Tucumán Ferrocarriles S.A. (also known for its acronym TUFESA) was a company in Argentina which operated a 1,000 mm (3 ft 3 3⁄8 in) metre gauge railway line between Buenos Aires and Tucumán in Argentina, currently part of Mitre Railway network after nationalisation of the entire railway network in 1948.
As part of a national railway privatisation plan, carried out under the presidency of Carlos Menem, a concession to operate the line was granted to the government of Tucumán Province in 1992, that ran a service named El Tucumano although it did not last so long.
After El Tucumano was definitely cancelled, in 1997 the provincial government called a tender to operate trains to Tucumán. "Tucumán Ferrocarriles S.A." (abbreviated "TUFESA") was granted a concession to run the service. The company started operating in 1997 with an express service with stopped only in intermediate stations La Banda, Colonia Dorá, and Rosario Norte. Some of the diesel locomotives used were EMD GT-22 and Alco RSD-16. Soon after the company launched a standard service with 4 trains per week to Tucumán. 
Some financial problems resulted in the cancellation of the contract of concession in 2000 therefore passenger services were interrupted. Two years later, trains from Buenos Aires to Tucumán would be run by NOA Ferrocarriles S.A., with a service named El Jardín de la República ("Garden of the Republic"), taking about 24 hs to connect both cities.
