Abstract
A method for the assessment of the quality of the railway track is presented, introducing speed as a stand-alone quality indicator. Speed is expressed by means of the maximum permissible track speed VTR, max, which is considered to depend upon the satisfaction of a predefined set of safety, comfort, and reliability criteria. Calculations are performed by means of analytical models. The method can be applied to any railway network, regardless of technical or operational characteristics; it can assist infrastructure managers in their track maintenance management decision-making process. Extensions of the proposed method are feasible in order to include additional speed-related performance criteria, e.g. noise and vibrations.
