Title:
Resource efficient rail transport systems: A railways perspective to REV

Abstract:
Railway Transport is already today in several aspects a resource efficient transport system. It is very energy efficient, has low CO₂ emissions since it is easily electrified, has a high transport capacity in relation to the land use, and it is very safe. Nevertheless, researchers and vehicle manufacturers are working on further reducing energy consumption and emissions from rail vehicles with e.g., lightweight designs, reduced air drag or novel and optimized propulsion systems. Also, the infrastructure, is a very important an integral part of the system, where construction of new railway lines leads to substantial CO₂ emissions in the building phase. Ongoing developments will be shown in the presentation. Another possible contribution to a more sustainable transport system is to change the modal split, i.e., to increase the share of rail transport as part of the whole transport volume, which is propagated for example by the EU. To increase the share of railway transport, it must be made as attractive and cost efficient as possible. Thus, in the presentation aspects of a more attractive railway system will be discussed as well.
