Tilting trains: description and analysis of the present situation
Swedish National Road and Transport Research Institute, Traffic and road users, Human-vehicle-transport system interaction.
2007 (English)Report (Other academic)
Abstract [en]

This report is divided in two main parts, the first, chapters 2 to 7, covers knowledge found in the literature study. The two first chapters in the literature study give a description of concept of, and a state of the art report on, tilting trains. Development trends are identified and reported. The next two chapters report on track and the interaction between track and vehicle. Cross-wind stability is identified as critical for high-speed tilting trains and limitation of allowed cant deficiency may be needed, reducing the benefit of tilting trains at very high speed. The second last chapter in the literature study deals with motion sickness, which may be important for the competitiveness of tilting trains. However, reduced risk of motion sickness may be contradictory to comfort, one can not be considered without also considering the other. The last chapter in the literature study report on winter problems connected to tilt and/or high speed, which essentially can be divided in ballast stone lift and snow packing. The mechanism of stone lift is described and countermeasures are identified. Snow packing on tilting trains is reported to have a relation to safety critical issues that must be mitigated. Chapters 8 to 10 covers analysis made within this study with the aim to identify areas where research can improve the competitiveness of tilting trains.
