SNCF Réseau is deploying innovative solutions in order to take action more quickly on the railway tracks and in the areas along the railway lines. The programme to accelerate the renewal of the railroad switches is based on industrial processes and on the use of new work site equipment. It is now focused on cutting edge technology (e.g. surveillance trains, drones, laser technologies) and on rigorous training programmes for railway staff. These upgraded methods clearly demonstrate that for SNCF Réseau - the Infrastructure Manager – safety is an absolute priority.
