  1. 1. Feldetektering i återgångkablar

    Kandidat-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Erik Asp; [2021]
    Nyckelord :Feldetektering;

    Sammanfattning : The purpose of ths report is to shed light on the problems surrounding error detection in returncables, specifically in connection with tunnels. In Sweden, among other things, has chosen to usea BT system with a suction transformer and a dedicated return conductor to reduce interferencesuch as occurs on telecommunications and signal cables along the track.

  4. 3. The Resilience of the Rail System for International Freight in Öresund Region in Case of Major Disruptions

    Master-uppsats, KTH/Transportplanering

    Författare :Sneha Gosavi; [2021]
    Nyckelord :Öresund Fixed Link; Capacity constraints; Freight trains; Simulation; Fast förbindelse Öresund; Kapacitetsbegränsningar; godståg; simulering iv;

    Sammanfattning : Rail Transport has held an important place in the European economy. Several problems plague rail freight. We frequently hear about train disruptions, whether it is due to a signal failure or an infrastructure breakdown, most of which have caused significant issues for both passengers and cargo. LÄS MER

  5. 4. The impact of the Fehmarn Belt link on modal choice - An investigation of potential modal shift on Sweden’s foreign trade

    Master-uppsats, Göteborgs universitet/Graduate School

    Nyckelord :Cross-border barriers; Fehmarn Belt tunnel; Intermodality; Modal choice; TEN-T;

    Sammanfattning : The construction of the Fehmarn Belt tunnel is a part of the European Union programme called TEN-T. A programme with the objective to connect the EU member-states in a comprehensive network consisting of road, rail, air and water infrastructure. LÄS MER

  7. 5. Simulation of air quality in underground train stations

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Benjamin Söderberg; [2020]
    Nyckelord :PM10; aerosols; air pollution; particulate matter; emission factors; underground train station; PM10; luftkvalité; tåg; emissionsfaktorer; underjordiska tågstationer;

    Sammanfattning : Particulate matter (PM) is a widespread air pollutant of microscopic particles that are suspended in the atmosphere. There is high concentration of PM in underground train stations and tunnels. The concentration of particulate matter (PM10) measured in Stockholm’s metro varies significantly between day and nighttime traffic of trains. LÄS MER
