Abstract [en]

The demand of rail travel and transport of goods by train has increased significantly in Sweden during the last decades. Due to the high utilisation level, significant capacity shortages is nowadays common on numerous lines within the railway system causing substantial delays and low punctuality. The demand is foreseen to continue to increase, especially since we live in a time of climate change and travelling by train is an environmentally sustainable alternative.

The government of Sweden has initiated an investigation of potentially building a high-speed railway connecting Stockholm with Malmö and Gothenburg. This would reduce the strain on existing railways, but it would also demand large investment costs and the subject has therefore been highly debated in politics and by media. The purpose of this study is to investigate potential future high-speed train stations between Jönköping and Malmö. The route of the track has not yet been decided but Växjö and Värnamo are the two primarily discussed cities for a station along the route. This study therefore focuses on studying the capacity and robustness of these two stations but also for a potential high-speed train station.

By developing event-based models of the stations in SimEvents, which is a simulation tool in Matlab, the trains and their movements could be visualized and studied. The capacity of Växjö and Värnamo station were simulated with different track formation and diverse track dedication. The theoretical capacity as well as different forecasted timetables for the year of 2040 was simulated for the stations and the results showed that the station in Värnamo has greater potential in dealing with future demand without needing costly refurbishments.

One infrastructural solution was created for the highspeed train station according to Trafikverket’s technical specifications. The maximum speed for the railway switch was set to be 130 km/h since it was calculated to be the lowest possible speed to maintain the specified headway. A switch that could handle higher speeds would result in greater capacity of the station but in addition greater investment costs. The results from simulating the high-speed station emphasised the importance of homogenous traffic. It was also seen that it is easier to remain high robustness when there is a small number of great delays than if the system is exposed to multiple small delays.
