Posted by trainsarefun on Thu Feb 28 20:26:47 2008, in response to Re: LIRR DE/DMS Some reasons why, posted by Chris R16/R2730 on Thu Feb 28 13:27:40 2008. It's an interesting back and forth between WillD and you. Some observations:1. As I've said before, without LIRR setting priorities and MTA budgeting on the issue of electrification and better service, there's a ton of missing data. 2. You have a valid point that rolling stock purchases for straight DC equipment would be cheaper. It also has historical precedent on LIRR, although that same precedent indicates that the pace of electrification is very slow. 3. WillD has a valid point that AC electrification is cheaper and it requires (many) less substations. Historically, the New Haven Line electrification counts as a huge success, I think (and not only that - consider furthermore how much AC catenary the NYNH&H tore down as well, e.g., on the Bay Ridge Branch of LIRR and over the Hell Gate. 4. Up to this point, I would give the edge to WillD, but there's a big BUT to follow, since I think he has two big, and so far fatal, flaws to his proposal: 4a. How would a locomotive on the third rail pulling DC operate at speed successfully? 4b. A political problem: People - NIMBY people especially - tend not to like overhead wire; can opposition be overcome? I'm not so sure, to be honest. |
