A prototype for a kilometre-long "green track" has been laid as part of the US$1.7bn Parramatta Light Rail line that will link the western and northern suburbs of the city via its central business district.
The green track includes planting grass or low plants between and beside the rail tracks.
The year-long process includes testing two types of grass to gauge their growth rate and durability, as well as experimenting with soil layers and depths. Some 3,500 trees will also be planted to create shade along the route.
Andrew Constance, New South Wales’ minister for transport, said: "We’re employing the latest research and technology to embrace grass track as an aesthetic and sustainable urban design solution. Green track contributes to increased biodiversity, noise reduction and urban cooling which are great outcomes for the people who live and work in the local area.
"This trial will enable us to see which grass type and irrigation system will be most suitable for our existing local landscapes, parks and streets."
The Parramatta Light Rail development is due to be completed in 2023.
