Yes, the Vancouver SkyTrain is one of the longest and oldest fully automated (driverless) rapid transit systems in the world. Since it opened in 1986, the system has used an advanced automated control system that allows trains to operate without any staff on board. The Expo and Millennium lines use Linear Induction Motor (LIM) technology, where the train "pulls" itself along a flat metal rail on the track using electromagnetic force. The Canada Line, while using more conventional electric motors, is also completely automated. This automation allows the SkyTrain to maintain incredibly high frequency—often with trains arriving every 2 to 6 minutes—and a high degree of on-time reliability. Because there are no drivers, the system can quickly scale capacity during special events or peak hours. While "SkyTrain Attendants" roam the system for safety and fare checks, the actual navigation, braking, and station stops are handled entirely by a centralized computer system.
