Parramatta rail link: the approach to controlling train regenerated noise and vibration

There is an increasing awareness of the environmental effects of noise and vibration and a commensurate demand that sources should be controlled to levels that make life tolerable. Railways can be a significant source of noise and vibration, and so new rail projects are under increasing pressure to provide suitable means of reducing the nuisance of noise etc. This is even more critical in new underground railways, where it is difficult to avoid bringing the railway into close proximity with residential, or sensitive, properties. As a result the railway engineer has to consider how the rail infrastructure can be designed to deliver the required environmental outcomes. This paper discusses the statutory requirements limiting the allowable levels of ground borne vibration and regenerated noise for the Parramatta Rail Link, and how these have been addressed in the project design. It outlines the process of acoustic modelling to predict actual noise levels expected at surface receptors under normal train operation. It then compares the predicted noise levels with the required limits to give an indication of the degree of attenuation to be provided by the track structure. The paper then discusses the typical track construction/treatment options that are available, and concludes with discussion on the trackforms finally selected for the project.
