The company also ran regional services (such as Tren de las Sierras) on Ferrocarril Belgrano's 1,000 mm (3 ft 3+3⁄8 in) metre gauge tracks in Córdoba Province.[3] All of the train routes managed by Ferrocentral had been previously operated by Ferrocarriles Argentinos, the country's now-defunct national passenger railroad corporation.Ferrocentral was established in 2005, being formed by two railway companies, Nuevo Central Argentino (concessionary of Ferrocarril Mitre's freight services) and Ferrovías (which operates the Belgrano Norte Line) with the purpose of running trains from Retiro station in Buenos Aires to the city of Córdoba.[4][5][6] In 2006 Ferrocentral started to run trains to Tucumán, with stops in Rosario and La Banda, a city of Santiago del Estero Province.[9][10] In addition, some problems with ticket sales were reported by users, accusing the company to give a poor service for online purchasing, as well as the virtually nil availability of seats.
