Empirical and semi-empirical (hybrid) models are commonly used in the prediction of vibratory impact of future railway lines. This paper focuses on the potential impact that a number of details can have on the accuracy of this type of vibration predictions, particularly when experimental assessment of vibration transmission characteristics is carried out. These aspects include different alternatives for installation of vibration transducers, use of different artificial vibration sources, ground borne noise estimation from vibration levels and also the role of some particular surface characteristics in the test site. A number of good practices concerning these aspects are summed up and suggested as a conclusion to help in improving the quality of future vibration predictions based on this sort of models.
