Metrovías S.A. is a privately owned company which, on 1 January 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 standard gauge Urquiza Line commuter rail service in Buenos Aires, Argentina. This service had previously been run by the state-owned Ferrocarril General Urquiza since nationalisation of the railways in 1948. In addition Metrovías took over the management of the Buenos Aires Metro system when it was privatised in 1994. In 2004 the company became part of the consortium UGOFE which operates other commuter rail services in Buenos Aires.
Urquiza Line operating from Federico Lacroze Terminal to General Lemos and the Metro together have a total of 108 stations, 72.9 kilometres of track, with 692 wagons that transport 283.8 million passengers per year. The company has approximately 3,000 employees.
Since 2004 the company also forms part of UGOFE, a consortium with Trenes de Buenos Aires and Ferrovías, which took over the running of commuter rail services on Belgrano Sur Line, Roca Line and San Martín Line in Buenos Aires after concessions granted to Metropolitano S.A. for the operation of these services were revoked.
