The article discusses the problems of existing methods of receiving automatic cab signalling on
railway transport, an original method of receiving and processing data is proposed.
The need to solve the problems is due to the requirement of a qualitative improvement in the
reliability of receiving codes, and as a consequence, the capacity of existing lines. First of all, this
refers to a signifi cant increase in the quality of reception and processing of information fl ows from
rail lines. Today it is diffi cult to imagine the organization of the movement of rolling stock without
relying on automatic block systems with secondary sealing of tonal track circuits by frequency modulation signals or automatic cab signaling without the use of multivalued automatic cab signaling
with phase-diff erence modulation. Taking into account the objective fact of noise emission from the
operation of energy-intensive railway equipment and modern locomotives, the issues of reliability
and noise immunity of receiving discrete information (including signals of traditional automatic
cab signaling) are becoming more and more urgent. Analysis of the reasons for the decrease in the
reliability and noise immunity of railway automation and telemechanics systems, and, consequently,
traffi c safety also comes to the fore.
