The development of the tram-train concept inspired plans to reinvigorate the "ligne des Coquetiers" using this system that seemed ideal. It solved the problems caused by the rail crossings by transforming them into simple road junctions. It reduced disruptions in the urban landscape and expanded the use of trams in urban transportation all while greatly increasing service. This technology was finally adopted, and in 2001 the SNCF called for European tenders for the trains and cars. In 2003 the draft was approved by the STIF, SNCF, and RFF.
