Tenda line
The Tenda line or Cuneo-Ventimiglia line, also called in, is a cross-border railway line in the Alpine regions of France and Italy, connecting the Maritime and Ligurian Alps. The line is long, including an tunnel under the Col de Tende mountain pass.
The line connects Cuneo and Ventimiglia, both stations in Italy, but it passes through territory now belonging to France. This historical peculiarity is due to the fact that at the time of its design and construction, the route was located entirely within the Kingdom of Sardinia.
