Abstract
In this paper, localised vertical geometrical faults at rail welds are considered. The aim is
to predict maximum permissible irregularity sizes at such faults, assuming continuously
welded track. To achieve this, the criteria of maximum accelerations and dynamic peak-
wheel-rail forces between welds can be used. Theoretical results were partly controlled by
experiments and discussed in relation to other studies
