FSD3307 Rail Vehicle Technology 7.5 credits

Introduction to railway technology. Track technology. Rail vehicles - overview. The railway and the environment: energy consumption, air pollutions, external noise, external vibrations. 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, development, and social and environmental sustainability related aspects in relation to electric mobility.

The course gives a short introduction to railway systems and then focuses on rail vehicles.

The course aim is to give you the fundamentals of railway systems and, in particular, to describe the components and functions of rail vehicles as well as the various demands a rail vehicle must fulfil. The course should give you a good platform for work in the field of railway engineering.

After a completed course you should be able to:

• clarify the different parts in railway systems and their possibilities and limitations
• explain how bogies, carbody tilting, traction and brake systems work and can be improved
• calculate train performance like acceleration and braking capacity, average speed and energy consumption
• determine outer dimensions and interior design for a train at a given operational task
• discuss the trends and future potential for railway traffic and their influence on advancing social and environmental sustainability and sustainable transportation.
• carry out detailed analysis of a specific area within rail vehicle technology

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

If the course is discontinued, students may request to be examined during the following two academic years.
