A specific approach to the electronic systems of the responsible technological process control specially in railways has been applied for many years and it has been well acknowledged. This approach is based on system fail-safe behavior. Attempts of railway automation and telemechanics construction based on special non-contact elements were based on specialized failsafe elements. It was considered that the proved conventional approach could solve as well the safety problem of appearing new generation system. Besides the achievements on this field no elaboration has obtained industrial and operational significance. The purpose of this paper is to construct and research electronic track receiver for safety-related processes information transfer. Electronic scheme is proposed for heterodyne element that works in low-frequency range. The computer model is developed for different circuits electronic components- frequency transducer, resonance amplifier, selective finite element and passive elements.
