Feinman on Mon Oct 20 14:52:17 2014. or is that just because of the age of the infrastructureFWIW, how often does the wire fall on light rail systems around the country or NJT's Morris & Essex Lines and the NJCL? As much as some here would argue that the PRR's system is bullet proof, it's an old system that isn't constant tension catenary. In the rest of the first world, catenary is the standard for electrification, and it's used in places where people actually rely on usable railway service. The French ripped up their mainline third rail, the British have banned any new third rail electrifications unless it's an extension of an existing line, and the third rail S-Bahns of Germany, Berlin and Hamburg, are considering new extensions that use rolling stock that will use existing overhead catenary. With the exception of subway systems*, third rail is a dead end for mainline electrification, and nobody wants to keep building a substation every mile or so when you have nearly thirty to fifty miles to electrify. *And FWIW, you have Asian systems like Tokyo and Shanghai which have lines that use catenary... |
