During the 1930s, it was decided to expand the station via the construction of a new main building. As a result of repeated aerial bombardments of the city during the Second World War, the station suffered extensive damage, including to the recently completed main building. Accordingly, this building would be later rebuilt, albeit in a simplified configuration, during the immediate post-war years. Since the late 1990s, Roma Tiburtina station has been managed by Grandi Stazioni, a wholly owned entity of the Italian state railway operator Ferrovie dello Stato Italiane. While Roma Tiburtina station is regarded as being a heavily trafficked transit hub, even greater passenger numbers have been recorded at the more centrally located Termini.
