Analysis of the station’s track development load (according to the archives of railway switches and signal centralized systems)

Abstract

The development of equipment and technology of train operation, railway automation systems and new methods of train driving open the way for further intensification of train operation, reducing the time spent on standard operation procedures. Virtual coupling allows you to reduce a train-to-train interval. Automated schedules of the executed movement record performance of train operation, automate the formation of a train-dispatcher’s reports and delivery of orders to station attendants, allow timely detection of the causes of train delays and take appropriate measures. The points of growth in traffic intensity and volume could be in enhancing the level of intelligence of automation and telemechanics systems. Modern dispatch and electrical centralized systems contain archiving subsystems that store prompt train operation conditions and operator orders. But such data is used only when analyzing emergency situations - there is no systematic analysis of archive information to find hidden patterns and extract knowledge useful for optimizing the transportation process. In this paper, we propose a method for estimating the current train operation load of a railway station, and provide relative criteria for evaluating the actual load and algorithms for determining their numerical values. The analysis of the time series of the proposed criteria obtained for a single station equipped with a relay-processor centralized system is carried out. The analysis indicated a weekly cycle of train operation load of a station with good repeatability. The fact of reducing the speed of trains before the input signal in the through-pass routes with a preset route was revealed. Smoothing out the identified irregularities can positively affect the carrying capacity of a railway section as a whole.
