First look inside skytrain

The the first look inside Sydney Metro Northwest’s skytrain.

Some of the 1400km of steel cables which help hold the Sydney Metro Northwest skytrain together.

This is the first look inside Sydney Metro Northwest’s skytrain, held together by more than 1400km of steel cables.

“The 4km skytrain from Bella Vista to Rouse Hill is taking shape before our eyes,” Minister for Transport Andrew Constance said.

“This is the first chance we’ve had to take a rare look inside this giant structure, an engineering marvel which will change the way of life for the north west.”

Inside the skytrain, black pipes run the length of the structure carrying about 37,000 high tension steel cables.

These cables pull together and secure the 1200 concrete segments which make up the 4km elevated structure.

Construction continues on the 4km Sydney Metro Northwest skytrain.

If the steel cables were laid end to end they would stretch more than 1400km, a distance equivalent to Sydney to Rockhampton, Queensland.

Large cranes lift the concrete segments into place and the segments are then glued together before each span is tensioned using the steel cables.

The latest update on the skytrain follows the completion of the skytrain section over Memorial Avenue, Kellyville, last month.

Once the skytrain is built work will start on the elevated railway stations at Kellyville and Rouse Hill, which will be two of eight new metro stations.

Sydney Metro Northwest will be the first fully-automated metro rail system in Australia and is on track to open to customers in the first half of 2019.
