. The study presented in this paper deals with the excessive transversal vibrations of the catenary poles located on the Savoureuse viaduct; a railway bridge on high speed line in France. This viaduct across the Savoureuse River opened in 2011 for commercial runs of high speed trains between Dijon and Mulhouse in France. During inspection visits, the maintenance agents on site detected that the catenary poles presented strong transversal vibrations perpendicular to the track axis. RFF and SNCF were then concerned for the integrity of the concrete boxes fastening the catenary poles and the stability of the catenary itself. A full study was carried out by SNCF to explain the phenomenon and to find the best solution to reduce these transversal vibrations.
