A necessary step ahead for constantly improving efficiency
and optimizing infrastructure and operating costs.

The imajing clever process

The key for cost reduction

Deployable on all types of trains, both compact and stand-alone, our devices are designed for massive and recurrent collection of geo-referenced 3D images of your network.

Data collection integrated into the daily workflow

  • Opportunistic and/or systematic data collection.
  • Time and cost saving thanks to less repetitive field visits.
  • Quick and easy installation: no need for prolonged immobilization of rolling equipment.

Profitable anticipation with ongoing monitoring

  • Comparison over time.
  • Change detection and predictive maintenance.
  • Immediate benefit for users and travelers.
  • Reduced costs related to train breakdowns and immobilization.

Dynamic network assets inventory

  • Equipment targeting
  • Better management and planification of maintenance operations.
  • Precise budget estimation.
  • Significant security improvement.

Increased productivity with shared data at the office and on the field

  • Secured access and immediate data availability online.
  • Pervasive content availability.
  • Locate and access data from a smartphone with imajnet® LRS App on your daily field operations.
  • Unique reference for all.
  • Virtual rail corridor.

This stream of images is then processed within a powerful toolchain in order to generate 3D images and accurately georeference every visible pixel.


The workflow goes through machine learning, which automatically localizes equipment, feeds the GIS database and detects eventual changes.


All data are published online on the web services provided by imajnet® for serving any application that needs to immerse users in situations with added information to virtually interact with reality.

These images can be visualized with synchronized maps and GIS information at any time and any place.

GIS/CAD users can also use it as a production source to fulfill or update field map or drawings.


Finally, to close the loop, field operations teams share the same linear referencing system. That way, they can have access to real time tracking and report events or tag elements through their smartphones to consume them in the virtual railway web service back in the office.

a technologICAL toolchain to permanently keep an eye on your infrastructure.


An accurate track topology nationwide

  • A track by track digital map that reflects the actual infrastructure.
  • Geographically accurate.
  • Naming of each segment.
  • A graph connecting segments.


a precise linear referential

  • A positionning of each kilometric pole or virtual computation of all kilometers.
  • Projected on each track.
  • To localize any equipment in linear coordinates.
  • To be able to compute distances along the track.
  • To have a single and simple reference to localize in the field.


Georeferenced assets inventory

  • Signs, signals, switching point, balise, crocodile, level crossing, station bank, tunnels…
  • Dynamic asset database.
  • ETCS/CBTC compliance.


link to existing data
and documentation

  • Create an equipment database from schematic drawings with linear position by construction.
  • Match asset inventory with the equipment database.
