Fabien Verdier, mayor of the small sub-prefectural town, dreams of saving the minutes to reach the capital. He would like a prioritization of the TER over the RER C with a siding, between Dourdan and Brétigny-sur-Orge.

By making this choice, 22 minutes could be saved for commuters between Tours (Indre-et-Loire) and Austerlitz station. Fewer trains on the line could also make it possible to strengthen the connection with an increase in the number of daily return trips.
