Sydney Metro says the train will be prepared for tests over the next few months, and the first trains will begin operating on the new line in the next two years.
The new trains feature three sets of double-doors per car for improved passenger access and flows, CCTV, emergency intercoms, the latest passenger way finding aids for customer information, and real-time travel information.
Alstom is also supplying the CBTC system for the new line which will enable trains to operate fully automatically at four-minute headways.
The new line is due to open in the first half of 2019 and includes 15km of tunnels and 4km of elevated railway linking Epping with Cudgegong Road with eight new stations. It will also incorporate the existing commuter line and its five stations between Epping and Chatswood which will be upgraded to automatic metro operation to create a 36km metro corridor.
The Northwest Rapid Transit consortium, consisting of MTR Corporation Australia, John Holland, Leighton Contractors, UGL Rail Services and Plenary Group, secured a $A 3.7bn operations, trains, and systems contract for the $A 8.4bn project in 2014.
