During the course of the ETCS Corridor A major project, DB Netz AG needed updated planning documents in order to plan the equipping of sections with the ETCS train control system based on these documents. SIGNON supported the customer in validating the existing PT1 as-completed drawing documents in the first two sections of European Corridor A (six control areas in total) as well as reproducing the safety-related site plan for one of the most important hubs in the Ruhrgebiet (Ruhr area).
Measured data generated using the SATengine mobile mapping system were used as the basis for updating and reproducing these documents. The lines were inspected using SATengine, then the equipment elements were surveyed and compared to the respective positions in the as-completed drawings. The aim here was to verify the existing positions and identify any deviations. During the course of this work, the data only available previously on the plans were digitised for the next stages of planning.
