Milan Metro 4400 series

The Milan Metro 4400 series is a rapid transit electric multiple unit operated by Azienda Trasporti Milanesi (ATM) on the Milan Metro since November 2022.
==History==
The 4400 series is the first generation of rolling stock to operate on Milan Metro's Line M4. It is the second type of light rolling stock introduced onto the Milan Metro network. The first set, 4401, was completed in 2019 and lifted into the premises for testing. The sets entered service in November 2022 with the opening of Line M4.
==Design==
The 4400 series is a member of the Hitachi Rail Italy Driverless Metro family, originally built by Hitachi Rail Italy's predecessor company AnsaldoBreda. The locomotive's exterior design was done by noted automotive and industrial designer Giorgetto Giugiaro and uses the basic design of the metro shared by a number of other similar systems using the Driverless Metro.
==Specifications==
The 4400 series uses a Hitachi IGBT variable frequency drive system.
As with all Driverless Metro sets, it features Automatic Train Protection (ATP), Automatic Train Operation (ATO) and Automatic Train Supervisory (ATS) systems. Trains are controlled by a central control center and can be driven manually from the center in the event of an emergency; the computer-controlled system is said to eliminate human errors and offer a high amount of precision in the trains's operation.
