The Effect of Overhead Line and Pantograph Failure for Railway Operations

Abstract

Rail transport is of strategic importance for acountry. In some circumstances, it is the fastest and safest transport option. However, this form of transportation also involves risks that need to be explored and handled appropriately. Such a risk factor is the failure of the superstructure, which can paralyse a longer or shorter section of a railway line. This includes overhead line breakdowns, the causes of which are revealed by dynamic simulation, while the resulting risks are examined by the methods of risk analysis. My goal is to design a system of protection using the methods of dynamics and risk analysis that can help reduce the occurrence of line breakage. Nowadays, the volume of rail transport  is increasing, the share of electric traction is on the rise in Europe, so it is of utmost importance to ensure that traffic is accessible.
