Research areas

KTH Railway Group performs research within several disciplines.

Efficient train systems for freight traffic

Green Cargo

The research within efficient train systems for freight traffic aims at developing methods and contributing to knowledge to make trains more attractive for transport customers, and more profitable for the train companies. Cost-effective solutions with new technologies and new transport and logistics arrangements contribute to relieving the road network and to strengthen the competitiveness of the railway.

Sound and vibrations

Ljud och vibrationer

The research within sound and vibrations aims at treating related problems in railway engineering. A good environment for people on the train puts high demands on the sound and vibration environment in the vehicles. Society's demands for low noise disturbance require trains with low noise emission. Further, an environment in which vehicles, track and transported goods are not damaged requires low vibration levels.

Vehicle engineering

Fordonsteknik

The research within vehicle engineering aims primarily at studying and improving the dynamic interaction between the rail vehicles and track. Examples of aspects are derailment risk, running stability and ride comfort as well as wear and fatigue of wheels and rails. Meanwhile, there is strong desire for heavier freight trains and faster passenger trains. The studies are based on sophisticated computer simulations and field measurements.
