Ferrocentral
Ferrocentral was an Argentine private railway company, with a name formed by a combination of the Spanish words for "Central Rail". It operated long-distance passenger trains from its base at Retiro station in Buenos Aires to several locations in northern Argentina, running on Ferrocarril Mitre's 5ft 6" in gauge railway|Indian gauge]] tracks.
The company also ran regional services (such as Tren de las Sierras) on Ferrocarril Belgrano's metre gauge tracks in Córdoba Province. The National Government invested $ 10 million to re-open the line.
