Sound Solution Works in Australia

Australian train operators are using the Rail Squeal Acoustic Detection system (RailSQAD), a new acoustic system that identifies noisy wheelsets in a highly-populated residential Adelaide Hills region. RailSQAD was developed for the Australian Rail Track Corporation (ARTC) by the Adelaide-based specialist acoustic engineers Vipac Engineers and Scientists and is a joint initiative of ARTC, the Environmental Protection Authority, and train operators. The primary objective of RailSQAD is to reduce wheel squeal noise emissions throughout this region. RailSQAD is an advanced acoustic array system which can detect, record, and trend a range of train wheel/rail noise sources from both freight and passenger trains and then identify the noisy ones for removal and repair. One benefit of using RailSQAD is that it allows operators to use it as a preventive maintenance tool to achieve 25% reduction in wheel wear and 3% improvement in fuel economy. Another benefit is the removal of nearly 90% of rogue bogies from the Adelaide-Melbourne sector, which decreases maintenance and rail grinding costs. A third benefit lies in the reduced risk of derailment from rogue bogies.
