List of automated urban metro subway systems

Grade of automation levels:
 * In a Grade of Automation 4 (GoA4) system like the Copenhagen Metro, trains are capable of operating automatically at all times, including door closing, obstacle detection and emergency situations. On-board staff may be provided for other purposes, e.g. customer service, but are not required for safe operation.
 * In a Grade of Automation 3 (GoA3) system like the Docklands Light Railway, trains run automatically from station to station but a staff member is always in the train, with responsibility for door closing and handling of emergency situations. In a GoA3 system, the train cannot operate safely without the staff member on board.
 * In a Grade of Automation 2 (GoA2) system with ATO like London Underground Victoria line, trains run automatically from station to station but a driver is in the cab, with responsibility for door closing, obstacle detection on the track in front of the train and handling of emergency situations.

Defunct systems

 * Berlin M-Bahn - This was a maglev train in West-Berlin in operation from 1989 to 1991. It closed when a metro line, on which the M-Bahn's route partly lay, was scheduled to reopen. The metro line was closed in 1961 when the Berlin Wall erected, because it crossed the border.
