Abstract
Sweden is currently undergoing a transition phase to a new signalling system on its railway network. ATC-2 is the current point information system in use on the network. The system will gradually be replaced with ERTMS, which will become the standardised signalling system in the European Union (EU). During this period, the Swedish Transport Administration (Trafikverket) has been commissioned by the Swedish government to produce reports on the quality of delivery of the ERTMS system.

This thesis presents a description of the technical structure of ETCS Level 2 and ATC-2. Further research into the signalling systems is done by conducting a reliability analysis, utilising Trafikverket’s service monitoring reports as a source of data on... (More)
Sweden is currently undergoing a transition phase to a new signalling system on its railway network. ATC-2 is the current point information system in use on the network. The system will gradually be replaced with ERTMS, which will become the standardised signalling system in the European Union (EU). During this period, the Swedish Transport Administration (Trafikverket) has been commissioned by the Swedish government to produce reports on the quality of delivery of the ERTMS system.

This thesis presents a description of the technical structure of ETCS Level 2 and ATC-2. Further research into the signalling systems is done by conducting a reliability analysis, utilising Trafikverket’s service monitoring reports as a source of data on faults were reliability is affected. To further elaborate on this data, interviews with people working with ERTMS at Trafikverket, SJ and Infranord were conducted.

Finally, the results are presented from the reliability analysis where faults with technical aspects of ETCS Level 2 that could cause problems for reliability are summarised. Previous studies on ERTMS are included in the discussion to strengthen the findings from the analysis. Since reliability studies like the one done in this thesis have not been published to a greater extend in either Sweden or other European countries, the report utilises studies on ERTMS where the findings in said studies could have an effect on reliability for ERTMS.

Abstract (Swedish)
Sverige genomgår en övergångsfas mellan två olika signalsystem på järnvägen. ATC-2 är det nuvarande punktinformationssystemet som finns på den svenska järnvägen. Detta system ska stegvis ersättas med ERTMS, ett system som ska bli det standardiserade signalsystemet på EU:s järnvägar. Under denna period har Trafikverket i uppdrag av den svenska regeringen att ta fram rapporter som redovisar resultat och analyser om leveranskvalitén av ERTMS-systemet.

Denna rapport undersöker och presenterar tekniska strukturer inom ETCS Level 2 och ATC-2. Rapporten genomför därefter en tillförlitlighetsanalys där Trafikverkets rapporter om ERTMS implementeringen i Sverige används för att ta fram statistik om fel där tillförlitligheten drabbas. För att... (More)
Sverige genomgår en övergångsfas mellan två olika signalsystem på järnvägen. ATC-2 är det nuvarande punktinformationssystemet som finns på den svenska järnvägen. Detta system ska stegvis ersättas med ERTMS, ett system som ska bli det standardiserade signalsystemet på EU:s järnvägar. Under denna period har Trafikverket i uppdrag av den svenska regeringen att ta fram rapporter som redovisar resultat och analyser om leveranskvalitén av ERTMS-systemet.

Denna rapport undersöker och presenterar tekniska strukturer inom ETCS Level 2 och ATC-2. Rapporten genomför därefter en tillförlitlighetsanalys där Trafikverkets rapporter om ERTMS implementeringen i Sverige används för att ta fram statistik om fel där tillförlitligheten drabbas. För att utveckla undersökningen av denna statistiska data intervjuades personer från Trafikverket, SJ och Infranord som arbetar inom ERTMS.

Avslutningsvist presenteras resultat från tillförlitlighetsanalysen där problem med tekniska delar av ETCS Level 2 som kan påverka tillförlitligheten negativt presenteras. Här tas även tidigare studier om ERTMS med i diskussionen för att stärka de fynd som har gjorts under analysens gång. Då tillförlitlighetsstudier som denna rapport gör inte har publicerats i en större utsträckning vare sig i Sverige eller övriga europeiska länder, har andra vetenskapliga rapporter använts som har undersökt delar av ERTMS-systemet som kan komma påverka tillförlitligheten.
