| dc.description.abstract | This paper presents an investigation of rolling noise emissions from trains operating on the Perth electrified passenger network, as an outcome of the Public Transport Authority's strategic initiatives in noise management. The study compared STARDAMP model results with field measurements for both ballasted and slab track, ex-amining scenarios with and without rail dampers, and identified the contribution of track and rolling stock to overall rolling noise emissions. The work demonstrates that noise from the Perth metropolitan passenger train network can be effectively attenuated using rail dampers. A rolling noise reduction of up to 5 dB was predicted and measured for passenger trains on ballasted track. In a tunnel situation with Pandrol Vanguard slab track a reduction of up to 8 dB was achieved. The efficacy of rail dampers as a noise control measure in Perth is at-tributed to the Perth rolling stock wheel design and track support dynamic stiffness. | en_US |
