With the increasing demand on train trips, shortages of train services are experienced, especially in the parts of the world where urban development is fierce. Operational measures to improve railway capacity are considered the most economically viable way to tackle the issue. Though of central importance in railway operations, the problem of capacity analysis was never perfectly solved. The famous UIC compression method suggested by the International Union of Railway was studied by its various related aspects, and several shortcomings have been laid bare by publications known to the community. The analytic method adopted in the SLS software family (which is officially used by Deutsche Bahn AG) produces results with and without a ready timetable. However, it is noteworthy that the result is imperfect, which can be told from the fact that two timetables the clearly differ result in the same value of capacity usage. This is due to over-simplification in its defined computational procedure. Stemming from these facts, this thesis intends to pool efforts into improving the method for railway capacity analysis. Firstly, the UIC compression and SLS methods are briefly analyzed from a methodological perspective, which gives the insight on their approximating nature. Secondly, the methods to compute the separation of train paths are studied, and the concrete computational details are given and analyzed, since this is unavoidable for any method to give a complete description of infrastructure utilization by train operations. Then, it becomes clear that the calculation process of UIC compression and SLS methods amounts to formulate a graph in the shorter sections resulting from their respective dividing procedures. In this regard, we see that such a graph for shorter section is a subgraph of the whole section of interest. Finally, heavily capitalizing “Zacken-Lücken-Problem”, an algorithm is given to compute all the required details to formulate such a graph of the whole infrastructure, which is called infrastructure ...
