Modeling railway line capacity on Karabuk - Zonguldak line

In this study, passenger train operation on the single track railway on the Karabuk-Zonguldak track was examined. A solution was sought for the problems related to waiting and delays on this railway line and the optimum tariff was tried to be found. In the study, "daily train capacity" that can be operated on the Karabuk-Zonguldak line, where 10-station and 8 daily passenger trains with both directions are operating, was examined and a particle swarm optimization (PSO) based programming model was applied. In this model, the track of 116.6 km between Karabuk and Zonguldak is considered. The simulation study of the proposed method was carried out with the MATLAB program. As a result of the modeling, according to the data provided, the train departure times were rearranged and it was demonstrated with the simulation that 65% improvement was achieved in delays.
