France: The National French Railway Society (SNCF) is planning to use mobile mapping solution to map its rail network. The project is aimed at geo-referencing of railway infrastructure, detecting natural obstacles and determining infrastructural limits for special load transportation.
SNCF will use a 3D data-processing software solution which is a fully integrated and high speed mobile laser scanning system, including a lifting frame for crane installation. The scanning platform can either be installed onto a mounting rack in the rear of a wagon or right into the engine cart. The system allows a surveying train to pass between two regularly scheduled trains without causing delays. It is capable of doing track and base terrain inspection, as well as supervision and registration of changes in train station structures, such as thresholds between platform and wagon due to renovation works in train stations. SNCF has chosen RIEGL VMX-450-RAIL mobile mapping solution with technet-rail”s SiRailScan specialized software for this project.
