    Research output: Contribution to journalJournal articleResearchpeer-review


    Many capacity analyses using the UIC 406 capacity method for double track lines have been carried out and presented international, but few capacity analyses applying the capacity method to single track lines have been presented. Therefore, the differences between capacity analyses of double track lines and single track lines are discussed in this article. The principles of the UIC 406 of double track lines can be applied to single track lines-at least when more than one train follows each other in the same direction. In a presentation of the UIC 406 for single track operations, it is important to define where to divide the railway lines into line sections and how the conflicts between trains at crossing stations and junctions have to be analysed. The effects on railway networks with single track lines and their impact on capacity consumption are described to enable a consistent capacity statement.
