There is no doubt that recent years have seen a significant rise in railway usage for passenger mobility. Railway network operators face increasing pressure to ensure safety and prevent line disruptions that lead to delays. This is especially true for SNCF Réseau, which is responsible for managing and maintaining the French railway infrastructure to ensure the safe operation of passenger services. To support the infrastructure manager, TCP has once again developed a vital
solution: the catenary gauge study survey.
The project focused on Lyon Perrache station, a key hub with over 320 daily train departures and more than 7 million annual passengers. As a vital railway axis on the French network, it is particularly challenging to manage during works that require road closures.
With help of 3D LiDAR technology combined with artificial intelligence, safety can be maintained, and electrical and fire risks prevented during renewal works. A virtual template verifies the necessary safety distances between catenary cables, existing infrastructure, and any pant / machinery deployed on site. This is achieved using a 3D gauge on a point cloud, which automatically detects collision points.
TheCrossProduct specialises in LiDAR railway gauging and clearance studies, offering automated measurements, safety distance assessments, and 3D railway template testing—delivering a precise, rapid analysis.
