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

    Author : Sönke Behrends; Chalmers tekniska högskola; []
    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

  4. 2. The Influence of Customer Agreements and Planning Principles on Rail Freight Performance

    Author : Lars Backåker; Lundgren Jan; Johanna Törnquist Krasemann; Stefan Engevall; Markus Bohlin; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Rail freight planning; trip plan generation; routing and scheduling; dynamic assignment;

    Abstract : Rail freight transportation is recognized worldwide as a suitable transportation mode when it comes to long haul transportation of heavy commodities. The industry is also known to be capital intensive, highly dependent on infrastructural developments and requires thorough planning of operations. READ MORE

  5. 3. Simulation Studies for Improved Efficiency in Road and Rail Freight Transports

    Author : Ingrid Johansson; Markus Bohlin; Oskar Fröidh; Behzad Kordnejad; Carl-William Palmqvist; C. Tyler Dick; KTH; []

    Abstract : The demand for road and rail freight transport continues to grow with the expanding economy, while the climate crisis requires reduction in greenhouse gas emissions. Therefore, tools and solutions for reducing fossil fuel use and enabling more efficient use of infrastructure are needed. READ MORE

  6. 4. Long freight trains and long-term rail surface damage

    Author : Visakh V Krishna; Sebastian Stichel; Mats Berg; Carlos Casanueva; João Pombo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; track friendliness; rail surface damage; multi-body simulation; longitudinal train dynamics; track maintenance; rolling contact fatigue; wear; Engineering Mechanics; Teknisk mekanik; Vehicle and Maritime Engineering; Farkostteknik; Järnvägsgruppen - Effektiva tågsystem för godstrafik; Järnvägsgruppen - Effektiva tågsystem för godstrafik;

    Abstract : Track damage due to progressively increasing tonnage, especially due to longer and heavier freight trains, is one of the major problems faced in the European rail sector. In this context, to stay competitive, optimal track maintenance practices, track-friendly vehicles and safe operations of long freight trains assume prominence. READ MORE

  7. 5. Effects of top-of-rail friction modifiers on the friction, wear and cracks of railway rails

    Author : Saad Ahmed Khan; Jan Lundberg; Rolf Dollevoet; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : The railway is an economical and environmentally friendly mode of transport for long distances and heavy loads. The demands on the operators are increasing with increased competition in the market, and therefore they are currently demanding more track capacity. In the short term, the existing network is expected to deliver the increased capacity. READ MORE
