In August 2019, the operator CarPostal (acquired by Keolis, but DSP subsequently won by Transdev: launch January 2022) decided to trust Padam Mobility to provide its solution for the DRT Libellule network. Four lines (1 zonal line and 3 virtual lines) serve the Villefranche-sur-Saône train station from the outskirts ofurban area.
The RésaLib A line allows users to travel to all the stops on the line at the time he or she wishes and without constraint. The RésaLib B, E and F lines are virtual lines that serve the entire urban area. They are operated according to established itineraries and theoretical schedules.
