The urban and suburban services were operated by transitional company FEMESA until they were given in concession to local private company Trenes de Buenos Aires (TBA), which was widely criticized due to the poor conditions of its services. After the rail disaster of 2012, the government revoked its contract with TBA and the services were taken over by a newly created state-owned company, SOFSE, which later renewed the urban parts of the network with new rolling stock and infrastructure.
