What it is

A 1,000 mm gauge line between Mendoza and Los Andes that crossed the cordillera via a summit tunnel at about 3,200 m, with Abt rack sections on the steep grades. It joined the Atlantic and Pacific railway systems from 1910 to 1984.

It was closed in 1984 after avalanches and the destruction of a bridge; there are recovery proposals.

What it led to

  • freight connection between Argentina and Chile across the Cumbre pass
  • a model of rack mountain railway in South America
