Summary A series of tests have been undertaken on the French railway system to examine whether a commercially available system based on axlebox accelerometers offers a viable method of measuring amplitudes of railhead roughness that are significant for wheel/rail rolling noise. The HSRCA system that was tested gives repeatable measurements and a good estimate of acoustic roughness provided the measuring speed is similar to that at which the system is calibrated and the dynamic behaviour of the trackform is similar to that on which the system is calibrated. The tests described below will demonstrate tentatively that the HSRCA offers a promising means of undertaking noise monitoring of a railway network.
