Computational analysis of electromagnetic field exposure in passengers near high- current contact wire environments.

The article focuses on analyzing the distribution of electric fields and magnetic flux density in human tissues of passengers waiting on platforms at multi-track high-speed railway stations, generated by high currents in contact wires. Using electromagnetic simulation software, a model with six contact wires and four passengers was developed to assess exposure under various loading conditions, including when tracks are occupied or unoccupied. Results show that even under maximum current loads, the electric field and magnetic flux density values in passengers’ tissues remain below the public exposure limits set by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines. These findings suggest that the electromagnetic environment in such railway stations does not pose a health risk to waiting passengers and provide data useful for designing electrified rail transit systems and establishing related safety standards.
