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.
From 2004 to 2014 the company also formed 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. UGOFE was dissolved in 2013.
Ferrovías operated the Puerto Madero Tramway, in the Puerto Madero district of Buenos Aires, from July 2007 until its closure in October 2012.
Outside of Argentina, the company also operates the Lima Metro in Peru.
