The Capacity of Conflict Points Between Double-Track Lines

The objective of the railway is to offer high level of transport services, i.e. the quality which is competitive to other transport modes, but which minimises its internal costs at the same time. In order to increase the capacity of transport services and reduce the costs, splitting of trains between different categories of transport on separate railway lines will be more and more applied in the 21st century. Unfortunately, even in the developed countries there will be lines or line sections where mixed traffic will be carried, and in developing countries this will often be the case even on the main trunk lines. Therefore, a topical issue is to establish the capacity and choose the right solution. The problem becomes more complex in cases when two double-track lines with mixed traffic need to be connected and the restructuring of traffic implemented. At the same time the exits to two new double-track lines with the specific train categories have to be ensured and the required quality of transport services maintained. In this paper, the impact the capacity has on quality is discussed and some basic characteristics of a model, which enables the research of the conflict points capacity, i.e. of converging and diverging points of two double-track lines is given. Although, there are some analytical elements in this model, it is essentially simulation which enables us to carry out tests under different conditions, to study different variants and to systematise different indicators and make conclusions.
