Ferrocarril de Antofagasta a Bolivia

Narrow gauge railway line in Chile

The Ferrocarril de Antofagasta a Bolivia is a private railway operating in the northern provinces of Chile. It is notable in that it was one of the earliest railways built to 2 ft 6 in narrow gauge, with a route that climbed from sea level to over 4,500 m (14,764 ft), while handling goods traffic totaling near 2 million tons per annum. It proved that a railway with such a narrow gauge could do the work of a standard gauge railway, and influenced the construction of other railways such as the Estrada de Ferro Oeste de Minas. It was later converted to 1,000 mm metre gauge, and still operates today.
