Train testing begins on metro line under Sydney Harbour
City & Southwest project’s 15.5km twin tunnels are the first to pass under the waterway.
HISTORY has been made in New South Wales as for the first time test trains are running deep below Sydney Harbour as the Sydney Metro City & Southwest project enters its latest stage.
As part of the testing and commissioning programme for the new trains, they are travelling at an initial 25km/h through the 15.5km-long twin tunnels which extend the Metro North West Line from Chatswood to Sydenham.
Train speeds will be gradually increased to a maximum of 110km/h and each train will also undergo acceleration, braking and systems checks on the newly-completed line to ensure reliable operation under normal service conditions.
