In 2001 CAF signed a framework agreement with Comune di Roma for the supply of 45 Units. These units consist of 6 cars with an unobstructed corridor that enables passenger traffic along the whole train. The train integrates two independent traction units within a single control system.
Regarding acoustic and visual passenger information systems, these trains are fitted with the Passenger Address System, exterior line signs, interior signs and information video screens, among others.
These units have been delivered under several orders raised by the Customer. The trains operate on Lines A and B of the Italian capital metro network.
