This study was carried out to determine the reliability of the methods of transmission of information about the location of a train to the train control center using a digital radio channel and a method based on Distributed Acoustic Sensing (DAS) technology. The study results were obtained based on the MATLAB R2024b model and showed resistance to external noise in fiber-optic communication with DAS technology. The proposed information transmission method allows the joint use of fixed- and moving-block section concepts in train traffic control systems. The effectiveness of the joint application of the concept of fixed and moving-block sections was analyzed using OpenTrack V1.10 microscopic simulation using the parameters of the operating railway section Kurozek-Ekpindi-Jarsu, locomotive TE33A series, trains No. 3002 and No. 3004, and the interval control system. The obtained research results in the form of a diagram showed the effectiveness of the proposed method of duplicating the concept of moving- and fixed-block sections. The reduction in inter-train intervals contributes to increasing the capacity of the railway line and is the key to the economic efficiency of railway transport.
