The Rail system in Paraguay consisted primarily of a 376 km main line of standard gauge between Asunción and Encarnación (with a connection to Posadas, Argentina). The infrastructure was administered by Ferrocarriles del Paraguay S.A. (FE.PA.S.A.), corporation established in 2002.
As of 2006, all traffic has been suspended except weekly tourist steam trains between Jardín Botánico de Asunción (Asunción Botanical Gardens) and the city of Areguá (23 km) plus an additional 15 km section to the village of Ypacaraí under renovation and cross-border freight trains between Posadas in Argentina and Encarnación. As of 2007 steam 2-6-0s built between 1910 and 1914 still perform shunting duties. The former main station in Asunción has been converted into a railway museum.
As of 2010, following the collapse of an abutment of a bridge on the Rio Ytay, the tourist steam train traffic has been suspended until repairs can be effected.
In early 2013, freight traffic was down to one train across the border every few weeks, with shunting mainly handled by Argentine diesels.
In 2010, the rising level of the Yacyretá dam flooded the tracks on the Argentinian side, which halted grain exports by rail from the Encarnacion goods terminal until a new track was completed, at a higher level, in June 2012.
Railways in Paraguay were inaugurated in 1861, during the era of Carlos Antonio López. Privatized and renationalized several times, the railroad was finally nationalized in 1961. As of 1988, the 367-km rail system was outdated, wood-powered, slow and costly even with government subsidies. The volume of cargo carried on the railroad declined in the 1970s and 1980s as alternative roads and waterways became more efficient, though some agricultural goods did move by train. In Encarnación, the Paraguayan railroad system connected via ferry, then since 1990 via the San Roque González de Santa Cruz bimodal road-rail bridge, with the Argentine city of Posadas, which is connected by Ferrocarril General Urquiza to Buenos Aires and the Uruguayan and Brazilian railroad systems. There also was a small "soybean railroad" near the Brazilian border.
