“…Dlatego też niezbędne jest zapewnienie wysokiego poziomu ich niezawodności, czyli zdolności do zachowania stanu zdatności, oraz bezpieczeństwa, rozumianego jako brak niedopuszczalnego ryzyka [4,6,7,9,18,19,20]. Dlatego też, cały czas trwają prace badawcze związane z rozwojem urządzeń srk, w tym również w zakresie wyposażania ich w funkcje diagnostyczne [8,10,11,12,13,14,16,17]. Wynika to z faktu, iż implementacja metod diagnostycznych może w znaczący sposób wpłynąć na zmniejszenie czasu odnowienia po wystąpieniu uszkodzenia, co powinno się również przyczynić się do zapewnienia przez te urządzenia i systemy odpowiedniego poziomu bezpieczeństwa.…”

Railway control devices are responsible for the safe and efficient operation of railway traffic. Despite the continuous development of these devices, like other technical solutions, they are being damaged. However, since railway control devices are safety-related, they are not only required to be reliable, but also to be free from unacceptable risks. The very large number of control devices, the variety of their types, the variety of technical solutions, as well as the specific failure rate make it very difficult to ensure the efficiency of these equipment. Therefore, their operation must be supported by technical diagnostics. Information obtained as a result of technical diagnostics about changes in the technical condition of devices is stored in specific data sets. However, in the case of individual railway lines plants of PKP PLK S.A. these are most often Excel spreadsheets of Microsoft Office. The authors of the article proposed to transfer these data to the MS SQL relational database with the use of proprietary software developed for this purpose.

In the case of complex technical systems that should deliver long life, high availability, safety and reliability, such as railway traffic control systems, the ownership costs many times exceed the costs of its acquisition. Therefore, infrastructure operators in order to make optimal economic decisions, regarding the systems purchase or and modernization, expect that system delivers will give complex information not only about the initial costs of purchasing the system, but also about the costs of its operation and liquidation. It allows to include in budget plans, growing requirements for the reliability availability of infrastructure as well as crucial issue-the traffic safety. Considering the widespread use of railway traffic control systems, which are part of the railway infrastructure, even small savings obtained for individual systems can be resulted into significant financial benefits for infrastructure owners and operators. One of the methods which helps to consider all of the above-mentioned types of costs is the Life Cycle Cost (LCC) analysis. In the case of railway traffic control systems it is a mandatory part of RAMS (Reliability, Availability, Maintainability, Safety) / LCC analysis. Its requirements are defined in the European Union directives, and the methodology is included in the CENELEC standards. The methodology of the LCC analysis, including economic aspects as well as safety and reliability requirements specific to railway traffic control systems was presented by the authors. LCC structure for three various examples of railway traffic control systems were considered. This economic analysis includes level crossing protection system, axle counting system and automatic block signalling. Based on these examples the differences in the LCC structure for individual systems were presented.

Railway traffic control devices are working on railway lines in different, often extreme exploitation conditions. The technical condition of these devices have an immense impact on the safety of passengers traveling by train and throughput of the railway line. Diagnostics of railway traffic control devices is very important. Continuously identification and observation of their damage allows for an effective removal and elimination of existing failures.
