ABSTRACT
The article discusses investigation on the use of a multiplexed array of optic fibre strain sensors to monitor stresses in rail joints and other track components on England's Sheffield Supertram network. The probe is part of the Association of the European Rail Industry-led research into "Predictive Maintenance Employing Non-intrusive Inspection & Data Analysis." The potential role of innovative monitoring techniques in the continuing battle to maintain ever-busier railways is also noted.
