The Analysis Of Congested Infrastructure And
Capacity Utilisation At Trafikverket
Author(s)

Abstract
The capacity utilisation in the Swedish rail network remains constantly high. The
competition between approximately forty different railway operators applying
for timetable slots continues. Trafikverket performs analysis of the railway
capacity with different methods and tools. The calculation of the capacity
utilisation is performed annually for the entire railway network. It is based on a
common European standard described in the Capacity Leaflet UIC 406. This
paper presents the implementation of this method in Sweden as well as the recent
results. Trafikverket has, during the annual capacity allocation process, since the
year 2007 declared different sections of the network congested. The capacity of
congested sections is then analysed in order to find solutions for capacity
shortages. Trafikverket performs timetable analysis with the tool TrainPlan and
simulations with the tool Railsys. Trafikverket investigates the timetable
robustness, calculates headways between trains operating on the double track and
defines some guidelines for traffic planners.
The Southern Main Line that connects the first and third biggest cities in
Sweden- Stockholm and Malmö- has been congested during 2011. This paper
presents the variety of methods used while analysing this congested line. In
particular, the cooperation with Linköping University within the field of
punctuality and timetable robustness is mentioned here, with particular focus on
the punctuality studies of the Southern Main Line.
