Commuters brace for transport delays as Sydney T3 train line closes for year-long upgrades

Travel authorities are warning the closure of T3 train line from Bankstown to Sydenham could double the travel for some commuters during peak hour. It's part of a year-long process that will see the 130-year-old train line converted into a metro service. Bus services are being used to replace trains across Sydney's south-west and inner west.
