The Gran Chaco is known as the “Green Hell” for its extreme weather conditions.
The word "chaco" comes from the indigenous Quechua language and means “hunting land”.
The Gran Chaco covers approximately 650,000km²; an area larger than France.
The railway enabled the growth of Chaco province by one million people over 150 years.
A new regeneration plan will upgrade 1,600km of Chaco railway track between 2011 and 2015.
Cotton and cattle are Chaco’s main products, though sugar, sunflowers and sorgum are also produced.
