Railway Systems and Rail Vehicles

This course gives an introduction to railway systems and rail vehicles as well as examples on the rapid development in the field. The course is the only general railway course in Sweden.

The aim of this course is to give the fundamentals of the different parts of the railway system and to explain the possibilities and limitations of railway technology. The course also describes in more detail the components and functions of the vehicle. In addition, it covers the various demands a rail vehicle must fulfil.

Syllabus:

  •  Introduction to railway technology, organisation etc.
  •  Track constructions and track technology.
  •  Rail vehicles - overview.
  •  Rail vehicle dynamics and vehicle-track interaction.
  •  Electric train operation and pertinent stationary parts.
  •  Signal and traffic operation systems.
  •  Train traffic market, demands, terminals, planning and capacity.
  •  The railway and the environment: energy consumption, air pollutions, external noise, external vibrations, space and barrier aspects.
  •  Economy. Railway traffic development and future.
  •  Rail vehicles - technical basis.
  •  Aerodynamics and running resistance.
  •  Running gear, bogies and car body tilting. Traction technology: traction motors, transmission, traction mechanics and current collection.
  •  Braking technology.
  •  Car bodies.
  •  Passenger environment, interior design and auxiliary power.
  •  Internal noise, internal vibrations and climate resistance.
  •  Rail vehicle market and development.
  •  Exercises. Project task: to design a high speed train. Study visit.

Rail Vehicle Dynamics

This course deals with vehicle dynamics for rail vehicles, incl. interaction with the track. The topic has become increasingly important due to the need for faster and heavier trains.

The aim of this course is to give the fundamentals of rail vehicle dynamics and the dynamic interaction between vehicle and track.

Syllabus:

  •  Rail vehicle dynamics and interaction between vehicle and track.
  •  The track and the vehicle (in brief).
  •  Fundamentals of vehicle-track interaction.
  •  Some simple vehicle models and pertinent equations of motion.
  •  Eigenvalue analysis, transfer functions and other types of analysis.
  •  Models of wheel sets, bogie frames and car bodies.
  •  Geometry and guidance for wheel set and track.
  •  Creep (sliding), creep forces (friction forces), ride stability and curve negotiation.
  •  Track forces. Safety against derailment: wheel flange climbing, vehicle turnover, rail turnover.
  •  Wheel and rail wear.
  •  Ride comfort. Vehicle gauging.
  •  Examples on different vehicles' dynamic interaction with the track.
  •  Simulation and measurement in practise.
  •  Exercises. Assignments. Project task (computer work): simulation of dynamic interaction between rail vehicle and track. Study visit.
