“…The method involves quantitative and qualitative evaluation of failure effects using computer aided technology to identify potential failure bottleneck problems and suggest corresponding modified measures. [33] Reliability Analysis of Metro Vehicles Operating in Poland [34] Reliability and Availability Assessment of Railway Locomotive Bogies Under Correlated Failures [3] The paper proposes a framework called Fault Maintenance Trees (FMTs) that integrates fault tree analysis with maintenance to investigate the effect of different maintenance policies on the reliability and availability of a system. The framework supports a wide range of maintenance procedures and dependability measures, including the system reliability, availability, mean time to failure, as well as the maintenance and failure costs over time, split into different cost components.…”

“…As presented in [10] these include, for example, ETA (Event Tree Analysis); FTA (Fault Tree Analysis); FMECA (Failure Mode Effect & Criticality Analysis). These and others methods are among others used to conduct process of identification of the weakest components of rail vehicle [39] (including metro vehicles [30]), evaluate different components of rail vehicles such as bogies [26,29], running gear [34], heating, ventilation and air conditioning system (HVAC) [2], doors [3,13] and others. It is worth noting that the list of methods by which the risk may be assessed is not finite, it is the railway entity that conducts it that makes the choice.…”

Maintenance management systems have been operating in the European railway market for many years. However, implementation of the new legal regulations means that the impact of the structured system approach is constantly developing. This new approach focuses on management of the safety critical components (SCC), where the main involved parties are rolling stock manufacturers and the certified entities in charge of maintenance (ECM). The aim of this article is to present how changes to legislation affect development of the maintenance systems, both in the context of their requirements and criteria used, as well as in relation to a requirement of rolling the certification process out to all ECMs, irrespectively of the types of vehicles are used by them. Furthermore, the article focuses on critical safety components and respectively challenges faced by entities on the railway market.Therefore, the process of identifying SCC is described and analysed by providing examples of components that most frequently appear on the list of safety critical components which were developed in the Polish railway market.

Improving the energy efficiency of a tram’s running gear

et al. 2023

This research analyses the influence of some design features of an undercarriage of a tram on the energy efficiency in terms of mechanical energy losses during its operation. The work includes the comparison of results of the research from two main points of view, namely from a running gear design and a railway wheel design. Two variants of a tram’s bogie are investigated. A standard bogie and a bogie with a system that allows a radial adjustment of the wheelsets in curves. Two designs of a railway wheel are compared, a wheel with the traditional construction scheme and a wheel with a perspective construction scheme. The values of mechanical energy losses due to slippage in the contact between the wheels and rails are analysed. These losses are obtained with reference to a specific route and the value of the average power dissipated. Moreover, an analysis of advantages and disadvantages of bogie designs has made it possible to consider the most appropriate bogie design in terms of ensuring the energy efficiency. In this case, the bogie design with the wheels with the perspective construction scheme can be considered as the optimal option.
