Testing and commissioning of the CBD and South East Light Rail is now underway with the installation of overhead wires and testing and commissioning of electrical systems and vehicles.

Before we can operate the new light rail system with passengers on board, we need to ensure that the system is fully functional and safe for public use. This takes several months of comprehensive testing prior to the operation of the first light rail service.

Testing and commissioning will be carried out in sections across the alignment, after which our drivers undertake training before the full line is tested prior to operation.

  • Road conditions may have changed
  • Trams cannot stop easily or quickly
  • Trams are quiet, pedestrians should look out before they step out
  • Cyclists should cross tracks on an angle



Tram testing

Night time tram testing has been underway in Randwick since February 2018. As new areas are energised, tram testing will continue to expand in Surry Hills, the CBD, and Kensington and Kingsford.

Vehicle testing will initially be carried out at low speeds and at night, gradually increasing speeds as the vehicles are tested under a number of conditions, including load testing. Testing will then progress to day time testing before driver training and the full-line is tested prior to operations.

Testing and commissioning

The testing and commissioning process takes place in three stages.

Stage 1: Installation of overhead wires

Stage 2: Energisation of overhead wires

Stage 3: Light rail vehicle testing

Hazard Zones and Permit to Work

During testing and commissioning of the light rail, hazard zones are established to help identify areas of increased risk including electrical hazards and tram movements. All works in a hazard zone require an approved Permit to Work before proceeding. The following are examples of the types of activities that may require a permit when working in or near a hazard zone:

  • Erecting ladders or scaffolding
  • Establishing work stations
  • Tree pruning
  • Operating excavators, cranes or any other plant equipment
  • Operating forklifts or any other heavy machinery
  • Delivering equipment/goods from large or oversize vehicles

Any other work activity that has the potential to take place within the hazard zone or come within 3 metres of poles and wires will require a Permit to Work and have a Person in Charge (PIC) assigned to them. Please contact the project team and they will assess the works to determine whether a Permit to Work is required.
