Axlebox accelerometer (ABA) systems offer a means of measuring or monitoring the longitudinal profile of track at a relatively high speed over the wavelength range associated with corrugation: typically 10–1000 mm. There is little or no published data on the use of ABA systems for measuring longer wavelengths, in particular 1000–3000 mm. This paper provides data from one ABA system which was mounted in a road-rail vehicle that was used as a track recording car. Repeatability and accuracy are assessed in a similar and novel way that has not previously been presented in the literature. Both are shown to be quite acceptable throughout the wavelength range 10-3000 mm, with a correlation coefficient exceeding 0.9 for both repeatability and accuracy.
