Entry requirements

120 credits in science/engineering, of which at least 10 credits in Electrical Engineering. Proficiency in English equivalent to the Swedish upper secondary course English 6.

Learning outcomes

After passing the course, the student should be able to:

• calculate acceleration, braking forces, energy consumption and losses for trains and trams,
• make quantative assessments on limitations for railway systems,
• critically analyze electric railway systems and their interatction with other operators in public transport systems,
• describe railroad safety systems and their signal systems.

Content

Components and their function in an electric railway system, including track, rolling stocks, onboard equipment, pantographs and booster transformers. System capacity and its dependency on speed, departures per minute, distance between stations, and other factors that affect the number of ppassengers per hour. Dynamic models depending on speed, slope, turning radius, etc. for train, metros and trams. Rolling stock dynamics and forces between wheel and track, power demand, drag and braking power. Safety and signalling system.

Instruction

Lectures and seminars.

Assessment

Active participation in seminars (1 credit), oral and written assignment (2 credits).

If there are special reasons for doing so, the examiner may make exceptions from the specified examination method of assessment and allow a student to be assessed by another method. An example of special reasons might be a certificate regarding special pedagogical support from the disability coordinator of the university.
