The article discusses one of the sensors that is widely used to determine the location of a train with an axle counting system, namely the axle counter, since various types of sensors, such as track circuits, eurobalises, etc., are widely used in railway automation at stages and stations. The study consists in identifying the failure of the railway car counting axle under the influence of disturbing factors, namely the influence of weather conditions, terrain, the influence of rail magnetization, which leads to a malfunction of the axle counting system. The research method was to determine the failure in the calculation of the axles of the train, when, for unknown reasons, false information was shown, it turned out that when switching from diesel traction to electric rail, it is a grounding circuit, and the electrochemical effect also manifests itself, which leads to the accumulation of electrical energy. The research method consists in determining these factors; for this, algorithmic expressions were developed and the principle of operation of the axle counter was investigated. As a result, it was found that with electric traction, rail magnetization and magnetization between rail tracks, an accumulator effect, occur. The influence of the disturbing factor is calculated and shown by the distance to the sensitive element of the control sensor, the magnitude of the electromagnetic field intensity modulus, which affects the operation of the axle count sensor. In conclusion, protection methods based on adaptive protection methods are proposed.

“…As the study shows, in the majority of rail transportation, more and more often, both on hauls and at stations, traffic goes along mixed lines [1], high-speed lines are linked with the autoblocking system [2], therefore, when preparing routes, all restrictions on route preparation should be removed [3]. Hence, the station systems are interconnected with the haul systems, but if the haul is equipped with a semi-automatic blocking system [4], and here profile and distance of track bed do not have a clear distribution between stations, respectively, taking into account the regulations for receiving a train at a station, it increases several times [5][6][7][8][9][10][11][12].…”

On railways of the Republic of Uzbekistan, on hauls "Dashtabad - Zarbdar" and "Dashtabad - Bayaut" on section Tashkent - Samarkand and Navoi - Bukhara - 1, on section Samarkand – Bukhara organized high-speed train traffic, where hauls with a SAB microprocessor system were modernized on basis of axle counting system, produced by "Promelectronica". For the preparation of routes when departing or receiving at station, especially on high-speed sections, preparation is carried out with a large investment of time, which, in turn, interrupts the technological work carried out at the station. Offered with microprocessor semi-automatic lock on the axle counts, apply for establish routes RFID points, because maintenance and economic component are minimal. Accordingly, after examining the points and deriving analytical equations, algorithms and software tools were proposed. Key words: high-speed line, high-speed traffic, train, station, stage, mixed traffic, microprocessor-based semi-automatic blocking.

“…But there are practically no studies and publications on the adaptation of the solution of problems of analysis and optimization of the parameters of continuous welded rail circuits with an adaptive receiver in various working regimes [4]. In this regard, the development of a combined system for synthesizing and analyzing operation of a continuous tonal track circuit, taking into account the operation of a locomotive receiver, seems relevant [5].…”

In article discusses models of unlimited track circuits with a receiver, adapting to different working conditions, applied double receiver with one power supply in the middle, which allows you to extend the length of the continuous rail circuit. For this, a goal is set, in which is the development of models of jointless track circuits with an adaptive receiver, in which the rail line must take into account the total stress distribution along the rail line and disturbing factors. The article presents the equivalent circuits of continuous welded rail circuits with an adaptive receiver, algorithmic expressions for determining currents and voltages at the ends of the rail circuit, the coefficients of rail lines with an adaptive receiver are developed, calculation algorithms are presented. In conclusion, a graph is given, according to which it is shown that a continuous rail circuit with an adaptive receiver can operate with an insulation resistance three times lower than the threshold value in any modes of the rail circuit, taking into account the fact that, minimum allowable insulation resistance for tone-on-tone continuous rail circuits is taken as Ri=0,7ohm*km. Derived for the theory and synthesis of solutions, and also proposed new approaches to ensure the operating modes of the rail circuit, taking into account the real and weather conditions of operation.
