Sydney (approx. 5.3 million inhabitants), capital of the state of New South Wales and largest city in Australia.
In 2019, Sydney added its first metro line to its extensive suburban railway. It is also expanding its light rail network with urban tram lines after having closed its large street tramway network, one of the longest in the world at the time, in 1961.
Sydney Metro opened its first 36 km section in May 2019 to serve the outer north-western suburbs. The fully automated line runs from Chatswood to Tallawong with 13 stations using platform screen doors throughout. It is known as metro north-west, rather than by a line letter and number like the rest of Sydney’s transit system. It includes 28 km of tunnels, 15.5 km of which were new, as well as 12.5 km of existing tunnel which it took over from Sydney Train’s T1 commuter railway between Chatswood and Epping.
