Railway electrical traction simulator


The railways system is, in any country, one of the key columns of the land transport for passengers and goods. The architecture of a national railway structure is a complex system, that includes many interrelated technical disciplines. Such complexity leads to consider Railway engineering as a specialized branch of engineering itself (usually regarded as a post-graduate discipline). The Simulator has been specifically designed to study the fundamentals of train dynamics. The student will be able to test what learnt in theory by modifying different parameters of the system and visualizing the effects on the train dynamics.

Training program

Railway traction analysis:

  • General concepts
  • Motion resistance in straight paths, with no bends nor slopes (the Davis formula): mechanical motion resistance (independent from the train speed), speed-depending motion resistance and squared-speed motion resistance (aerodynamic resistance)
  • Motion resistance in bends
  • Motion resistance in slopes
  • Motion resistance due to rotating masses
  • Traction and braking forces
  • Deepening on braking: service braking system and emergency braking system. Calculus of the distance and time required for a complete train stop.
  • Wheel-track friction factors. The adherence force and the required necessary and sufficient conditions for the train motion
  • Traction and total motion resistance forces curves as a function of the train speed. Motion limits imposed by the vehicles
  • Examples of the theory application on real trains configurations
