I was riding on Metro-North between New Haven and NY just the other day, and I have a couple comments (and questions) to ask...
For one, the track was a bit curvy. We were held to 60 MPH most of the way, and even the Acela couldn't do much better than 90 if it was allowed.
Also, the MU's seemed to be riding a bit rough. I saw several high-speed crossovers (without frogs; there's a second set of points in place of the frog) but there were a lot of standard switches all over the place which didn't help to make the ride glassy-smooth. And the MU sets (the older M3s, I think; no M7s here!) were showing their age and use.
Here's my question about that. Are the MU sets well maintained with good springs, and does the Acela ride better? If the MUs have old springs, their riding characteristics can be explained. They are run hard at high speeds, many hours a day, and could definetely be a bit worn. The Acela probably runs a lot smoother.
While the Acela is definetely held back to some degree, I don't think that line could be increased to anything above 125...
I have been trying to get the speed performance specification figures for the New Rochelle - New Haven upgrade of MN"s/CONN DOT's CAT that is now being replaced. Anyone know how much is completed? Once that upgrade is finished there MAY be an increase in speed on that segment. It is my understanding that the old NH CAT is the limiting speed especially on very hot or very cold days. If the performance of the new CAT is better then maybe a few minutes can be shaved south west of New Haven.
Actually isn't it probably the best that turbos were not used for the Acelas as the enviromental and oil conservation people would now be yelling for its replacement with electric traction.?
Also no upgrades of CAT yet south of NYP just necessary repair. Until the electrical distribution problems are solved south of NYP the AMTRAK total load on the PRR 11Kv 25 HZ system cannot be increased. Now the stimulus bill is probably going to solve those problems by Mar 30, 2011.
The stimulus bill does not talk at all about upgrading any catenary for higher speeds.
Still, that's a lot of money for a measly 15 mph speed boost in three or four tiny sections, don't you think?
As for loading guage concerns with respect to tilting of Acela, that was an urban myth pushed by the anti-Amtrak political community.
Unfortunately the Metro-North stupidity is real.
The Catenary issue strikes me as a major impediment to increasing speeds on the NEC..After all the new catenary from New Haven North is designed specifically for HSR with the pulley/ballast system to maintain tension in varied wind conditions.South of NH the older NY,NH& H and PRR catenary is not built to anything like those specs, replacing it would be quite expensive. I have not looked into what the Stimulus Bill will do for the NEC, does anyone know if Amtrak is planning an upgrade?

blue streak 1 Boston:: Lets see almost all the money for the electrification came from the Congressional AMTRAK dedicated funds. Beside the obvious items of CAT; new signaling (acses), track upgrades (anyone know the PC times that we can compare NH - BOS NE regional is now about 2:30?). The new Haven - NYP is limited because of the MN problems ( a whole another set of items) There are the 20 - 30 some roads that went over that segment that had to be raised or eliminated; The grade crossings that were either eliminated by over/underpasses or completely closed; bridge upgrades to eliminate open deck spans; South station necessary improvements; Providence station moved; new South station maintenance facility; etc. Now the draw spans that are at the end of their useful life. The point is that on any route first you fix a route closing item then you get rid of the slowest segments first (less deceleration and acceleration time). That is the way you speed up any route. Now once those route closing problems (example: the Conn river draw) are in a state of good repair then finally maybe some route straightenings and permanent slows can be addressed. There ar presently 156 route miles from New Haven - BOS.Acela schedules about 2:10. it will be impossible to cut that time to under 1:30. If the old NH route central Conn were reinstated maybe with no stops 1:20 time. Incrementally if one new realignment / speed up projec was started every other year covering about 15 miles ($100M +) then there would be a slow reduction in transit times in 20 yrs. The NC DOT model of incremental tiime reduction seems to placate the public. As far as longer times for Acela you have a much more satisfied public when your on time is above 90%. One late train kills a lot of good will (look at what happens to the non commuter trains when their on time dips to 50% or less.

In 1955 The Senator was carded for 2 hours and 43 minutes from Boston to New Haven, with 4 hours and 20 minutes from Boston to New York. Of course, in 1955 the train would have been in the hands of the New Haven from Boston to New York.
Jerry Pier When the big push was on to electrify New Haven to Boston, a series of test runs were made by the FRA and CONEG (Coalalition of Northeastern Governors) with various non-electric trains, some with tilt and some without. These tests and simulations by FRA and independent contractors showed that the many curves (equivalent to 10 full circles) would define the schedule. This work also showed that a gas turbine powered train similar to the RTLIII's presently parked in Bear, DE, would match an electrified train within one or two minutes. Electrification had more Congressional and emotional support and this triumphed over good engineering sense. Jerry Pier

