Abstract
Analysis of rail capacity
- Investigation of capacity limits Västkustbanan was first recognized by the Swedish Parliament over 50 years
ago, when it was decided that the entire route would be equipped with phased
out double-track extension. The main purpose was to cope with the future
traffic development, along the railway corridor. Since the decision was made,
the phased out double-track extension is nearly 85 percent complete.
Remaining track stages for future extension is: Varberg, Hallandsås and the
track between Maria-Ängelholm. These are included in the government-defined
action plan for the transportation system, which forms the essential for
how Trafikverket will provide funding for new investments in the Swedish

Analysis of rail capacity
- Investigation of capacity limits Västkustbanan was first recognized by the Swedish Parliament over 50 years

out double-track extension. The main purpose was to cope with the future
traffic development, along the railway corridor. Since the decision was made,
the phased out double-track extension is nearly 85 percent complete.
Remaining track stages for future extension is: Varberg, Hallandsås and the
track between Maria-Ängelholm. These are included in the government-defined
action plan for the transportation system, which forms the essential for
how Trafikverket will provide funding for new investments in the Swedish
railway. The action plan also initiated that during the plan period, a new
double-track between Förslöv and Ängelholm would be done and also various
tunnel connections through Hallandsås, Helsingborg and Varberg. In addition
to these segments, a double-track development begins between Maria and
Ängelholm and an underground tunnel through Gothenburg, entitled
Västlänken. Once these stages have been completed, the travel time with the
current Öresundståg can be reduced by half an hour from Gothenburg to
Malmö, according to Skånetrafikens calculations. However, the remaining
route section between Maria and Helsingborg are still single-tracked.
For the upcoming plan period that extends beyond 2021, the Swedish transport
administration, Trafikverket requires a new base of planning and knowledge,
where this study will highlight the measures that ensure a better utilization of
capacity in the existing infrastructure corridor of the 2028th. This thesis has
therefore sought to increase the knowledge, about the limit of capacity for
Västkustbanan and and how this capacity can be optimized for passenger
transport with regard to freight work. The study was conducted using
modeling of infrastructure and timetabling with the software RailSys, which is
a tool for traffic simulation and timetabling. The study of timetable is based on a model whose infrastructure is developed
by the authors, on the standards of an existing model with the infrastructure
corridor of the 2011th, provided by Trafikverket. Additions have been added
to the model with the infrastructure that is enshrined in the action plan, for the
transportation system. The main purpose of this model is, that it should give a
representative picture of the transportation system of the year 2028 and thus
forms the basis for analysis. The results of the timetable planning has shown that the infrastructure
expansion, that are scheduled to be complete in year 2028 provides improved
capacity and reduced travel times for Västkustbanan. The analysis of the
timetable planning is conducted with a focus on promoting the long-range
regional transport, with a high-speed performance train, which then becomes
relieved by a short-distance regional train as well by a local shuttle service.
The existences of the racing effect that occur in the transportation system are
based on the three different types of trains, which are used with different
speed and functions. The use of different train types implies that travel times
are prioritized over capacity, since the gains from travel time may justify the
use of three train types. The timetable analysis in this thesis has shown that an increase of frequency
from the current quarter traffic, to five trains per hour is feasible for the local
Kungsbacka shuttle, largely thanks to its ability to separate the trains after
Almedal. It is then necessary that the inter-regional train without stopping at
in-between stations operates in today’s central station in Gothenburg.
In particular it underlines the scheduled timetable the benefits with a highspeed
train, this type of train have a contribution to track capacity every hour
during peak traffic between Gothenburg and Lund. The main gain is the
reduced travel time of 65 minutes compared with today’s traffic with
Öresundståg. The study has also highlighted the need for improvements in the infrastructure
for increased track capacity. A significant bottleneck in the system is the
single-track segment between Maria and Helsingborg. In addition there is a
need for additional bypass opportunities, by expanding the siding on selected
operating locations or increase to four tracks. The conclusion is that planned infrastructure improves the capacity to a fairly
small degree, but offers greater travel times and potential for enhanced
capacity through further improvements. (Less)
