3D point clouds of the entire rail infrastructure surface without the need to receive GNSS signals for position information. On and off the tracks Simple batch extraction software Easy handling of large amounts of data Work above or below ground

14 3D Capture Technology Leica Pegasus:Two Vehicle-independent mobile mapping solution captures data at speeds of up to 100 km/h. Clearances Asset / GIS / PTC Mapping Track Geometry Change Detection Catenary Mapping Vegetation Mapping

15 3D Processing Software Leica SiRail Suite Batch extraction of clearances, catenary, rail geometry, tunnel assessment, asset mapping, ballast profiles, asset mapping, etc. SiRailScan, allows for a complete extraction of the railway network with engineering accuracy level SiRailManager, database management tool creates a holistic view of an operator s railway network from point cloud to geometry and signal layers.

16 Load Measurement Leica SafeLoad Accurate high-wide load measurements are critical for the safe transport of freights. Loads can be measured from the ground Eliminates hazards associated with climbing on the load and ladders Reduces errors from measuring with manual tools Minimizes clearance related collision potential with high-accuracy laser measurements

17 Sub-surface Mapping IDS SRS SafeRailSystem Fast and non-destructive solution enables you to autonomously inspect railway ballast for renewal and maintenance. Continuous mapping of ballast thickness; Locates areas with insufficient bearing capacity (e.g. ballast pockets); Differentiates between clean and fouled ballast; Detects sections with drainage problems; Identification of undertrack conditions down to a depth of 3 metres and over.

18 Slope Monitoring IDS IBIS-FL Interferometric radar technology for 2D monitoring of displacements and movements in slopes and structures. Helps identify areas of risk for landslide prevention and mitigation projects Provides a complete and real time stability analysis of a slope Monitors remotely without need to place equipment in areas of risk Reduces the time taken to characterise a landsides

19 Case Studies

20 Gotthard Base Tunnel Grunder Ingenieure AG was contracted to deliver a complete inventory and as-built documentation of the Gotthard Base Tunnel without disrupting the ongoing construction. Total of 152 km tunnel track and almost 50 km of new built outdoor track to be surveyed High-definition scans necessary for most accurate representation of the rail geometry Database of 3D imagery and point clouds covering rails, signage, posts, electrical lines, and further structural elements

21 Monitoring Paddington Station Paddingtion Crossrail Station was planned in Construction was taking place directly beneath historic landmarks and the centre of London. The digging could potentially cause structures to tilt or severely crack 42 to 49 total stations monitored over 1,800 prisms on near buildings Collected 8,500 measurements per day Data was processed and analysed with Leica GeoMoS

22 Brighton Mainline Upgrade Topographical surveys required for complex and extremely busy piece of London s railway infrastructure. Avoid costly downtime during expensive and time restrictive track possession Accurate data realisation with Leica Captivate Primary and secondary control using Leica Viva GS14 GNSS Smart Antenna Live RTK data from HxGN SmartNet 3D visualisation of the survey data

23 Olmata Tunnel Olmata tunnel is located along Italy s oldest railway connection between Rome and Naples. The rail network provided (RFI) needed to determine what makes train travel safer within the given historical and environmental context. Aquatic groundwater causes significant hydrogeological problems The tunnel s geometry and status was unknown Combined laser scanners, georadar and thermal cameras for documentation to collect information about the coating status, ballast condition & 3D point cloud

24 Improving China s HSR By 2020, China s high-speed rail and subway network will be more than 30,000 km long. Tracks, rails, tunnels and structures need to be constructed, adjusted, checked and rebuilt. Survey-grade data of rail line, gauge, clearance is captured at 3 5 mm accuracy to create as-built drawings for future planning & design SiTrack:One brought dramatic reduction of night work using several devices on tripods New acquision of 4,000 m per night increased efficiency by %

25 Berlin Metro Mapping above and below ground infrastructure to build an accurate 3D map of one of Berlin s metro station for scenario modelling, viewshed analysis and evacuation route planning. Analysis of existing underground emergency evacuation scenarios Planning of new evacuation routes Kettling plan for maximum crowd control and minimum riot damage View shed analysis for optimal surveillance
