The activities at the Division of Rail Vehicles focus on rail vehicles and their dynamic interaction with the track and on general questions on railway system efficiency.
The division is one of eight members of the KTH Railway Group.
Today considerable investments are made in railway systems in many countries. For example, in Europe high-speed rail nets are built and new attractive rail vehicles are introduced. It is expected that rail traffic will constitute an important part of an integrated transport system for a sustainable and low-resource society.
Considerable changes are to be expected within the next, say, ten years. Travel and transport times will be halved in many cases. Passenger train frequency will increase and the trains will be more attractive. The freight traffic will also improve. The rail infrastructure will be developed in fields like information technology, signal systems, traffic control etc.
Rail vehicle development will result in higher top speeds (>300 km/h) and average speeds (> 200 km/h). Active suspension will be more common in the vehicles. Sound and vibration levels for passengers and people living nearby will be reduced. Light-weight materials and new traction systems will be used. Energy consumption and air pollution will continue to be small, in spite of the increasing speeds.
