LGV Sud-Est
The decision to build the line is politically motivated by fostering European integration, serving the European institutions in Strasbourg, and geographical balance of French high-speed rail lines, following the construction of high-speed lines from Paris to the southeast (LGV Sud-Est, LGV Rhône-Alpes, &amp; LGV Méditerranée), the southwest (LGV Atlantique), and north (LGV Nord).
