Abstract
A survey of freight locomotive passby noise emissions has been undertaken across five locations on the RailCorp network, including identification of “subjective outlier” events. This paper describes the objectives of the survey, the measurement locations and methodology. Results are presented in the form of statistical parameters for each measurement location, as well as parameters categorised by operating condition (up steep grades, down steep grades and on straight and level track).
It can be seen that high LAmax passby levels do not correspond to events identified as subjective outlier passbys. The LCmax parameter was observed to correspond reasonably well with subjectively assessed outlier events, in both the uphill and downhill directions at all locations.
