“…Recent advanced sensing technologies and the development of the Internet of Things make remote, labour-free, continuous, and detailed monitoring increasingly cost-efficient, and maintenance records can be stored electronically and accurately for failure investigation and risk analyses [12,13]. In recent years, published solutions have included fitting sensors to railway overhead line equipment and remotely monitoring overhead line leaning stanchions [14], tension [15,16], temperature [17], vibration [18], and neutral sections [19]. Because of the droppers' and jumpers' small size, substantial quantity, and wide distribution, infrastructure-borne monitoring solutions are likely to incur extremely high capital expenditures and operating expenses.…”

Droppers and jumpers are important components of railway overhead line electrification. Their effective maintenance is critical for the railway’s safe and reliable operation; the consequences of their failure can be disproportionally serious. This paper systematically analyses the components’ failure by applying the method of failure modes and effects analysis to the maintenance records and incident statistics of Britain’s East Coast Main Line. The analysis is presented with photographic evidence and a review of the current maintenance strategy and practice that addresses the risk of failure. These results can support improved dropper and jumper design and the development of more effective maintenance strategies to further prevent failure and operational disruption.

“…For the OCL monitoring, this type of sensor was mainly used for contact force and pan-head acceleration measurement (Boffi et al, 2009;Wagner et al, 2014). Another application is their use for hotspots detection on OCL (Theune et al, 2010) as well as the steady arm uplift (Laffont et al, 2009). These sensors have numerous advantages for contact force measurement regarding their size and weight and electromagnetic compatibility.…”

The railway industry in European countries is standing a significant competition from other modes of transportation, particularly in the field of freight transport. In this competitive context, railway stakeholders need to modernize their products and develop innovative solutions to manage their asset and reduce operational expenditures. As a result, activities such as condition-based and predictive maintenance became a major concern. Under those circumstances, there is a pressing need to implement prognostics and health management (PHM) solutions such as remote monitoring, fault diagnostics techniques, and prognostics technologies. Many studies in the PHM area for railway applications are focused on infrastructure systems such as railway track or turnouts. However, one of the key systems to ensure an efficient operability of the infrastructure is the overhead contact line (OCL). A defect or a failure of an OCL component may cause considerable delays, lead to important financial losses, or affect passengers safety. In addition maintaining this kind of geographically distributed systemsis costly and difficult to forecast. This article reviews the state of practice and the state of the art of PHM for overhead contact line system. Key sensors, monitoring parameters, state detection algorithms, diagnostics approaches and prognostics models are reviewed. Also, research challenges and technical needs are highlighted

This article presents the results of studies on the impact of the percentage of copper in the carbon composite of the railway pantograph contact strips on the maximum temperatures of the contact wire of the overhead contact line. The tests were carried out in accordance with the requirements of standards [7, 9] and TSI [4]. The obtained relationship allows for an initial assessment of the introduced materials due to the contact wire heating criterion based on the copper content of the carbon composite, which greatly facilitates the design process and the initial assessment of the pantograph slides performance. This publication also indicates the minimum value of the percentage of copper at which the standard requirements [7] for railroad wire heating are still met.
