The purpose of a cab-signaling system, as well as basic functions, systems’ structure and modifications were described in the study. The comparative analysis of advantages and disadvantages of the existing systems was given. The system of multivalued cab-signaling of integrated continuous automatic cab-signaling (ICACS) common range was examined in greater detail. The method of coding algorithm modification of a railway line transmitted signal in the system of ICACS was introduced in the given study, as well as the analysis of jam proof properties of a system was carried out, in the process of replacing a modified Bauer code with a modular weighted summation code. An in-depth analysis of all possible false transitions of signal code combinations in a data transfer circuit was performed. The results of comparing detection capacity of the examined codes in a circuit were presented, as well as the main reasons of modern cab signaling systems failure The obtained methods of modification of data codification and code deciphering software modules made it possible to broaden the system’s valence by four times from 256 to 1024 program orders, satisfying safety requirements in the process of data transfer.
