How Effective Are Automatic Grounding Devices at the Floating Negative Rail System of a DC Powered Rail Transit System?
Currently most modern dc rapid transit systems around the world use running rails or a negative rail as the negative return circuit for the dc traction current. These rails are intentionally kept ungrounded from ground (earth) by using insulating material between the rail and earth to minimize dc stray current. This configuration of return current rail develops varying voltage with respect to g...
متن کاملThe IEEE 1473-L Communications Protocol: Experience In Rail Transit
Even before the IEEE’s Rail Transit Vehicle Interface Standards Committee (RTVISC) approved IEEE 1473, railcar manufacturers from Breda in Italy to Kinki-Sharyo in Japan to Bombardier in Canada had been designing the underlying LonWorks® protocol into their rail vehicles. But after its formal adoption in 1999, IEEE 1473-L based networks have begun to proliferate at transit properties in North A...
متن کاملEvaluating Rail Transit Criticism
This report evaluates criticism of rail transit systems. It examines claims that rail transit is ineffective at increasing public transit ridership and improving transportation system performance, that rail transit investments are not cost effective, and that transit is an outdated form of transportation. It finds that critics often misrepresent issues and use biased and inaccurate analysis. Th...
متن کاملEffectiveness of rapid rail transit system in Beijing
The effectiveness of rapid rail transit system is analyzed using tools of complex network for the first time. We evaluated the effectiveness of the system in Beijing quantitatively from different perspectives, including descriptive statistics analysis, bridging property, centrality property, ability of connecting different part of the system and ability of disease spreading. The results showed ...
متن کاملBus Transit Oriented Development— Strengths and Challenges Relative to Rail
While rail has been the focus of most planning for Transit Oriented Development (TOD), there has been recent interest in bus-related TOD with an emphasis on new bus rapid transit (BRT) systems in North and South America and Australia. This article takes a critical look at the strengths and challenges of bus-based transit systems compared to rail in relation to TOD. It includes a review of the l...
