Commuter rail in the city is mostly operated by the state-owned Trenes Argentinos, though the Urquiza Line and Belgrano Norte Line are operated by private companies Metrovías and Ferrovías respectively. All services had been operated by Ferrocarriles Argentinos until the company's privatization in 1993, and were then operated by a series of private companies until the lines were put back under state control following a series of high-profile accidents.
