300 Km/h on the Eurostar, Picture 2, France, 2012

Here it's easier to tell we're in France. The large number of tracks is the giveaway, as well as the land even flatter than Belgium. Other than on the Shinkansen system, there aren't any other networks that I can think of as well suited to highballing as the post-1990 SNCF LGV system.
