This paper is focused on a comparison between the axle-box and bogie mounted accelerometers for the track condition monitoring by in-service high-speed trains. A method based on Kalman, band-pass, compensation filters are introduced to estimate the lateral and vertical track irregularities from the corresponding axle-box or bogie accelerometers. Also, the rail vehicle dynamics software is used to analyse the estimated result and to verify the developed method. (6 pages)
