The SkyTrain is the rapid transit rail system serving Metro Vancouver, British Columbia. It uses mostly Advanced Light Rapid Transit (ALRT) technology, an automated rail system that operates mainly on a raised guideway, although some sections run underground or at street level. Regular service began 3 January 1986. The SkyTrain’s opening coincided with Expo 86, the world’s fair hosted by Vancouver as part of its 100th anniversary celebrations. The system is run by TransLink, the provincial transit agency for the South Coast of British Columbia. It was the world’s first driverless urban rail system. Now, it is one of the longest fully automated rapid transit systems in the world. The SkyTrain has three lines connecting 53 stations in seven municipalities. In 2018, it had more than 495,000 boardings per weekday, on average.
