Ferrovías S.A.C. is a privately owned company which, on 1 April 1994, took over the concession, granted by the Argentine government as part of railway privatisation during the presidency of Carlos Menem, for the operation of the 1,000 mm (3 ft 3 ⅜ in) metre gauge Belgrano Norte Line commuter rail service in Buenos Aires, Argentina. Ferrovias also forms part of the consortium UGOFE which operates other commuter rail services in Buenos Aires.
Since 2004 the company also forms part of UGOFE, a consortium with Metrovías and Trenes de Buenos Aires, which took over the running of commuter rail services on the 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.
Since 14 July 2007 Ferrovías has operated the Puerto Madero Tramway in the Puerto Madero district of Buenos Aires.
