Here is an interesting find – graphs comparing the reductions in travel time to cities across France, thanks to the introduction of the TGV (Train à Grande Vitesse) high-speed rail network.

Travel times in 1957.
And fifty years later in 2007.
The graphs were created by Anne-Aël Durand and Gary Dagorn using data from the SNCF’s Open Data platform, and were published in the Les Décodeurs section of French newspaper Le Monde as “Comment le TGV a rétréci la France” (How the TGV has shrunk France).
