The new trains will be used on the 22.2km Line B, and on Line B1, the 4km branch from Bologna to Conca D'Oro which opened in June.
Since CAF has supplied 53 trains to Rome Metro, which are used on lines A, B and Rome – Lido line.
The order is a confirmation of the CAF's determination to play a greater role in the Italian market. The company is currently delivering eight Civity regional emus to the region of Friuli Venezia Giulia, has a contract to deliver five tilting dmus to Sardinia, and signed a contract late last year for the supply of 250 bogies for the Milan Metro.
The Rome order also comes just days after the Executive Board of Helsinki City Transport approved the acquisition of 20 metro trains from CAF at a cost of €140.4m.
