Abstract

A methodology for a preliminary service dependability estimation of the new Italian high speed railway system is illustrated in the paper. The following subsystems have been analysed: high voltage transmission network; electric substations; overhead contact lines; signalling. The effects of the main event perturbing the railway service have been considered by simulating the different traffic management in degraded conditions. Simulation results, expressed in terms of train delay frequency distribution, are illustrated in the paper. 1 Introduction Of the various problems posed by the design of high-speed railway lines that of determining the reliability of the system as a whole is undoubtedly of r
