Testing started with commissioning systems such as brakes, passenger information displays, lighting and door operation and then moved on to track tests involving acceleration, braking and operation at different speeds.


Sydney Metro says train testing will progressively transfer to Cudgegong Road station and the 4km elevated section of the new 36km line before trains start running through the new 15km twin-bore tunnels between Bella Vista and Epping. Testing is being done in close consultation with the National Rail Safety Regulator.

The new line, comprising the Cudgegong Road - Epping section and incorporating the existing Epping - Chatswood commuter line, is expected to open in the first half of 2019.
