Operation

The line is equipped with a third-rail power supply at a voltage of 750 V in

direct current Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or eve ...

. It is the first line in Milan with a fully automatic management and driving system, as well as the first to have platform screen doors. The entire line is controlled and managed by a single control centre, located at the depot at the Bignami terminus. The line is connected to the rest of the network by a track between Isola and Garibaldi FS stations, which allows trains to reach the M2 line and then the Precotto depot on the M1 line, the closest one that is able to carry out repairs. The platforms and trains are 50 meters long, compared to 110 of the other three lines of the Milan Metro. However, thanks to very high frequencies the passenger capacity is high at 24,000 passengers per hour. Although the complete automation allows a maximum frequency of one train every 90 seconds (75 in some cases), the current maximum frequency is 150 seconds due to the limited number of trains available.
