In 1948 the railway network of Argentina was nationalised by President Juan Domingo Perón. The previously privately owned French and British railway companies, together with a number of companies that had been nationalised earlier, (Córdoba Central Railway, 1939, and others), were formed into the following six state-owned companies:
Two years later, the UEPFP (later "Ferrobaires") was established by the Buenos Aires Province Government in order to run long-distance services that had been previously closed by the National Government.[2]
Nevertheless, some temporary consortiums (such as UGOFE and UGOMS) were formed after the contracts of some TBA and Metropolitanoprivate companies were revoked for failing to fulfill their obligations.
Today, the main state-owned railway company is the new Ferrocarriles Argentinos and its subsidiaries, while other companies like Ferrobaires are owned by local provincial governments.
