General Mitre Railway from Retiro to the cities of Rosario, Santa Fe, and points between, in northern Argentina. Including all its commuter and long-distance services, the company ran approximately 1,000 trains per day and carried about 147.7 million passengers annually, or 500,000 daily. From 2004 the company also formed part of Unidad de Gestión Operativa Ferroviaria de Emergencia (UGOFE), a consortium with railway companies Metrovías and Ferrovías, which took over the running of commuter rail services on Belgrano Sur, Roca and San Martín lines in Buenos Aires after concessions granted to Metropolitano S.A. for the operation of these services were revoked. Revocation of concession Following a commuter train accident on 22 February 2012, at Once Station, Buenos Aires, in which 51 people died and at least 703 people were injured, TBA was placed under federal intervention on 28 February. Its concessions to operate the Mitre and Sarmiento lines were revoked on 24 May. After the cancellation of the contact, both lines were taken over by the consortium Unidad de Gestión Operativa Mitre Sarmiento (UGOMS) and later Trenes Argentinos, putting them back in state hands. In October 2015, an exposé in the conservative daily newspaper La Nación highlighted the firm's apparent mismanagement while in charge of the commuter rail lines. The article revealed large expenditures by the private company on luxury items including jewellery and champagne, as well as trips to Doha and Dubai. At the same time, the company was still under investigation into the Once Tragedy and still had AR$ 70 million worth of unpaid fines as a result of its business practices. It was also revealed that the company had bribed the former transport minister Ricardo Jaime, who was also under investigation. Sergio Cigliano, one of the owners of TBA, was convicted and sentenced to nine years in prison for negligence surrounding the original accident which had resulted in the revocation of concession.
