This project, managed by tram operator Keolis Downer, has significantly reduced a severe wheel squeal noise problem on St. Kilda Road, Melbourne, Victoria. Given TOR friction modifier (FM) use for noise abatement was new to Yarra Trams, a comprehensive trial evaluating impacts to vehicle braking/traction and effectiveness as a noise solution was conducted with success, confirming the proposed embedded track wayside solution was safe and viable for ongoing Melbourne tram network use. Noise monitoring results have confirmed the applied TOR technology to be efficacious, with a significant reduction in wheel squeal events following installation of the wayside equipment, combined with mostly positive feedback from residents in the Domain precinct. Further work evaluating possible additional TOR friction control technology benefits mitigating rail wear and corrugation growth are planned for investigation. 1. INTRODUCTION implementation of an embedded track TOR system automatically dispensing the FM The Yarra Trams franchise is the world’s largest product during tram operation.
