11. Rail Tunnel Evacuation
Sammanfattning : In this thesis, human behavior in rail tunnel fires is explored. Descriptive knowledge is presented related to the evacuation of passenger trains, and the subsequent tunnel evacuation to a safe location. LÄS MER
12. On the Influence of Rail Vehicle Parameters on the Derailment Process and its Consequences
Sammanfattning : This thesis aims at systematically studying the possibilities of minimising devastatingconsequences of high-speed derailments by appropriate measures and features in thetrain design, including the running gear. The course of events immediately afterderailments is studied with respect to whether the train stays upright and close to thetrack centre line or deviates laterally with probably serious consequences.

13. Delays and Timetabling for Passenger Trains
Sammanfattning : Travel by train has increased steadily in Sweden the last 30 years. The pace has been about two to three percent per year, and we now have twice as many passengers. With growing awareness of the changing climate, the pace is increasing further. A problem that affects both passengers and businesses in Sweden is train delays. LÄS MER
14. Evaluation of passenger train concepts : Methods and results of measuring travellers' preferences in relation to cost
Sammanfattning : Politicians would like the railways to help to solve futuretransport and environmental problems. People can travel to andfrom work and on business during the day on modern trains whichare faster than any other alternative on journeys ofintermediate length. LÄS MER
15. Noise from Train Cooling Fans
Sammanfattning : This thesis concerns a study undertaken on a railway vehicle cooling fan system. Several design modifications were proposed and tested in the laboratory in order to evaluate different noise control measures. The most effective noise control measure involving combining lots of different measures gave 7 dB(A) noise reduction. LÄS MER
