Posted by nasadowsk on Sun Oct 30 20:52:56 2011, in response to Re: Usage of Arrow III, posted by Olog-hai on Sun Oct 30 18:47:38 2011. It was Gibbs and Hill's study on the subject that said to dump 3kv.The choices it looked at were: * 12.5kv 60hz. * 25kv 60hz. * Ditching electric for dual mode (600v) diesel operation. They explicitly ruled out multisystem MUs for some reason I don't get. The basic thought was since the NEC was 'going to be 25kv' that they should repower at 25kv. Moral of the story: watch out for stupid consultants. The other issue was the 3kv substations were all SHOT by the time they made a decision. They were maintenance bears, and there was serious talk about converting them to solid state, though that fell through after the decision to go AC was made. The stupid thing was every time NJT ordered MUs, GE offered them multi voltage capability, and every time NJT turned it down. They didn't even consider adding it during the rebuild. Whomever does equipment planning for NJT is a fucking idiot. (Though the LIRR's handling of the M-1s near the end was braindead also) |
