Analysis of Rail Potential and Stray Current for Taipei Metro
IEEE Transactions on Vehicular Technology, 2006Taipei Metro adopted the diode-grounded scheme for stray current collection in construction of its cross rail network. During operation of the network, a high rail-to-earth potential (V/sub rail/) has been observed at the east end of the Blue Line (i.e., stations BL13-BL16).

Potential Effects of Mercury on Threatened California Black Rails
Archives of Environmental Contamination and Toxicology, 2008San Francisco Bay (SFB) estuary sediments contain high levels of mercury (Hg), and tidal marsh resident species may be vulnerable to Hg contamination. We examined Hg concentrations in California black rails, a threatened waterbird species that inhabits SFB tidal salt marshes.

Guided wave inspection potential of defects in rail
NDT & E International, 2004Abstract The authors provide the results of experiments they have conducted on rail at test tracks and on an operating railroad. Results are presented that suggest that the frequency range [40,80] kHz readily supports guided waves. Theoretical results including roots of the dispersion relations for rail and a sample of wave displacement ...

The Potential of Ultrasonic Surface Waves for Rail Inspection
AIP Conference Proceedings, 2005Rail inspection using ultrasonic surface waves could provide a more reliable and efficient alternative to conventional ultrasound for the detection of surface cracks. This paper examines the basic properties of such surface waves at frequencies around 250 kHz.

IECON 2019 - 45th Annual Conference of the IEEE Industrial Electronics Society, 2019
At present, abnormal rise of rail potential in DC traction power supply system of urban rail transit has become a difficult problem in line safety. The mechanism and distribution of abnormal rail potential need to be clarified. In the traditional analysis method, the mode that single train operating in single power supply section is far from the mode ...

The potential of rail as an environmental solution: Setting the agenda
Transportation Research Part A: Policy and Practice, 1994Rail is often advanced as an environmentally superior alternative to road transportation. A market segmentation analysis shows rail has a relative advantage in regular long distance trips to high density nodes. Yet, such trips are a limited and shrinking share of the total transport market.

Evaluating the potential benefits of a rail traffic movement planning algorithm
Proceedings of the 31st conference on Winter simulation Simulation---a bridge to the future - WSC '99, 1999Railroads have large investments in capital items such as track, trains and terminals. Optimizing the use of their resources has the potential of enormous payback. Precision Train Control/sup TM/ (PTC) is an effort to optimize the flow of trains on the railroad line in order to increase the return on capital.

Single train movement modelling and simulation with rail potential consideration
2016 IEEE/SICE International Symposium on System Integration (SII), 2016In general, the study of the train movement simulation begins with learning a simple single-train movement modelling. To be more realistic and more complete, the model should be able to calculate the profile of rail potential while a train is moving since rail potential plays an important role in the design of electrified railway service and is not ...

Research on Technical Measure for Rail Potential Reduction
Applied Mechanics and Materials, 2012The super-high potentials of Metro rail will have a crucial influence on Metro’s safe operation, personal safety and the corrosion of underground metal structures. This paper analyzes the principle of the generation for rail potentials and the influencing factors of the high and low Metro potentials.
