Industry and the railway sector are at present entering a new era. Increasingly, the systems in operation today use electronic components instead of relay technique and the railway sector now has the opportunity to improve current systems. However when new technology is installed into old infrastructure, new knowledge has to be taken into consideration. The new technology which is to be integrated into old systems or which is to be applied when building systems from scratch should meet the requirements for electromagnetic compatibility to fit into the infrastructure. To see whether there are any problems in this area, an investigation has been performed based on the failure reporting system used by Banverket (Swedish Rail Administration). Visual inspection has been carried out in the signal and detector boxes located close to the track. Measurements on site have been conducted to follow up the investigation into the failure reporting system and the visual inspections.
