By 2013, the rolling stock of Buenos Aires' commuter rail network was ageing and deteriorating rapidly. At the same time, high-profile accidents in Flores and Once in previous years had led the national government to revise the concession-based railway privatisation, which was largely blamed for the deterioration of the network. The government thus decided to intervene, revoking concessions to companies such as Trenes de Buenos Aires and setting up Trenes Argentinos to manage the lines.
