The article is devoted to the problem of determining the electromagnetic influence degree of electrified AC railways traction networks. The potential, induced by the field, can create a threat to life and health, create conditions for failure of low-voltage equipment, appear as a source of interference. This article considers some approaches to the calculation of electromagnetic field characteristics and gives a critical analysis of the methods used.

Fiber-optic data transmission lines (FOCL) are one of the main parts of automated data transmission control system, which controls technological processes of railway transportation. The lines are subject to powerful electromagnetic effects from traction power supply system. Improving the reliability of the entire system by reducing the electromagnetic influence and the optimal choice of the VOC location is a complex and urgent task, the solution of which will significantly improve the reliability and efficiency of the entire automated complex.
