CORRIDOR 10 - a sustainable way of integrations
1. INTRODUCTION
Ljubljana railway station is located at the crossing of X. and V. Pan-European corridors passing
through the territory of the Republic of Slovenia. All railway lines linking North, South, East and West
of Slovenia pass through the Ljubljana station. Disruptions of traffic ensuing from a construction work
at the Ljubljana station have impact on traffic flow on the entire Slovenian railway network and beyond.
Additionally, disruptions affect the capacity of corridors meeting at the node (station). The planned
construction activities at the Ljubljana station will bring about traffic disruption (e.g. train delays) on the
entire railway network. A well-selected and planned construction technology and according traffic
operation technology conception during the construction works at the Ljubljana station is essential for
control and limitation of traffic disruption. Major construction works are planned at the Ljubljana
station, which will increase station and traffic flow capacities and allow implementation of
supplementary passenger services at the station area (shopping mall). The works will be phase-run,
each putting some restriction of exploitation of available station transport infrastructure; therefore it is
necessary to conceive a train operation phase-wise.
Conception of train operations during the infrastructure possessions or planned slow runs is generally
supported by several software tools. RailSys is one of them that excelled in several notable transport
studies. The tool is comprised of several modules and functions. A micro-simulation module that we
will discuss in the paper allows design and simulation-tests of train operation during restrictions
entailed by planned possessions or downtime in specific infrastructure elements in order to provide
optimal train operations in terms of set criteria. The results show level of resolving of delays and
conflicts between the train paths as well as optimal track occupancy during the construction works.
2. ELABORATE ON RAILWAY TRAFFIC OPERATIONS DURING CONSTRUCTION WORKS
Construction works on railway infrastructure under operation impacts change of regular trains’
operation. Design of trains’ operation is elaborated in the “Elaborate on railway traffic operations
during constructions works” Contents of this elaborate are governed by Slovenian legislation:
- technical and organisational measures,
- costs induced by delays of passenger and freight trains,
- costs of alternative transportation,
- costs of organisation of infrastructure possessions,
- costs of additional man-power requirements,
- other costs.
All indicated and required information can very effectively and precisely be produced using RailSys
simulation software as described in the following.
“Elaborate on railway traffic operations during constructions works” is an integral part of design and
technical documentation that is required for acquisition of building permit.
3. RAILSYS – TRAIN OPERATION SIMULATION SOFTWARE TOOL
3.1 About RailSys software
RailSys software provides integrated management of timetable paths and infrastructure data for the
entire planning and operations process. RailSys software has the following system components:
