Vincent, N. (author), Bouvet, P. (author), Thompson, D.J. (author), Gautier, P.E. (author), Technisch Physische Dienst TNO - TH (author)The control of railway rolling noise requires a reduction in wheel and track noise emission. In this paper, a parametric study of the possible minimization of the track sound power is presented. In an initial global approach, a number of potential variations in track parameters are assessed in terms of their likely effect on rolling noise. From...article 1996

Janssens, M.H.A. (author), Thompson, D.J. (author), Technisch Physische Dienst TNO - TH (author)The sound level of a train crossing a steel railway bridge is usually about 10 dB higher than on plain track. In the Netherlands there are many such bridges which, for practical reasons, cannot be replaced by more intrinsically quiet concrete bridges. A computational model is described for the estimation of noise levels due to a train crossing a...article 1996
