The Hitachi Rail Italy Driverless Metro is a class of driverless electric multiple units and corresponding signaling system. Manufactured by Hitachi Rail Italy (formerly AnsaldoBreda) and Hitachi Rail STS (former name Ansaldo STS) in Italy, it is or will be used on the Copenhagen Metro, a people mover at Princess Nourah Bint Abdul Rahman University, the Brescia Metro, the Thessaloniki Metro, lines 4 and 5 of the Milan Metro, Line C of the Rome Metro, Skyline in Honolulu, and the Circular line of the New Taipei Metro. The first system to use this class of driverless electric multiple units was the Copenhagen Metro which was opened in 2002.
The rolling stock consists of two[1] to six articulated cars which operate on standard gauge. Each car has a power output of 210 or 256 kilowatts (282 or 343 hp), fed from a 750 V DC third rail (except in Rome where it is 1,500 V DC overhead line). The systems are fully automated, consisting of automatic train protection (ATP), automatic train operation (ATO) and automatic train supervision.
