The story
Founded by Government of Argentina in 2005.1
The UGOFE was established as an S.A., or limited liability company, on January 7, 2005 through a consortium formed by Ferrovías, Metrovías and Trenes de Buenos Aires (the companies operating the urban services in Buenos Aires Province) with the purpose of taking over the San Martín line until the Government of Argentina gave it in concession to a private company.
The salaries of UGOFE employees were paid by the Government through the Ferrocarril Belgrano S.A., a freight rail company that had been separated from Ferrocarriles Argentinos. On May 22, 2007, when the Government revoked the contract to operate the Roca and Belgrano Sur lines, the UGOFE took over those lines temporarily on June 7 that year.
On May 24, 2012, the contract with TBA to operate the Mitre and Sarmiento lines was revoked after the Once station rail disaster. Both lines were temporarily operated by a consortium formed by Ferrovías and Metrovías, being TBA excluded from UGOFE a few days later.
On February 12, 2014, the Government of Argentina announced that some companies would take over the lines operated by UGOFE. The consortium was officially dissolved.
