Hitachi Rail Italy Driverless Metro
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 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.
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 2-car units. For the other systems, the units vary between three and six cars, making the trains from 39 to 109 m (127 ft 11+3⁄8 in to 357 ft 7+3⁄8 in) long. They are 2.65 m (8 ft 8+3⁄8 in) wide, except the Rome Metro units which are 2.85 meters (9 ft 4+1⁄4 in) wide, and the Honolulu Skyline units which are 10 ft (3,048 mm) wide to comply with Federal Railroad Administration regulations. [citation needed] The units vary from 3.4 to 3.85 m (11 ft 1+7⁄8 in to 12 ft 7+5⁄8 in) tall. Each car has two doors on each side, which are 1.3 m (4 ft 3+1⁄8 in) wide and 1.945 m (6 ft 4+5⁄8 in) tall. The vehicles are designed by Giugiaro Design.
The three and four-car trains have six three-phase asynchronous motors per train, with each motor giving a power output of 105 and 128 kW (141 and 172 hp), giving each train a power output of 630 or 764 kW (845 or 1,025 hp). In each car, the two motors are fed by the car's own insulated-gate bipolar transistor. The trains are powered by 750 V bottom contact third rail in most applications, although in Honolulu the same voltage is used but the third rail instead top contact, while Rome uses 1500 V overhead wires. The trains' top speeds are 80 to 105 km/h (50 to 65 mph), with an acceleration and deceleration capacity of 1.3 m/s/s (2.9 mph/s). Trains are fully compatible with platform screen doors, which are found at all stations in Brescia, Rome and Milan, Copenhagen, Honolulu, and Thessaloniki.
The systems are controlled by a fully automated computer system, located at the control and maintenance center. The automatic train control (ATC) consists of three subsystems: automatic train protection (ATP), automatic train operation (ATO) and automatic train supervision (ATS). 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 can be stewards that help passengers, perform ticket controls and assist in emergency situations.
The Brescia Metro is a system which opened in March 2013 in Brescia, Italy. The 18 km (11.2 mi) 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.
