This is a list of driverless train systems, which are capable of GoA3 and GoA4 (GoA3+) according to the Grade of Automation classifications specified by the standard IEC 62290âÂÂ1. These are explained diagrammatically by the UITP. This list focuses heavily on trains in the classical sense used for large-scale railways for passengers and freight but does include a few people mover systems. For a similar list for GoA2, see list of semi-automatic train systems.
These systems are capable of driverless train operation (DTO), but a train attendant operates the doors and drives the train in case of emergencies.
These systems are capable of unattended train operation (UTO), although some operators may choose to staff trains anyway.
