There are no such "limits"- FRA has not even drawn up guidelines for HSR lines running at speeds greater than 150mph.
It is understood that 360 ton compressive load requirement doesn't work based on Acela experience of too much wear and tear.

The next step is to downgrade it to UIC requirement of 200 ton compressive load. FRA already approved UIC train service on Caltrain, so extending it to high speed train is no brainer, and non-Japanese/Chinese vendors already meet UIC requirement.

Shinkansen is of standard gauge, same as all other high speed railways.

However, Shinkansen body profile at 3.4 meter is 300 mm wider than the US limit, thus Shinkansen trains cannot run on existing tracks even if there is no mixed traffic issues. Because of this issue Japanese are offering E6 for California, a narrower 2.9 meter mini-Shinkansen type model. However, this one is still not UIC crash standard compliant.

Very interesting, if it is just a difference of body width, it ought to be easy to modify the design for CA's needs.

Japanese are already addressing this issue with their 2.9 m wide E6.

Chinese on the other hand have nothing in their product line up that could meet the US railway body dimensional requirement, because Chinese adopted Japanese Shinkansen profile.

Another factor with the CRH380A is that the manufacturer may not consider it a viable use of their resources modifying the design for the US market. HSR in China is a much bigger market, and the Chinese government is keen to hand as much of the work as possible to domestic manufacturers. As US regulations are very different to those in Europe and Asia, it may simply not be worth the time and effort to customise the product for one relatively small, and far from certain market.

Not at all, since the Chinese government would consider it a great national propaganda worthy material to be able to sell something of this grand scale to the US market and they would sweeten their proposal with the fattest financial aid package to land the deal.

It's the issue of the Chinese being unable to meet the US technical and safety regulations that's blocking the Chinese bid, not the lack of desire on the Chinese part.

Shinkansen are quite wide but not excessively so compared to other HS networks. I would be shocked if the US HS loading guage wasn't as big as european or asian HS guage (which are pretty much the same), given that most US railroads are already of a larger loading guage, and in fact the US has the biggest in the world, some routes cleared for 6 metres in height.

Building a slightly smaller (or bigger) cabin is not going to be an issue for any manufacturer. Same bogies, same wheels, same suspension, same equipment, same almost everything thats expensive.

Most UIC high speed trains are 2.9 m wide, opposed to Shinkansen's 3.4 m.

http://en.wikipedia.org/wiki/Loading_gauge

UIC : 3.15 m(2.9 m for high speed trains)
USA : 3.2 m
Shinkansen(Japan and China) : 3.4 m

Shinkansens and CRH380 were not designed with crashworthiness in mind. Cabin reduction will not address this problem.

At least Kawasaki is aware of this problem and is busy developing efSET, a model that follows UIC standard and not Shinkansen standard, but no one knows when efSET will be ready for commercial service.

Regulations.... the things that will make American HSR a fantasy for years to come.
EDIT: WHAT... THE... HECK... is this California bill? Is this some kind of joke?!? This cannot be real?!!

There is a "sort-of-US-national-bullet-train-model" under development at Space Coast, the organization that used to work on canceled Constellation moon rocket project.

The base model for the project is said to be KTX(Not clear if this is KTX-II or the upcoming HEMU-400X), and constellation engineers are being retrained on high speed rail, train, and signaling technology by KTX engineers.

South Korea opened its state-owned high-speed rail program in 2004. Based on the French high-speed rail system, the Korea Train eXpress (KTX) can travel 217 mph and incorporates an electrified, overhead rail that allows it to connect to the French line.
I have no idea what they are implying here. Firstly the KTX only does 186mph, secondly how does the 'overhead rail' allow it to connect to the French line? France is several countries away from S.Korea, although I would like to see the day I could go between them by HSR.

The First High Speed Rail Station Breaks Ground

In San Francisco today, a group of top local and national political leaders gathered to break ground on the new Transbay Terminal – the first high speed rail station in California, and potentially the country (depending on whether you define the Acela as “high speed rail” or not).

(From L to R: Willie Brown, John Burton, Maria Ayerdi-Kaplan (TJPA), George Miller, Gavin Newsom, Speaker Nancy Pelosi, Ray LaHood, Barbara Boxer, Curt Pringle, and not sure who the other two are)


The California High Speed Rail Authority collected some of the remarks via their Twitter account, @CaHSRA:
Quote:
“We’re finally going to have high speed rail here in California” -SF Mayor Gavin Newsom

“The Transbay Transit Center is a bullet train for job creation” -Senator Barbara Boxer

“CA got the most HSR funding because you all have your act together” -USDOT Secretary Ray LaHood

“We need to get into the HSR business in America and there’s one way to do it: make the investment.” -LaHood

“Transbay will boost the dream of HSR in CA and across America.” -Speaker Nancy Pelosi
The CHSRA put out a press release with this quote from Chairman Curt Pringle (who probably can’t wait to have a groundbreaking in his own city of Anaheim for the ARTIC project):
Quote:
“We are all committed to building a world-class high-speed rail system and this groundbreaking signals another step in the process of making that system a reality. We’re pleased that the Transbay Joint Powers Authority has made the future development of a high-speed rail system a centerpiece of its planning for this multi-model transit center. Projects like these if done right have the potential to truly transform a city and reinvent the way Californians travel – making it faster, cheaper, more convenient and better for the environment,” said Authority Chairman Curt Pringle.
There were times in the last year or two that this day didn’t look like it’d ever come. Sure, there was always going to be a new Transbay Terminal, but the CHSRA and the Transbay Joint Powers Authority were squabbling over the details of where the station should be located. However, Attorney General Jerry Brown, Speaker Pelosi and Senators Boxer and Dianne Feinstein intervened to ensure that the existing TJPA project went ahead as the SF terminus for the HSR project and that the all-important “train box” was funded with $400 million in federal high speed rail stimulus money.

It’s good to see the HSR project breaking ground. We’ve got a long way to go, obviously, but we’ve gotta start somewhere. And here on August 11, 2010, we did.

Needless to say, this should be seen as another blow to the HSR critics and opponents on the Peninsula. As SF Supervisor David Chiu (likely SF’s next mayor, after Gavin Newsom is elected Lt. Governor this November) said at last week’s CHSRA board meeting, anyone who thinks that SF is going to let the Peninsula cut off the HSR project in San José is crazy. With HSR playing a key role in the multibillion-dollar Transbay Terminal project that is now officially under way, it seems even less likely than ever that the Peninsula can avoid HSR. Since clear majorities of Peninsula residents support HSR, despite what some city councils claim, that’s an outcome that will make most Peninsula residents very pleased indeed.

Good news, even if it doesn't necessarily mean anything.

Yeah the new transbay Terminal will be MASSIVE. I hope the 1,200 ft. tower will get going in not too long as well.

The Transbay Terminal will definitely be one of the sexiest pieces of infrastructure out there.

I just wish they would have gone with SOM's proposal.

KTX-II is rated for 330 km/hr(205 mph) service speed. The reason it has been restricted to 188 mph is because of mixed traffic issue with TGV-K, which can top at that speed. Once TGV-Ks are retired and replaced by HEMU-400X(rated at 370 km/hr service speed), the service speed should be upgraded to 205 mph.

That's only for Korea. The US proposed model has uprated motors good for 350 km/hr service speed rating.

The writer didn't understand exactly what's involved.

My question is, why would the US want KTX related technology?
After all the Acela is based on TGV which is the basis of KTX-II isn't it?
