Testing and commissioning will start from October 2017, initially around Moore Park and Randwick with overhead wiring being erected in the precinct.
The testing and commissioning process takes place in three stages:
Installation of overhead wires
Once poles are installed, a specialised crew will begin installing cantilevers, cross spans and supports to each pole that will support the overhead wires (also known as catenary) along the alignment. The crew will then pull lengths of the overhead wire and attach from pole to pole before performing final adjustments and testing.
Energisation of overhead wires
When the overhead wires are in place and testing is complete, they will be energised. New signs will be installed along live sections, warning that the area is now energised. Contact with wires must be avoided at all times.
Light rail vehicle testing
When final safety checks are complete on the light rail systems, vehicle testing will begin. The first movements will be within the Randwick Stabling Yard, and along Alison Road and Anzac Parade. Vehicle testing will initially be carried out at low speed, gradually increasing as tests are verified. New signage and traffic signals will be in place and we’ll be providing more information to the community about safety around the new light rail vehicles when testing begins.
