“…2, a -For high-speed trains, the following expressions (4), ( 5), (6), and ( 7) are used to calculate the distance between the first and second control points in the figure as well as the rolling stock's time of movement. High-speed train braking times are expressed as follows: (4) for high-speed train braking times between 0 and 108 km/h, (5) for high-speed train braking times between 108 and 350 km/h, and ( 6) and ( 7) when braking is an expression of the path [15][16][17][18][19][20][21][22][23][24].…”

These days, automated rail traffic control systems help to lessen the need for human intervention in train traffic management. On the other hand, the various algorithms used by interlocking systems to coordinate the movement of trains belonging to distinct categories result in longer wait times for technological procedures at the station. The possibility of timely routes for trains of multiple categories occurs by employing the method of automatic route preparation by interlocking systems in the organization of the movement of trains of different categories. In interlocking systems, automatic route preparation can be achieved by continuously monitoring train characteristics, train traffic graphs of various train classes, and the condition of equipment involved in the function’s development. Nonetheless, it is predicated on the creation of many models to arrange the specifications of various train classes and train movements inside a single schedule type. In order to prepare the routes ahead of time for the station tracks based on the algorithms for the operation of interlocking systems for various kinds of trains, the paper analyzes the reliance of the traffic composition characteristics.

“…Currently, the automatic locomotive signaling system is one of the most important systems for ensuring the safety of railway transport when trains are moving [1][2][3]. It is impossible to ensure traffic safety without equipping railways with modern and reliable technical means [3][4][5][6][7][8][9][10]. tatochka83@list.ru; phone +99 890 966 91 89…”

“…The driver of a moving locomotive learns about the freedom or occupancy of the tracks of the next block section of the road with auto-locking, using an automatic locomotive signaling device (ALS) located in his cabin, but moves along the stretches and stations, obeying the indicators of the repeater traffic light [1,2,5]. Figure 1 shows a graph of the number of errors that occurred between the indicators of the repeater traffic light and the locomotive by rail chains in 2021.…”

“…In the event of a sudden appearance of a white signal at a locomotive traffic light, on stage and station tracks equipped with ALS devices, the driver, obeying the traffic light signals, must ensure traffic safety and stop the train in front of a forbidding traffic light. At the same time, together with the above actions, the driver must press the warning lever several times (at least 3) for 5-7 seconds and start hitchhiking (at least 3 seconds) using the EPV (electropneumatic valve) [3,5].…”

In the field of automation and telemechanics, the main task is to improve the automatic locomotive signaling system (ALS), including the creation of a complex of remote measuring devices using wireless, microprocessor and digital technologies to eliminate malfunctions on railway sections of automatic and semi-automatic locking. This article presents an analysis of errors in traffic light indicators and the automatic locomotive signaling system by month from the time of the year, which affect the speed of trains, namely, due to a false indicator, the speed decreases, this leads to lagging behind schedule, thereby due to the lack of timely arrival of trains, the company incurs financial losses. All malfunctions arising from a system failure are represented by mathematical expressions, on the basis of which recommendations for elimination are given. A module for receiving information from the locomotive's ALS was developed based on modern wireless technologies, and for the accuracy of checking the system, a stand based on the locomotive's ALS blocks for measuring signals was developed, which corresponded to the exact readings of the parameters of the ALS code signals. The developed module provides an opportunity to instantly notify the site's electromechanics of identified deficiencies in the ALS system.

“…In scenarios with very poor reliability, these systems are prone to errors when providing train traffic. Serious accidents and significant financial losses can result from even minor errors [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. In order to guarantee the safety of train movement, automation and remote control systems should have their level of safety inspected.…”

These days, automation and remote control technologies provide the foundation for the organization of train movement across several categories. At railroad sections and stations, dispatcher centralization systems are utilized to guarantee the security of train movement. However, in the railroad portions where high-speed train movements are organized, time limitations based on the human factor are being implemented. Consequently, this results in longer wait times for technological processes at stations and longer train intervals on some railway segments. Developing an automated route preparation procedure at stations in dispatching centralization systems will allow for the resolution of current issues. A dispatching centralized system model for route establishment has been created in this scientific study. Using a two-layer neural network, a mathematical model of route setting in the dispatcher centralization system was determined. Neural networks are employed in rail dispatch rooms for intelligent route comparison and in dispatcher centralized systems for tracking train routes at stations.
