EuroCap-Rail
EuroCap-Rail (also spelled Eurocaprail or Eurocap Rail) is a proposed high-speed rail corridor through Belgium, Luxembourg, and France to connect three cities—unofficially considered the capitals of the European Union—which host six of the seven institutions of the European Union: Brussels, Luxembourg, and Strasbourg. The project would upgrade rail lines from Brussels to Luxembourg (city) to Baudrecourt, France and utilize the LGV Est (opened in July 2016) between Baudrecourt and Strasbourg. EuroCap-Rail is a priority project among the Trans-European Transport Networks.
