Internal noise, internal vibrations and climate resistance. Rail vehicle market and development. Exercises. Project task: to design a high speed train. Study visit.

Intended learning outcomes *

The course aim is to give you the fundamentals of the different parts of the railway system and their properties. The course also describes in more detail 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 the tracks, signal safety systems and electrification work and can be improved
• design a time table for train traffic on a given railway line
• 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 realistic measures and interior design for a train at a given operational task
• estimate the incomes and costs for a given train traffic concept
• discuss the trends and future potential for railway traffic
