First driverless metro opens in Sydney

A self-driving metro pulls into Tallawong Station in Sydney, Australia on May 26, 2019. Running between Tallawong and Chatswood, the eight station, 36km line has taken eight years to build, but has come in more than $1 billion under budget. The driverless train service is the first of its kind in Australia. It can carry nearly 18,000 passengers per hour. [Photo: IC/Getty Images/Matt Blyth]
