Railway infrastructure design, construction, and maintenance

We create a highly accurate, information-rich model of your railway infrastructure, delivered to your desktop 24/7. Translating your challenges into Geo-data requirements to provide long term support throughout the life cycle of an asset.

Design: The increasing complexity of infrastructure projects requires a fully integrated solution. Our track and asset information are complemented by geotechnical, ground investigation, environmental and surveying services to empower engineers and consultants to design better.

Maintenance: What information is available to support running assets as efficiently as possible whilst maintaining high performance? With RILA surveys multiple information becomes available, including changes in track centre line, relative track geometry, rail wear, and height and stagger of overhead line equipment (OLE).   

Upgrade: How can you improve railway utilisation while staying on budget and maintaining ageing assets? Track condition assessment, gauging data, and other surveys provide engineering-accuracy Geo-data on the rail corridor, so you can understand the challenges and develop the best possible solutions. Also, our data can be used for (design) tamping and fully automating the process from survey to tamping.

Compact and easily transportable, RILA® connects to a regular passenger train in less than two minutes. From here, it surveys the rail tracks at line speed minimising access costs and reducing carbon emissions with no disruption to services.

Our RILA® train-mounted measurement system incorporates positional sensors, lidar scanners and video cameras to simultaneously acquire point cloud data, live video footage and imagery of the track and surrounding environment. Multiple survey aspects of rail related asset performance and position are recorded to create a high absolute accuracy, dynamic view of the railway corridor.

• Gauging clearance distances along the tracks, platform and structure gauging, but also identification of the overhead contact systems to ensure trains can pass safely and maintain the accepted safety distance to comply with national regulations. Maintenance data to assess the condition of your assets and ensure their reliability and lifespan; for example, track condition and geometry to ensure smooth and safe running trains and ballast profiles allow tamping machines to operate more efficiently and accurately to correct any defects

• Identification of the overhead line equipment (OLE), extracting information from the lidar data on the location of the catenary masts, contact and catenary wires, return conductor and line feeder. Even accurate height and stagger measurements are feasible using our data.

• A clear understanding of ground conditions to supplement track condition data and enable targeted intervention. Site investigations to establish the nature, extent and cause of subsurface problems including drainage, vibrations and material issues. Structural data for bridges, tunnels and trackside infrastructure to investigate problems or defects and extend the lifecycle of assets.

2D and 3D rail asset data is collected within a 3D model of the railway corridor or track twin accessible via a secure web portal. The 3D model replaces one-off, manual surveys with continually updated digital track data, to help engineers understand the environment around an asset. With our portal, users can perform visual inspections and download datasets, customised to their needs.
