Program 4 will focus on accurate prediction and track performance under realistic dynamic loading and being able to estimate the lifespan of track elements and associated maintenance costs and imperative for sustainable railroad operations. Conventional vibrating wire instruments do not provide precise data when subjected to rapid and dynamic moving loads. Recent use of sensor technology using optical fibre (FBGs) enabled much improved accuracy in heavy haul tracks for the first time in Australia.
