Trenes de Buenos Aires (TBA) (In English: Trains of Buenos Aires) was a private company that operated commuter rail services over the broad gauge Sarmiento and Mitre lines of Buenos Aires. The company, owned by Claudio and Mario Cirigliano, also operated long-distance services on the General Mitre Railway to central-western Argentina and on the General Urquiza Railway to northern Argentina and Uruguay on the international Tren de los Pueblos Libres. From 2004 to 2012 TBA, a company which is a subsidiary of the Plaza Group controlled by the Cirigliano family, was part of the consortium Unidad de Gestión Operativa Ferroviaria de Emergencia (UGOFE) which operated other commuter rail services in Buenos Aires. The company became synonymous with the collapse of the railways in Argentina under privatisation and the company was subject to numerous investigations and legal proceedings. History TBA was established in 1995 after the Carlos Menem's administration privatised all the railway network, giving the company a concession to operate the metropolitan Mitre and Sarmiento railway lines by Decree N° 730/95. The company took over both lines on 27 May 1995. During the first two years of the concession, TBA met the requirements specified on the contract, regarding the frequency of the service, with an average of 98%. By February 1999 the consortium had invested US$200 million, which included the reconstruction of 220 Toshiba carriages and the remodelling of 13 stations and workshops. In addition, a new ticket selling system was introduced with the installation of automated counters. One of the most notable improvements was the introduction of "Puma" coaches on the Retiro-Tigre branch. Those coaches had been built by local factory Emprendimientos Ferroviarios S.A. (EMFER) and featured air conditioning, ABS brakes and computer-supervising systems. In 1997 the Government decided to modify the contracts of concession with a plan of modernisation worth US$2.5 billion. The future investments required the acquisition of 492 brand-new electric multiple units, refurbishing of more than 100 km of existing tracks, and the installation of new signalling, among other improvements. Nevertheless, the Government of Fernando De la Rúa (who had come to power in 1999) made changes to the original project, reducing the amount of the budget to US$1.3 billion. As compensation to the companies, the State provided subsidies to TBA and the other private operators. In addition to the commuter rail services on Sarmiento and Mitre Lines, TBA also operated long-distance passenger trains on the
