Railway track will settle due to the permanent deformation in the ballast and underlying soil.
A new track is straight and well levelled. After having been used some time, the track loses its perfect track geometry due to the train traffic. The severity of the settlement depends mainly on the quality and the behaviour of the ballast, the sub-ballast, and the subgrade.
