Investigation of the influence of railway system parameters on track capacity

Stergidou, Anastasia
Pyrgidis, Christos

The present study investigates the effect of various parameters of the track, the rolling stock and the operation and exploitation conditions on track capacity, calculated by the method proposed by the International Union of Railways (U.I.C.), using an appropriate simulation model. Some of the parameters taken into consideration include the length of the critical track subsection, the average running time of passing trains, the level of service, the existence and positioning of an intermediate block signal within the critical track subsection, the degree of traffic uniformity etc. For all of the examined parameters, variation charts of track capacity and track saturation ratio were extracted, for both the cases of operation: track with one-way traffic and track with bi-directional traffic. The analysis showed that the parameter that mostly affects track capacity is the level of service, expressed as the buffer time taken into consideration after each train’s departure, in order to avoid additional delays. Also, the length of the critical track subsection and the average running time of passing trains have a significant impact on track capacity. Finally, it was proved that the existence of an intermediate block signal within the critical track subsection can lead to an increase of up to 43% in track capacity.
