The rolling stock uses standardized car bodies, articulated together. The number of cars varies across the different systems where they are used. The trains used on the Princess Nora bint Abdul Rahman University system are two car units. For the other systems, the units vary between three and six cars, making the trains from long. They are wide, except the Rome Metro units and the Honolulu Rail Transit units. The units vary from tall. Each car has two doors on each side, which are wide and tall. The vehicles are designed by Giugiaro Design. The three and four-car trains have six three-phaseasynchronousmotors per train, with each motor giving a power output of, giving each train a power output of. In each car, the two motors are fed by the car's own insulated-gate bipolar transistor. They transform the 750-volt direct current collected from the third rail shoe to the three-phase alternating current used in the motors. The trains' top speeds are, with an acceleration and deceleration capacity of 1.3 m/s2. Trains are fully compatible with platform screen doors, which are found at all stations in Brescia, Rome and Milan, Copenhagen, and Thessaloniki.
Automation
The systems are controlled by a fully automated computer system, located at the control and maintenance center. The automatic train control consists of three subsystems: automatic train protection, automatic train operation and automatic train supervision. The ATP is responsible for managing the trains' speed, ensuring that doors are closed before departure and that switches are correctly set. The system uses fixed block signaling, except around stations, where moving block signaling is used. The system has been designed and built by Union Switch & Signal. The ATO is the autopilot that drives the trains in line with a pre-defined schedule, ensures that the train stop at stations and operates the doors. The ATS monitors all components of the network, including the rails and all trains on the system, and displays a live schematic at the control center. The ATC is designed so that only the ATP is safety-critical, and will halt trains if the other systems have faults. Other aspects of the system, such a power supply, ventilation, security alarms, cameras and pumps, are controlled by a system called "control, regulating and surveillance". The most common repairs are the grinding of the wheels; more complicated repairs are made by replacing entire components that are sent to the manufacturer. By having components in reserve, trains can have shorter maintenance times. The center also has the system's work trains, including a diesel locomotive that can fetch broken trains. At any time, there are four people working at the control center. Two monitor the ATC system, one monitors passenger information, while the last is responsible for secondary systems, such as power supply. In case of technical problems, there is always a team of technicians who can be sent to perform repairs. Although the trains are not equipped with drivers, there are stewards that help passengers, perform ticket controls and assist in emergency situations.
Operators
Brescia
The Brescia Metro is a system which opened in March 2013 in Brescia, Italy. The system was built in three stages and has 17 stations. The system features a 90-second headway. ASM Brescia ordered 18 trains which are now being used on the Metro.
Copenhagen
The Copenhagen Metro, Denmark, consists of four lines, M1, M2, M3 and M4 that run serving 37 stations. The system opened between 2002 and 2019, and connects the city center to the areas of Frederiksberg and Amager, and Copenhagen Airport. The next extension, the City Circle Line opened on 29 September 2019. Metroselskabet took delivery of 34 three-car units between 2002 and 2007, and operates with a headway of between two and twenty minutes, including an all-night service. In April 2008, the Copenhagen Metro won the award at MetroRail 2008 for the world's best metro.
The Honolulu Rail Transit project will be a elevated rail route which will connect the city of Honolulu on the island of Oahu in Hawaii with outlying suburbs. The project is planned to open in phases starting in late 2020 with the entire 21 station route to be completed in late 2025. AnsaldoBreda Driverless Metro rolling stock will be used for the system. Honolulu politicians and construction crews broke ground on the project on February 22, 2011 in Kapolei, Hawaii. As of October 2012, construction of the columns and foundations have been completed for the first mile of the route. Future extensions to the route have been planned, which include spurs to the route and 15 additional stations. Construction of the project is currently on hold as litigation resulting from Kaleikini v. Yoshioka court case bars continuation of the project until the City and County submits a complete archeological survey to the State Historic Preservation Division for the entire line.
Lima
It is currently under construction in Lima the Line 2 of Lima Metro and a branch of Line 4, which will connect the city of east to west in the first case and the portion of line 4 linking the Jorge Chavez International Airport with the line 2. the line will be built in two phases, the first of which is scheduled to open in 2017 and the second in 2020. the total of the 2 lines will cost US $5,346,000
Milan
The Milan Metro's Line 5 first section between Bignami and the interconnection with M3 at Zara opened on 10 February 2013. The second stage opened on 1 March 2014, and runs from Zara to Porta Garibaldi station. The third and fourth sections are under construction and are both planned to open in 2015, and will run from Garibaldi to San Siro stadium and from Bignami to Monza. Further extensions are planned. The first stage of was estimated to cost €500 million.
's Line C is long, of which are underground. Metropolitana di Roma has ordered thirty six-car units, which are wider than the other systems' vehicles, and capable of carrying 1,200 passengers per train. Average speed on the system is, with the headway varying from three to twelve minutes.
Taipei
The Yellow Line or Circular Line of the Taipei Metro, Taiwan, will serve as a cross-link between existing lines. The system will feature 42 or 41 stations. The phase 1 have 14 stations and is completed in January 2020. The Taipei Rapid Transit Corporation purchased 17 trains for this phase.
Thessaloniki
Construction on Greece's second metro system began in 2006 and is scheduled to open in phases between 2020 and 2021, at a cost of €1.57 billion. The system will feature 18 stations in 2021. 33 driverless AnsaldoBreda units will be put to operation on the two lines. Those will be articulated in 4 sections with a capacity of 466 passengers.
