The Preliminary Noise Report for the Caulfield to Dandenong project, prepared by noise and vibration experts WSP | Parsons Brinckerhoff, was released today.
The report confirms the proposed design meets established noise criteria for both airborne noise emissions from rail movements, as well as ground borne noise caused by vibration of the elevated structures. The majority of houses and businesses near the project corridor will experience an overall reduction in noise as a result of the plan to elevate sections of the rail line.
Noise and vibration impacts will be reduced compared to existing conditions through the use of specific measures such as:
- noise walls and privacy screens to mitigate noise transfer
- new high-quality, continuous smooth tracks
- purpose-built resilient fastenings to attach the new tracks directly to the structure
- rubber insulators under the track to dampen vibrations
- design of train stations to reduce noise spill.
The project plans to undertake further modelling to ensure the final design continues to comply with all relevant noise criteria and project requirements.
