Map showing French urban railway networks by mode and size. A black dot represents a metro network, a brown one a VAL one. A blue dot represents a tramway network, and a green one another mode of railway urban transport. A simple circle represents a network not existing yet as of March 2008, but under construction or under project. 
The area of the dots show the length of the network in km. The area of the circles representing projected networks do not show length of the projected network.
