Courses at TU Dresden/Germany:
Railway Systems and Rail Vehicles
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

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
- Rail vehicle dynamics and interaction between vehicle

- 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
- Geometry and guidance for wheel set and track.
- Creep (sliding),
creep forces (friction forces), ride stability and curve negotiation.

Basics of rail vehicle engineering
- Characterisation and classification of rail vehicles
- Regulations and derived calculation parameters
- loading gauge calculation
- Basic materials in rail vehicle manufacturing
- Push- and pull equipment
- Special equipment for rail vehicles
Rail vehicle brakes
Starting from operational demands concerning rail vehicle brakes
to ensure safe operation, theoretical basics about dimensioning
and evaluating of braking systems have been imparted.
Gaul of this course was to learn the basics and to handle the
dimension of drive and transmission systems as well as other
equipment of diesel driven power units.
