“…The most common implementation of this system is the third rail system (TRS). TRS consists of two primary components: a third rail that runs parallel to the primary rails of the track, as well as a connection/support device point on the underside of the LRV bogey [15]. In this way, a similar effect of the OCS system can be achieved, where a direct contact connection is utilised for power transfer, but with distinct advantages.…”

“…TRS, due to its location and lack of exposed components, results in a more robust power transfer system [16] and one that is resistant to electromagnetic interference [3]. TRS is often cheaper to implement than OCS, due to not requiring support frameworks and extended maintenance schedules [15,17]. Figure 2 shows a traditional implementation of TRS in the London Underground [18].…”

“…This leaves an evident lack of review into CPT for large-scale applications. However, with the increasing uptake and interest in CPT systems, few recent examples of review papers covering CPT technology exist [12][13][14][15][16][17][18]. These papers either present a review of WPT as applied to one specific application or a review of only recent developments, operational principles, and current limitations of CPT as a modality over the last five years.…”

Light rail vehicles (LRVs) are increasingly in demand to sustainably meet the transport needs of growing populations in urban centres. LRVs have commonly been powered from the grid by direct-contact overhead catenary systems (OCS); however, catenary-free direct-contact systems, such as via a “hidden rail”, are popular for new installations. Wireless power transfer (WPT) is an emerging power transfer (PT) technology for e-transport with several advantages over direct contact systems, including improved aesthetics and reduced maintenance requirements; however, they are yet to be utilised in LRV systems. This paper provides a review of existing direct-contact and wireless PT technologies for LRVs, followed by an in-depth critical assessment of inductive power transfer (IPT) and capacitive power transfer (CPT) technologies for LRVs. In particular, the feasibility and advantages of CPT for powering LRVs are presented, highlighting the efficacy of CPT with respect to power transfer capability, safety, and other factors. Finally, limitations and recommendations for future works are identified.

“…Pang Yanzhi et al used the fault tree method to analyze the feasibility of the train delay accident caused by the air brake relief relay failure on Nanning Metro Line 1 and provided relevant suggestions for driving safety [25]. Faults and their prevention have received attention from countries around the world [26,27].…”

The Fault Tree Analysis (FTA) method was used to analyze the accidents of high-speed trains with people and objects caught in fully automatic operation lines of urban rail transit. A fault tree was established to describe the top event, intermediate event, and basic event in the accident tree of high-speed trains with people and objects caught in train doors and platform doors. The minimum path set, and structural importance parameters of the accident were analyzed and calculated, and the equivalent tree of the accident tree was drawn. The four shortest path sets with shorter chains were selected for analysis, and effective measures were proposed to prevent the occurrence of high-speed train accidents involving people and objects.
