Content and learning outcomes

Course contents

  • Simulation theory,  possibilities and limitations
  • Quality demand of the input and output in a railway simulation
  • Genomgång av olika simuleringssystem för tågtrafikanalys
  • Review of various simulation systems for train traffic analysis
  • Adaptation of infrastructure, vehicles and traffic in a common model
  • Presentation and use of the simulator RailSys
  • Various railway simulation approaches in line and network traffic applications
  • Delays; how they are detected, compiled and implemented
  • Construction of traffic operations, conflict resolution and adjustments for stable traffic arrangements
  • Analysis of the implemented simulations and reconciliation with reality

Intended learning outcomes

The course aims to provide an understanding of how and when railway simulation can be used and what its advantages and disadvantages are. The students should be able to perform simple simulations of train services on the Swedish rail network and from this draw conclusions about different kinds of conflicts between trains and the capacity of a railway line can be changed by varying the infra­structure, vehicles or traffic.

The students should after the course be able to:

  • Be able to use simulation as an analysis method
  • Explain the difference between reality and the simulated model
  • Explain the difference between macro and micro simulation
  • Be able to handle a specific railway simulator
  • Analyze different train time tables in terms of capacity and robustness

Course Disposition

The course consists of twelve days of lectures to teach the theory of simulation and computer time to learn a train traffic simulation program and to execute a variety of applied exercises. Examination is a smaller exam and some exercises to be reported.
