  1. 11. Metodik för att effektivisera arbetsprocessen av ombyggnad av tåg med ETCS utrustning. : Anpassning av svenska fordon.

    Master-uppsats, KTH/Trafik och logistik

    Författare :Hussein Alsharifi; [2014]
    Nyckelord :;

    Sammanfattning : In 1996, the European Union decided that all countries in Europe will implement a new standardized traffic control system for the railway. The systems that are available today will be replaced with ERTMS (European Rail Traffic Management System), which is a safer and more efficient traffic control system. LÄS MER

    Författare :Benjamin Oakes; [2013]
    Nyckelord :;

    Sammanfattning : Electrical arcing in the railway environment radiates wideband noise that can disturb nearbysensitive electronics e.g. signaling systems. High frequency disturbances follow conducting wiresand rails. LÄS MER

  5. 14. 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
