Availability Evaluation of Overhead Contact Lines Based on a Stochastic Colored Petri Nets Model
IET Electrical Systems in Transportation, Volume 2025, Issue 1, 2025.Due to their nonbackup characteristics and constant exposure to outdoor conditions, the performance of overhead contact lines (OCLs) will gradually degrade over time and further result in equipment defects or frequent failures. These issues significantly impact system availability and incur substantial repair costs.

IET Intelligent Transport Systems, Volume 19, Issue 1, January/December 2025.In this manuscript, we proposed physics‐informed surrogate model, called FENet, for the first time to solve the interaction of pantograph‐catenary system. In recent years, much progress has been achieved in PCS modelling solutions. Existing solutions, however, suffer from two significant limitations: 1) An urgent concern arises regarding the ...

Total Cost of Ownership of Electric Vehicles: A Synthesis of Critical Factors
The Journal of Engineering, Volume 2025, Issue 1, January/December 2025.This study uses a systematic review to evaluate the total cost of ownership (TCO) as a tool for assessing electric vehicle (EV) feasibility compared to internal combustion engine vehicles. Findings highlight that while EVs have higher upfront costs, supportive policies and lower operating expenses can enhance their competitiveness.

Aerodynamic noise from a train pantograph
, 2014 Many studies have shown that when the speed of high speed trains exceeds around 300km/h, aerodynamic noise becomes the most significant noise source. The pantograph, or current collector, is mounted on the top of the train and is therefore not shielded ...
