  1. 11. Urban freight transport sustainability - the interaction of urban freight and intermodal transport

    Author : Sönke Behrends; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modal shift; urban sustainability; transport planning; pre- and post haulage; rail freight; sustainable freight transport; Framework for Strategic Sustainable Development; urban freight transport; longer and heavier vehicles; intermodal road-rail transport;

    Abstract : Intermodal road-rail transport (IRRT) has a significant urban dimension that affects the environmental benefits and the modal shift potential of rail freight. A sustainable modal shift, i.e. READ MORE

  2. 12. Adhesion in the wheel-rail contact under contaminated conditions

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Yi Zhu; Ulf Olofsson; Ines Lopez Arteaga; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesion; wheel-rail contact; contaminants; rough surfaces;

    Abstract : Railway vehicles require a certain level of adhesion between wheel and rail to operate efficiently, reliably, and economically. Different levels of adhesion are needed depending on the vehicle running conditions. READ MORE

  3. 13. Light-weighting Methodology in Rail Vehicle Design through Introduction of Load Carrying Sandwich Panels

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : David Wennberg; Sebastian Stichel; Per Wennhage; Ragnar Larsson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sandwich panels; rail vehicle; lightweight; optimisation; carbody; TECHNOLOGY Engineering mechanics Vehicle engineering; TEKNIKVETENSKAP Teknisk mekanik Farkostteknik; TECHNOLOGY Engineering mechanics Construction engineering; TEKNIKVETENSKAP Teknisk mekanik Konstruktionsteknik; TECHNOLOGY Materials science Construction materials; TEKNIKVETENSKAP Teknisk materialvetenskap Konstruktionsmaterial;

    Abstract : Lightweight design in rail vehicles has been important for quite some time. Structures have been optimised to fulfill their purpose and cut unnecessary weight to reach allowable axle loads. Classically this is done by using steel, thin-walled structures, throughout the car body, or, alternatively, power-pressed aluminum profiles. READ MORE

  4. 14. On the Influence of Rail Vehicle Parameters on the Derailment Process and its Consequences

    University dissertation from Stockholm : KTH

    Author : Dan Brabie; Evert Andersson; Johan Oscarsson; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; train; railway; rail vehicle; accident; incident; derailment; bogie design; simulation; wheel; sleeper; impact; TECHNOLOGY Engineering mechanics Vehicle engineering; TEKNIKVETENSKAP Teknisk mekanik Farkostteknik;

    Abstract : 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.

  5. 15. The Internalization of External Effects in Swedish Transport Policy - A Comparison Between Road and Rail Traffic

    University dissertation from The International Institute for Industrial Environmental Economics

    Author : Lars Hansson; [1997]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Commercial and industrial economics; rail traffic; road traffic; transport policy; internalization; External effects; pricing-relevant costs; Industriell ekonomi;

    Abstract : Transport is a key factor for economic growth. It has enabled both the economic scale of production and an increase in competition. No one can question this role of transportation. There is, however, a back-side to the coin: the environmental challenge. READ MORE
