With the need that railroads and transits have for sustainable service delivery, there is an ever-increasing demand to improve transportation efficiency, the challenge being to determine and understand the 'state of good repair' of a rail or transit system in real-time or near real-time. Prioritising track maintenance before conditions cause vehicle damage or derailments, and balancing the risk between operations, safety and maintenance cost, are fundamental to delivering a world-class transportation service. Railroads throughout the world are turning to new technologies to optimise track maintenance planning. This includes the use of revenue service vehicles equipped with sensors that quantify conditions and automatically report the location and severity of potential and functional failures to maintenance managers and engineers. This article gives a broad overview of how railroads and transits in the USA, Canada, Mexico and Australia utilise vehicle/track interaction diagnostic equipment to determine the 'state of good repair'.
