methods of mathematical statistics. Results: characteristic dependencies of the effective EMF value induced in the receiving coils of onboard safety equipment by the external electromagnetic field were constructed with changes in suspension height relative to the running rail head level, lateral displacements relative to the vertical axis of the running rail, and distance from the motor rotation axis. The spectral composition of the interference was determined. Practical importance: the obtained results refine the nature of the electromagnetic environment under operating conditions of automatic cab signaling with automatic speed regulation on subways, verify previously obtained results of computer modeling and developed mathematical models, and will be used in the future to improve service support for onboard equipment.
