Posted by Joe V on Sun Feb 15 07:53:58 2015, in response to Re: How 3rd Rail Running Commuter Rail Could Have Avoided / Ameliorated Fiery Crash, posted by Fisk Ave Jim on Sat Feb 14 20:51:20 2015. Further disadvantages of Dual-modes:1) None are available. Super Steel is dead. Genesis are no longer produced, whereas 3rd rail MU's are easily available 2) Small order would make them very expensive 3) 3rd rail gapping issues. Maybe not a big deal in GCT, but would be on the LIRR. 4) Train performance declines with train length, which is a rather rinky-dinky 7 cars on MN 5) The MDBF of the P32 is not disasterous, but not wonderful either, and far worse than the 30 year old M3's. M7's are 300,000 miles. Your Poughkeepsie trains are limited to 7 cars. Top and tail to lengthen is expensive. So they resort to adding frequencies and adding MU's out of Harmon to take up electric zone stops where needed. That all adds to operating costs. Unlike all other diesel lines on MN and LIRR, Poughkeepsie ridership quadrupled because it started form virtually NOTHING - 2 car RDC's shuttles every 2 hours that could barely make the trip. The Danbury line gets the same 3 thru trains it had 40 years ago. People also drive to the Upper Harlem Line to catch the MU's. |
