What is the name of the fully driverless metro system serving Copenhagen, Denmark?

The fully driverless metro system serving Copenhagen, Denmark, is the Copenhagen Metro.

The system opened in October 2002 with the M1 and M2 lines, linking central Copenhagen with areas including Frederiksberg and the island of Amager. Its trains operate without drivers using automatic train protection, automatic train operation and automatic train supervision. Staff may still ride aboard trains to assist passengers, check tickets or respond to emergencies, but they do not drive the vehicles.

The Copenhagen Metro is integrated with Denmark’s wider public-transport network. Passengers can connect with DSB trains, the Copenhagen S-train network, regional Øresundståg services and Movia buses. Platform screen doors help separate passengers from the tracks, a feature especially useful on an automated railway.

The network later expanded with the City Circle Line, M3, opened in 2019, and the M4 line, which began service in 2020. A common mistake is choosing Copenhagen S-train: it is another important rail system in the city, but it is not the fully automated metro named in the question.
