Issues of standardizing requirements for resistance and strength of railroad automation and signaling systems used in high-speed railways versus external mechanical impact

Abstract

We discuss the problems of adaptation of requirements for resistance and strength versus external mechanical impact for railroad automation and signaling systems used for Russian high-speed railways. We present an analysis of the requirements and test methods for resistance and strength versus external mechanical impact for railway railroad automation and signaling systems in the current Russian standards. Based on the classification of automation and signaling equipment, the requirements and tests are compared to the similar ones of the European standards used for the design of high-speed railway railroad automation and signaling systems. It is proven necessary to change the mechanical strength requirements imposed by Russian standards in the design of railway railroad automation and signaling systems. We considered the possibility of adaptation of requirements and test methods for railroad automation and signaling systems in the present Russian standards to the problems of design of high-speed railway equipment. In this paper, we provide recommendations for designers on how to select the requirements for resistance and strength versus external mechanical impact and test methods for railroad automation and signaling systems used in high-speed railways.
