  1. 6. ERTMS - approximation av lutningar för högre kapacitet på järnvägsnätet

    Kandidat-uppsats, Lunds universitet/Utbildningar i Helsingborg

    Författare :Jan Näpärä; John Pettersson; [2012]
    Nyckelord :ertms; etcs; gsm-r; lutningar; approximation; järnväg; ådalsbanan; signalsystem; gradients; railway; signalling; Technology and Engineering;

    Sammanfattning : Ådalsbanan, an existing railway-line in northern Sweden, is a line that has been upgraded from the current Swedish signaling system, ATC, to the new standard in Europe, ERTMS. While the upgrade was ongoing there was a problem discovered, there were too many gradients on the line for the system to handle. LÄS MER

  3. 7. Is GSM-R the limiting factor for the ERTMS system capacity?

    Uppsats för yrkesexamina på avancerad nivå, KTH/Trafik och logistik

    Författare :Gustaf Lindström; [2012]
    Nyckelord :;

    Sammanfattning : The European Rail Traffic Management System, ERTMS, is introduced as a common signalling system for the European railway network. ERTMS consist of two main parts, the signalling part ETCS and the radio transmission system GSM-R, based on the well-established GSM standard. LÄS MER

  4. 8. On Models for Interference Calculations between Radio Communication Systems

    Uppsats för yrkesexamina på avancerad nivå, KTH/Signalbehandling

    Författare :Fredrik Vihlborg; [2011]
    Nyckelord :;

    Sammanfattning : When installing a new radio system, it is of great importance to know that it will not interfere with the already existing systems, and that they can coexist side by side. The problems that will follow if interference occurs, can be of huge magnitude, e.g. radars not working, trains stopping etc. LÄS MER
