Ferrocarriles Argentinos Sociedad del Estado, more commonly known as Ferrocarriles Argentinos, is a state-owned agency that is responsible for operating all freight and passenger train services in Argentina. The current agency was formed in 2015 after a plan to renationalize all the railroads was announced. The first incarnation of Ferrocarriles Argentinos was founded in 1946 and operated for over 45 years. In 1993, the railroads were privatized. However, economic crises and poor maintenance of infrastructure during this period utlimately led the government to renationalize the railroads. As of 2018, Ferrocarriles Argentinos operates 22,970 miles (36,966 kilometers) of track, making it the 8th largest railway in the world. While this is still quite large, when World War II ended the rail network operated over 29,000 miles (47,000 kilometers) of track.
