Investigation into the critical speed of ballastless track [PDF]

open access: yesTransportation Geotechnics, 2019
Abstract As train speeds are increased, the issue of the critical speed must be faced, especially when tracks run across soft ground. This is the phenomenon describes the amplification of the track deflections due to coincidence of the train speed with the wavespeeds of the underlying ground.
