The METRONET Byford Rail Extension project is more than just a new rail line and stations, it’s about protecting our environment, celebrating local biodiversity, and building a more sustainable future for the community.

Thanks to thoughtful design and smart planning, the project has set new benchmarks for sustainable infrastructure in WA. One of the biggest achievements has been saving more than 38 hectares of native vegetation, including one of the state’s last remaining Corymbia calophylla, Kingia australis woodlands.

Here’s how we created greener, cooler and more resilient station precincts:
•    88% of landscaping plants are local, drought-tolerant species.
•    Tree canopy cover will exceed 30 percent at Armadale and Byford stations, reducing urban heat and providing shady green spaces.
•    Salvaged grass trees have been carefully cared for and replanted across the station precincts.

Sustainability has been built into every step of the project. By using water-wise landscaping and innovative drainage systems, we cut lifetime water use by 38% and reduced permanent irrigation needs by 77%.

The project also leads the way in smarter use of materials:
•    We reused 9,700 concrete sleepers and 17,600 tonnes of ballast.
•    98% of construction waste and 100% of clean fill were recycled.
•    High recycled-content steel and low-carbon concrete were used across the project.
•    11 kms of recycled plastic noise walls were installed.
•    Solar panels are installed at both stations.
•    1530 tonnes of FOGO soil was used.

Both stations received a 6 Green Star Design Rating – the highest level of sustainability recognition. The METRONET Byford Rail Extension project has created a long-lasting legacy of environmental protection, sustainable innovation and a greener future for generations to come.
