:wub:Restore (diesel) service to Allentown and Scranton to get the larger cities of the NE and eastern mid-Atlantic back on the train system.
Common enough usage on this side of the Atlantic.(who calls a set of trains a "fleet"?).
Sounds right on this side of it, also.Common enough usage on this side of the Atlantic.(who calls a set of trains a "fleet"?).
Aloha(who calls a set of trains a "fleet"?)
Funny, I heard about the Santa Fe's "fleet" of streamliners as a kid, also the "fleet" of trains operated by the Pennsy between New York and Washington. I had alwasy considered "rolling stock" more of a European thing, with "cars" bot freight and passenger being more American. (Engines were a separate category altogether.)Silly me, I thought a "fleet" was made of up things that float. I'm a traditionalist, I'll stick with "rolling stock." But I imagine that means less to the general public.
But what if train 86 was running 122 mph. and then increases to 126 before braking for for a turn? What then? (Sorry.. i know that is smart-a of me but I couldn't resisit)Ok, the idea of faster speeds between WAS-NRO is more then caternary. If you think about it signals are placed every mile to mile and a half, not even. If you are running 150MPH and signals are placed that far apart and the frequency of the trains. The speed would be hard to maintain. Let's say Train 86 is on track 2 or 3 (the inside track) and 2158 is right behind it. 86 would be a mile ahead and is going 125MPH. 2158 would be going 150MPH on the same track and then all of a sudden it hits an approach medium. You would going from 150 to 45 or so and need to do that in less then a mile. That's 105MPH drop. You would do that constantly if they don't switch 86 over. Between NHV and BOS signals are placed every two miles or so and the trains are less frequent. So keep in mind it is a combination of things not just the caternary.

Also if one were to assume that the signaling system is something like what is installed in the NEC then first the Acela would hit cab 80 or something like that four blocks back. It would be very unlikely to hit a approach medium straight from 150mph anyway. That is not how 9 aspect cab signals on the NEC work.But what if train 86 was running 122 mph. and then increases to 126 before braking for for a turn? What then? (Sorry.. i know that is smart-a of me but I couldn't resisit)
Seriously though... I'm not sure I follow your logic. If the track and catenary are good for 150, Amtrak can change schedules to make it work.
You never heard of the New York Central's post-war "Great Steel Fleet"?Silly me, I thought a "fleet" was made of up things that float. I'm a traditionalist, I'll stick with "rolling stock." But I imagine that means less to the general public.
"Amtrak currently operates nearly half of its more than 300 daily trains at speeds of 100 mph or higher on their routes."Amtrak's Press release http://www.amtrak.com/servlet/BlobServer?b..._01-11-10__.pdf

While I agree with you to a point... you have to realize that Amtrak is counting several LD trains in this category as well.. Obviously all the Acelas, Regionals, Empire Service and Keystones fall into this category but also the Crescent, Lake Shore, Cardinal, Silver Star/Meteor, Carolinian am I forgetting any?"Amtrak currently operates nearly half of its more than 300 daily trains at speeds of 100 mph or higher on their routes."Amtrak's Press release http://www.amtrak.com/servlet/BlobServer?b..._01-11-10__.pdf
That's not very comforting to anyone who lives outside the NEC. That whole press release is just a list of one NEC project after another.
None of CHI-STL over 100 mph. In the peak (before Amtrak) Chicago to Milwaukee was over 100 mph.Plus there is the Chicago-Michigan corridor that sees 100 speeds as well. Does Chicago to St. Louis see high speeds at all? I'm thinking no, but I remember it being talked about.
You never heard of a fleet of planes?Silly me, I thought a "fleet" was made of up things that float.
Ask Captain Sullenberger!You never heard of a fleet of planes?Silly me, I thought a "fleet" was made of up things that float.
Though, I guess a plane might float better than a diesel loco.
Eh? The average age of a typical US carrier airline fleet is 10 to 15 years. And, yes, they do call them fleets. Rental car companies have fleets too. The first generation of 737s which entered service 40 years started being retired by the major US carriers 20 years ago. Most of them get passed on to charter carriers or less developed country airlines. There are few 727s left in active service for the major passenger airlines in the US.The airline industry is only now retiring the past 727s and 737s. I've been flying on those planes for half my life, which works out to 25 years plus. Amtrak's oldest coaches are around 30, I'd guess, but others would know for sure. Railcars should be even more long-lived than aircraft, since the basic designs and materials are so mature and they don't include propulsion systems.
