“…With the statistical regression algorithm, they successfully predict the location of the damage in advance 10 Mt (million tons) of the traffic volume and determine the state of the crossing nose. Vadim Korolev solve the issue of safe permissible dimensions of a gauge track and flangeway gap [16]. His team also reduce maintenance expenditures on curved turnouts and increase the travel speed through turnouts up to the ones when rounding a curve [17].…”

The share of rail transport in world transport continues to rise. As the number of trains increases, so does the load on the railway. The rails are in direct contact with the loaded wheels. Therefore, it is more easily damaged. In recent years, domestic and foreign scholars have conducted in-depth research on railway damage detection. As the weakest part of the track system, switches are more prone to damage. Assessing and predicting rail surface damage can improve the safety of rail operations and allow for proper planning and maintenance to reduce capital expenditure and increase operational efficiency. Under the premise that functional safety is paramount, predicting the service life of rails, especially turnouts, can significantly reduce costs and ensure the safety of railway transportation. This paper understands the evolution of contact fatigue on crossing noses through long-term observation and sampling of crossing noses in turnouts. The authors get images from new to damaged. After image preprocessing, MPI (Magnetic Particle Imaging) is divided into blocks containing local crack information. The obtained local texture information is used for regression prediction using machine-supervised learning and LSTM network (Long Short-Term Memory) methods. Finally, a technique capable of thoroughly evaluating the wear process of crossing noses is proposed.

This paper presents a direct calculation of the average value of defective elements of point products. Production process control is considered using the example of the control of point products. The calculation of the first four moments in a binomial distribution of the number of defective elements of point products is made. The standard error of the fraction of defective elements is considered in detail.

Statistical methods of control of point components and quality of point products are an integral part of modern point production, and their application is closely connected with solving tasks of increasing labour productivity and general enterprise culture, saving materials, and reducing defects. The paper presents a derivation of basic formulas for a binomial distribution of elements of the railway track superstructure. Calculation of theoretical distribution is made. The interrelation between probability theory, statistics, and quality control of point products is considered.
