    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shunting yards; delay prediction; congestion; delay probability distributions; temporal delay distributions; Rangergodsbangårdarna; förseningsprediktion; trängsel; fördröjning av sannolikhetsdistributioner; tidsfördröjningsdistributioner; Transportsystem; Transport Systems;

    Sammanfattning : The European Commission has foreseen a modal share of 30% by 2030 for rail freight transport. To achieve this increase in the modal share, enhanced reliability of rail freight services is required. Optimal functioning of shunting yards is one of the areas that can improve this reliability.

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shunting yards; train delays; machine learning; simulation; freight transport; Godsbangårdar; tåg förseningar; maskininlärning; simulering; godstransport; Transportsystem; Transport Systems;

    Sammanfattning : Increasing the modal share of rail freight transport is one of the main ways to achieve carbon neutrality in Europe. The perceived low reliability and predictability of rail freight services is one of the main challenges to overcome in reaching this target. LÄS MER

  4. 3. Evaluation of test cycles for freight locomotives

    Författare :Mattias Skoglund; Stefan Östlund; Peter Thelin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; duty cycles; test cycles; diesel locomotives; locomotive emissions; dual modes; hybrid systems;

    Sammanfattning : Diesel locomotives provide versatility to the railway system as they do not depend on electric feeding. Worldwide they constitute important parts of locomotive fleets used for various tasks such as mainline services, shunting and terminal operations. The main drawbacks are emissions of CO2, NOx and other pollutants. LÄS MER

  5. 4. Mathematical models for optimising decision support systems in the railway industry

    Författare :Sara Gestrelius; Johanna Törnquist-Krasemann; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : After the deregulation of the Swedish railway industry, train operating companies compete for and on the same infrastructure. This makes the allocation of rail capacity a most delicate problem, and for a well-functioning railway system the allocation must be fair, efficient and functional. The capacity allocation tasks include e.g. LÄS MER

  7. 5. Shunters at work : creating a world in a railway yard

    Författare :Birgitta Edelman; Tim Ingold; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social anthropology; Socialantropologi; Social Anthropology; socialantropologi;

    Sammanfattning : Skills, and particularly manual skills, are often seen as acquired through unquestioning practice and drill. This is an ethnographic account of a group of railway workers, called shunters, who are occupied with the manual task of assembling carriages into trains. LÄS MER
