I know this might be a dumb question or i don't know what is but here i go.

I have Traveled alot on Railways and Airplanes, I have been on the Acela Express (Washington DC to New York Penn), and another time from Philadelphia to Washington DC in 2013, also this happened when i traveled on the Pacific Surfliner in 2014, i live in Florida and here we don't have High Speed Rail although we are sort of getting one in a year or two?

Every time the Trains go at the highest speeds they are allowed to go i always hear a wind sound when i press my ear to the window, it sounds incredible and it amazes me of how we humans are capable of building such Transport as it is, it sounds like if i was on a jet aircraft in a way.

I don't know if i am saying right or maybe i am misinterpreting it please can someone tell me what it is?

Weight and maintenance.

HSR has a tight requirement of 18t axle load and a (relatively) high wear due to the speeds achieved, so the bogies and trains have to be the lighest as feasible.

Also, with the large curve radius used on high speed routes, its a lot of unnecessary complexity.

All Aboard Florida will open in late 2016 from Miami to West Palm Beach & in 2017 from West Palm Beach to Orlando...future expansions have it going all the way up to Jacksonville...

You are not imagining things. What you are hearing is aerodynamic noise, along with other noises such as those emanating from the wheel-rail interface and pantograph-catenary wire interface. At high speeds these manifest themselves in that airplane-like noise. At very high speeds (higher than any current US service speeds) there is a turbulent boundary layer that is generated along the surface of a trainset, like an aircraft fuselage. This generates even more noise.

Well of course there will be enough demand at the weekend. The more important question are workdays though. Las Vegas still has a decent amount of people in town during the week, but is it enough for a HSR service? For me personally a Los Angeles - Phoenix service would make much more sense if you wish to expand eastwards.

The cause was material failure because of a wheel construction that should never have been used on a high speed train. After the wheel failed the train continued for several kilometers before derailing at the first switch it encountered, which unfortunately was located just in front of a viaduct of which the supports were knocked down by the derailed train, causing it to collapse onto the derailed train.

Because of this accident tests were done and train constructions were changed, so that 'regular' trains are now nearly as safe as jacobs-bogie articulated trains.

Thank you KK Jetcar for the explanation i always find that sound when the Train is going high speed very awesome because its like when a jet aircraft takes off to the skies.

Also I heard that the US government is looking into expanding high speed rail tot he southeast of the USA to Richmond, Charlotte and such?

Amtrak refutes US senator’s assertion on HS train deal



SOURCES at Amtrak have told IRJ's North American sister publication Railway Age, that claims by the US senator for New York, Senator Charles Schumer, that Amtrak has selected Alstom as preferred bidder for a contract to supply a fleet of high-speed trains, are premature.

Amtrak says that while Alstom is a bidder for the contract, the procurement process is still open and that two pre-qualified suppliers are still in the running for the contract.

Senator Schumer claimed during a visit to Alstom's Hornell plant in New York state on September 21 that the Amtrak board was about to select Alstom as the sole bidder to negotiate the contact. Amtrak sources say Schumer took liberties to declare a winner prematurely when Amtrak is still negotiating with two suppliers.

The new trains are needed to replace Amtrak's Acela fleet as part of a $US 2.5bn project to upgrade the Northeast Corridor linking Boston, New York and Washington DC.

The eschede accident it was caused for a defficient boggie (wheels)

So I guess this option is considered carefully each time they choose a train. Maybe newer tilting systems would become more popular.
I couldn't find a single such pic, I looked for tilting train failure. And motion sickness is a thing of the past now.

Pretty sure Amtrak would love to get rid of those ridiculous FRA regulations forcing them to put tanks on their lines completely ruining the tracks.

There really isn't much mixed, passenger/freight, traffic on the NEC, though...

As its first meeting nears, high-speed rail panel already behind schedule



Quote:
As the Nevada High-Speed Rail Authority prepares for its inaugural meeting Tuesday, the five-member board already is hopelessly behind in meeting a deadline established by the enabling legislation.

Board members meet for the first time at the Regional Transportation Commission of Southern Nevada headquarters at 5 p.m.

The board was established in May when Gov. Brian Sandoval signed Senate Bill 457 into law. The board's purpose is to oversee the development of what is being called the Nevada High-Speed Rail System, a train that would connect Southern Nevada with Southern California.

Initial board appointees are George Smith, executive vice president of Bank of America Merrill Lynch; Tina Quigley, general manager of the Regional Transportation Commission; Hualiang "Harry" Teng, director of the railroad, high-speed rail and transit initiative and an associate professor of UNLV's Department of Civil and Environmental Engineering; Fred Dilger, principal and transportation analyst at Black Mountain Research in Henderson; and Peter Thomas, managing partner of the Thomas & Mack Co. in Las Vegas.

Organizational topics dominate the first agenda, which also includes an explanation of the procedure for selecting a franchisee to build and maintain the railroad.

LA Bullet Train Wants to Test-Drill for a Tunnel Under the San Gabriel Mountains

Quote:
The California bullet train will be a $68-billion wonder of the world once it figures out the small problem of how exactly to get the trains out of Los Angeles. The High Speed Rail Authority has had trouble finding a route from Burbank to Palmdale that doesn't ruffle feathers. In response to the intense public outcry over the 14 Freeway route, the Rail Authority announced last year it was looking into a possible tunnel option to cut through the San Gabriel Mountains, too, and they've since identified three potential routes for that tunnel. Now, the rail authority has asked the U.S. Forest Service for permission to conduct a few drilling tests in the northwest part of the Angeles National Forest to determine which of the tunnel routes are most feasible, reports the San Gabriel Valley Times.

Any idea how long would such a tunnel be? Seems to make a lot of sense to go for the tunnel there. In addition to shorter route and less impact on nature it would reduce the amount of land that needs to be bought.
