The Turin–Modane railway is the international rail connection from Turin, Italy to Modane, France. It passes through the Susa Valley and the Fréjus Rail Tunnel. Together with the French Culoz–Modane railway it is often called "Fréjus Railway" or "Mont Cenis Railway". A major landslide in August 2023 forced its closure for most likely over one year.
