Transandine Railway-2
The central Transandine Railway from Valparaíso, Chile, to Mendoza, Argentina
is defunct, pending reconstruction.
While Chile and large parts of Argentina both use the same 1,676 mm gauge, the connecting Ferrocarril Trasandino Los Andes - Mendoza used a narrow gauge of 1,000 mm (3 ft 3 3⁄8 in) with rack railway sections.
Thus there are two break-of-gauge stations, one at Los Andes, Chile and the other at Mendoza.
In 2009, a deal was signed to build a single gauge base tunnel connecting Chile and Argentina.
South Trans-Andean railway
From Lonquimay (Chile) to Zapala (Argentina) – construction abandoned. 220 km line once again proposed in 2005 and work underway at Chilean end in 2005; first stage completed by early 2006. Possible break-of-gauge and rack railway.
From Osorno to Bariloche – never built.
