France tram lines currently under construction. Active extensions, new streetcar routes and tram network expansion projects.
France tram and streetcar lines currently under active construction: new lines in cities without an existing network, extensions to serve new residential or commercial areas, and reinstatement of previously abandoned tram routes. Many cities are expanding tram networks as part of sustainable transport strategies — this map shows where that investment is physically taking shape. Data from local OpenStreetMap contributors reflects construction works visible on the ground.
France currently has 531 railway segments under construction including 179 railway, 232 tram, 114 metro, 5 light rail and 1 narrow gauge.
