Train testing starts in north west tunnels

The train testing took place in the first two kilometres of tunnels between the new Bella Vista and Norwest stations.

Onboard systems were tested as well as signalling, braking and acceleration at different speeds in the tunnel. Testing will progressively increase up to 100km/h.

Over the coming months it will be tested beyond Norwest through the full length of the new tunnels.

More than 10,000km of train testing has taken place so far on the Sydney Metro system, with 12 of the fleet of 22 trains delivered.
