Metrovías S.A. is an Argentine privately held company that operates the Metropolitan services of the Urquiza Line.

[4][5] Metrovías was also operator of the Buenos Aires Underground from 1995 to December 2021, when "Emova Movilidad S.A." took over the concession of the service for 12 years.

[6] On 1 January 1994, Metrovías 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.

Formerly it had a total of 108 stations, 72.9 kilometres of track, with 692 carriages that transport 283.8 million passengers per year, when Metrovías had the Urquiza and Underground concessions.

[9][10] In December 2021, a new company, "Emova Movilidad S.A." (formed by Metrovías and the Roggio Group) took over the concession of the Buenos Aires Underground, for a period of 12 years.