For this I blame the advocacy community as much as the gub'mint, and this is some of the reason I respond in rebuttal to some of the more glib pronouncements on these pages.
When TurboTrain designer Alan Cripe died in the late 1990's, NARP noted his passing in their newsletter with a remark to the effect that he had been an obstacle to the electrification north of New Haven on account of his continued promotion of turbine trains. NARP could have honored him on hearing of his death by reminding people about his role in the United Aircraft TurboTrain and its part in the Northeast Corridor Demonstration project that set the stage in its own way for Amtrak and the continuation of passenger service to this date, but they chose to be snarky about this opposition to a pet project supported by NARP.
With respect to the testing of tilt trains, what was the verdict on that highly-curved route with respect to conventional vs passive tilt such as TurboTrain and Talgo vs active tilt such as LRC, Pendolino, and the like? The Acela is supposed to tilt, and my understanding is that it does tilt, but owing to clearance reasons it is limited to the amount of tilt of the passive systems such as Talgo. Do they tilt the Acela, and does it help their schedule any, and it would their schedule be better if they had worked out the loading gauge so they could do full tilt?
If GM "killed the electric car", what am I doing standing next to an EV-1, a half a block from the WSOR tracks?
BostonTrainGuy Ten years ago (May 1999 issue), Trains had an extensive article on the upcoming new Acela train (“Amtrak’s Extreme Machine”). The article mentions the extra width of the cars to offer wider seats and aisles which will limit speed on certain curves. It mentions the 90 MPH speed restriction on Metro North. It talks about the planned signal system and the new electrification. It mentions many plusses and minuses but said nothing is going to prohibit the three-hour performance requirement for the Boston – New York segment. However, when the train finally did start to run in the fall of 2000 the Acela took 3 hours and 28 minutes to cover the 231 miles. Since then there have been millions of dollars spent and many improvement projects completed (not sure of the timeline but examples are: new high-speed crossovers, Thames River Bridge replacement, Stamford Station redesign with high speed passing track, New Rochelle redesign, third freight track in Rhode Island, fourth track added in Attleboro, new crossties, etc., etc., etc.). So lots of money spent and lots of big improvements. Now nine years and millions of dollars later these improvements have resulted in an Acela schedule which is actually L-O-N-G-E-R! What is wrong with this picture? A three hour schedule would require an average speed of only 77 MPH! Amtrak has made many incremental infrastructure improvements, but none of them has resulted in any incremental performance improvement. Why is it that the Acela hasn’t benefited from any of these expensive projects? Is Amtrak really capable of providing high-speed rail or is it time to find another solution?

Not lots of money by rail standards.
The thrid track in Rhode Island was so the P&W could run daylight freight service to Quanset Point Industrial Park without getting in the way of Passenger service. The bridge at New London was old and tired, it still leads to a reverse curve at the ferry dock and raillroad station with very low approch speeds. From Westerly Rohde Island through New London is the series of Grade Crossings that require speed restrictions (and yet an Acela still hit a car killing 3 people). The New Rochelle changes did help a lot.
Where the money is needed would be to raise the speed restriction south of New York. The replacement of the 70 year old PRR Catenary and the replacement of defective ties throughout the Corridor. Route 128 Station to the Rhode Island line (Boston Switch) and Warwick to Westerly RI is still the only area of full speed (150 mph).
The 20 Acela train sets have made people, here in the northeast, turn back to rail for ontime, nearly delay proof, travel.

Ok. What are we going to do? Ideally a true high speed railroad would need seperated, dedicated right of way. Between Boston and D.C., where are we to find new property for such a plant? Or where do we put the commuter and local congestion? While it is easy to blame private freight railroads for not carrying the ball (passenger trains) it cannot be overlooked that they need plant for thier product which likewise cannot be choked with passenger trains. Where do you put a new, high speed right of way?
Also, I fear there are other factors than economics and congestion here. I also fear there are lawyers/insureres purveying fear to our politicians and business leaders that should such high speed rail develop the liabilities would be great. Again we must ask how does it get done elsewhere?
So: land and liability are really our stumbling blocks. What do we do?
RIDEWITHMEHENRY is the name for our almost monthly day of riding trains and transit in either the NYCity or Philadelphia areas including all commuter lines, Amtrak, subways, light rail and trolleys, bus and ferries when warranted. No fees, just let us know you want to join the ride and pay your fares. Ask to be on our email list or find us on FB as RIDEWITHMEHENRY (all caps) to get descriptions of each outing.
Boston's original question is a great one! We keep dumping (who knows how) many hundred millions into "improving" the NEC but it is not reflected in the schedules. The Acelas are stuck with a run time of just short of 3:40 on the New York/Boston run, which is an average speed of about 65 mph.
There has to be a lesson here that is applicable to the Administration's effort to create several "high.speed" corridors.
Maybe if the proposed possible extension of electrification of the NEC to Richmond happens we may see Acela service all the way to Richmond. --- But don't hold your breath.
We had a similar problem here in California with the HSR program here. Almost until the very end of the decision making process. Mag-Lev with speeds of 350 mph was in the running until Caltrain and several of the communities along San Francisco Bay voted it down in favor of the conventional rail 220 mph system. Cost was twelve billion difference.

"Is Amtrak really capable of providing high-speed rail or is it time to find another solution?"
What's the other solution?
The best solution would be to foster a competitive market environment where only the best service providers would survive. Unfortunately, given the dismal economics of passenger rail, no investors will put their money or the money of their stockholders into passenger rail. So a competitive solution is probably not in the cards.
As long as there is only one service provider, i.e. Amtrak for most intercity trains and state or local agencies for commuter rail, the service provider has no strong incentives to do things better, faster, cheaper, which is the key for better service.
One way to improve the situation would be to have the tracks in the U.S. owned by one organization, preferably a private operator, and open them up to anyone who wants to run a train on them and can meet the operating standards. Unfortunately, the government does not have the money to motive anyone to buy the rights-of-way; the government would have to at least subsidize the transition, and the freight railroads would never allow it to happen.
So we are stuck with Amtrak, at least for now, and there is little in the way of constructive alternatives on the horizon.
But Boston, in America passenger train progress is measured by whether or not a train runs. Then you count the years from its beginning to measure the finer points of progress. If the public uses the train and the politicians and big business operators don't scuttle it, then that's progress!
