For the first time, passengers have boarded Australia’s first turn-up-and-go train service, which is due to officially open in May more than $1 billion under budget.

Premier Gladys Berejiklian and Minister for Transport and Infrastructure Andrew Constance today experienced a test trip on the world-class driverless train which will run services every four minutes.

“It will be an historic day in Australia when the first full passenger service of the Sydney Metro departs from Tallawong station in Rouse Hill,” Ms Berejiklian said. “We are thrilled this $8.3 billion project will be finished on time and $1 billion dollars under budget.

“The Northwest Metro rail line shows that when the NSW Liberals & Nationals make a promise, we deliver on it.” Mr Constance said Sydney Metro’s launch will deliver a better experience for train customers.

“Customers between Rouse Hill and Chatswood will quickly fall in love with Sydney Metro and it is not hard to see why,” Mr Constance said.

“We delivered this service for the people of Sydney’s Northwest, but we are not done, with the Metro currently being extended from Chatswood, under the Harbour and onto Bankstown. “You can trust the NSW Liberals & Nationals to deliver for the people of NSW, but you can’t trust Labor.

“When they were last in office Labor promised 12 rail lines and didn’t deliver a single one and now they want to cancel the Sydenham to Bankstown Metro upgrade, depriving Sydney’s South West of world class Metro services.”

The entire 22 train fleet has been delivered and more than 35,000km of train testing has taken place on the Metro system through all 13 stations along the railway.

Stage 2 of Sydney Metro, the City and Southwest line from Chatswood to Bankstown, is on track to have services running in 2024.
