On the issue of improving the accuracy of calculating the capacity of the switch necks

The article deals with an urgent issue related to improving the accuracy of calculating the capacity of railway transport facilities. To solve this problem, the authors have proposed a new approach to determining the loading of switch throat – in addition to the occupation of movement and scheduled maintenance, the developed algorithm will take into account structural (technological) losses. The essence of the algorithm is an element-by-element analysis of the occupation of switch groups – time intervals are considered when the switch was not actually occupied by movement, but could have been occupied if no incident had occurred. Using the method of simulation modeling on real objects, the verification of the new approach was carried out. A new approach was verified using the simulation method on real objects. A comparison of the results obtained using various calculation methods is provided: analytical (according to the current Instruction of JSC Russian Railways No. 545/r), model-based, and model-based calculations using both the model and the proposed algorithm.
