A Solution to Remove Railway Track Discontinuities at Spiral Junctions [PDF]
International Journal of Mechanical Engineering and Applications, 2020 To design railway track layouts, engineers use tangent and circle segments. To maintain curvature and bank angle continuities between flat straight lines, with zero curvature, and banked circles, they use spiral segments where curvature and bank angle vary linearly as function of distance.

Geographic characterization of railway systems [PDF]
, 2021 Railway systems provide pivotal support to modern societies, making their efficiency and robustness important to ensure. However, these systems are susceptible to disruptions and delays, leading to accumulating economic damage. The large spatial scale of delay spreading typically make it difficult to distinguish which regions will ultimately affected ...

Rail Topology Ontology: A Rail Infrastructure Base Ontology [PDF]
LNCS 12922 (2021) 597-612, 2021 Engineering projects for railway infrastructure typically involve many subsystems which need consistent views of the planned and built infrastructure and its underlying topology. Consistency is typically ensured by exchanging and verifying data between tools using XML-based data formats and UML-based object-oriented models. A tighter alignment of these

Integrating Optimal EV Charging in the Energy Management of Electric Railway Stations [PDF]
arXiv, 2023 In this paper, an electric railway Energy Management System (EMS) with integration of an Energy Storage System (ESS), Regenerative Braking Energy (RBE), and renewable generation is proposed to minimize the daily operating costs of the railway station while meeting railway and Electric Vehicle (EV) charging demand. Compared to other railway EMS methods,

Physical Attacks on the Railway System [PDF]
arXiv, 2023 Recent attacks encouraged public interest in physical security for railways. Knowing about and learning from previous attacks is necessary to secure against them. This paper presents a structured data set of physical attacks against railways. We analyze the data regarding the used means, the railway system's target component, the attacker type, and the
