dc.description.abstract In the recently published paper by Real et al. entitled ¿Determination of Rail Vertical Profile through Inertial Methods¿ the authors used a particular method to establish the correspondence between the vertical accelerations registered in the axlebox of a wheel and the rail vertical profile which caused them as a way of monitoring the track conditions. This work does not consider the filtering effects due to the asymmetric chord that introduces the Infrastructure Monitoring Vehicle VAI used in the tests. As a result of this, it is suggested that such method may produce some errors in the measurements at certain frequencies. The present work shows how the technique can be amended in order to maintain its quality. es_ES
