The operating intervals and the intervals of subsequent rides are among the basic (normative) elements of the train transport schedule. These intervals are designed to control train movements and ensure the smooth running of trains with regard to safety and other operating regulations.
Run intervals are used for the construction of the train traffic diagram, for the control of train movements and for the design of the railway infrastructure. They are also used to calculate the permeability of railway lines according to a special regulation.
The operating intervals must be determined as precisely as possible. Their correct determination, as well as their observance, is a basic prerequisite for ensuring smooth transport operation. The operating intervals are set for stations and, for their separate parts, such as personal, entrance, exit groups, etc.
From 9th of December, 2017, a new rule for calculating slots has been applied to the ŽSR network. The rule gives the possibility to calculate and apply new service intervals since GVD 2019/2020. The direct application of these new operating intervals changes and adjusts work in individual stations.
In the present article, new service intervals will be calculated with direct application on the Žilina - Rajec railway line. At present, some operating intervals are not taken into account in the construction of the GVD. Subsequently, stressful situations are being experienced by executive employees in everyday situations. Due to the width of the area surveyed, this paper will only mention the calculations of the operating intervals for the Bytčica railway station.
