The article presents a discussion leading to the identification the possible causes of disturbances in train movements under the supervision of the European Rail Traffic Management System ERTMS. As a consequence of detected events, unintentional initiation of a train braking procedure occurs despite the absence of objective reasons for such behaviour. In essence, the paper presents the ERTMS as a real-time system based on the two subsystems ETCS and GSM-R. Each of these subsystems includes a vehicle part and an infrastructure part. The article starts by identifying general considerations that may affect the lack of compatibility between vehicle and trackside infrastructure as a result of changes in versions of the specification (baseline). The following part of the article reviews the process leading to train braking is reviewed. The next part of the article refers to ETCS scenarios and parameters affecting the system response during operation. It referred to the considerations of message transmission between the ETCS ground infrastructure and the vehicle via the telecommunications network, including the GSM-R. The final section focuses on the causes and consequence of the overlap of the RBC’s and GSM-R radio cells boundaries. The article concludes with a brief summary and conclusions.

W artykule podjęto dyskusję prowadzącą do wskazania możliwych przyczyn zaburzeń w ruchu pociągów pod nadzorem europejskiego systemu sterowania ruchem kolejowym ERTMS. W następstwie wykrytych zdarzeń dochodzi do nieintencjonalnego wdrażania procedury hamowania pociągu pomimo braku obiektywnych przesłanek do takiego zachowania. Zasadniczo, w artykule przedstawiono system ERTMS jako system czasu rzeczywistego oparty na dwóch podsystemach ETCS i GSM-R. Każdy z tych podsystemów posiada część pojazdową i infrastrukturalną. Na wstępie artykułu wskazano na ogólne przesłanki mogące mieć wpływ na brak zachowania kompatybilności pojazdu i infrastruktury torowej wynikającą ze zmian w kolejnych wersjach specyfikacji (baseline). W dalszej części artykułu przeprowadzono proces prowadzący do hamowania pociągu. W dalszej części artykułu odwołano się do scenariuszy ETCS i parametrów mających wpływ na reakcje systemu w czasie działania. Odniesiono się do uwarunkowań transmisji wiadomości pomiędzy naziemną infrastrukturą ETCS i pojazdem poprzez sieć telekomunikacyjną, w tym GSM-R. W końcowej części skupiono się na przyczynach i następstwie wdrażania hamowania pociągu będących konsekwencją nakładania się granic obszarów sterowania ruchem kolejowym objętych obszarami odpowiedzialności RBC i obszarami komórek sieci radiowej GSM-R. Artykuł kończy krótkie podsumowanie i wnioski.
