Posted by trainsarefun on Tue Aug 12 00:26:47 2008, in response to Re: LIRR/NYCR MP54's, posted by Olog-hai on Tue Aug 12 00:06:18 2008. Don't quote me on this as the authority, but from what I understand, MNR uses a different cab signal system - or something to that effect - such that it functions passably for the commuter trains that MNR is running on the New Haven Line, but it's pokey by intercity standards; basically there isn't as much distinction at the higher speeds. I'd defer to anyone who knows more about the exact issue involved, but a sticking point seems to be that someone else other than CT DOT and MNR should foot a good chunk of the money to bring the speediest portions of the road up to full capability, since MNR isn't in the habit running trains over 90 mph on most trips. Most of the New Haven Line straightaways are what, maybe MAS of 70-80 mph?Also, not all of MNR territory is under auto control, either - Danbury Branch is the first exception that comes to mind; Waterbury Branch too. The other thing that takes away speed on the New Haven Line is the proscription on tilting, the many curves, and the low speeds 30-40 mph mostly over bridges of which there are many. |
