Unidad de Gestión Operativa Ferroviaria de Emergencia (UGOFE) was a temporary consortium of Argentine companies formed on 7 January 2005 by Ferrovías, Metrovías and Trenes de Buenos Aires to take over the running of commuter railway services in Buenos Aires after concessions granted to Metropolitano in 1994 for the operation of these services were revoked.

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 Belgrano Norte Line commuter rail service in Buenos Aires, Argentina.
