Solving Problems of Railway Safety and Maintenance with Laser Scanning Systems


When using 3D imaging, it can be tempting to solve a technical problem with the most advanced scanning system available. But high density point clouds aren’t always the best solution for clients. Take, for example, the use of laser scanning in railway safety.

Railways require preventative diagnostic assessments to ensure that erosion or other environmental changes haven’t made the tracks unsafe. The structure gauges, distance between tracks, track bed stability, and ballast bed profile must be measured for the entire length of a track. Such a task requires rapid data gathering, rapid analysis, and a quick response.

In this whitepaper, Alexander Bakhrakh, of the company INFOTRANS, explains several approaches to railway infrastructure diagnostics. Through these examples, he shows which scanning technology best fits the range of problems found on railways, and why strategic scanning, along with smart processing methods, can create efficient diagnostics without relying on expensive scanners to create high-density point clouds.
