The original Shinkansen was on dedicated rail and had a maximum track curvature of 1500m 2500m (just under 1mi.) edit: Correction: 2500m. |
^^^I’ve seen the occasional call to use the N700 on a new NEC for this reason—the original Shinkansen is, by now, almost a legacy system, and the N700 was designed to reach 300 km/h on this older track (tilting trains, very quick acceleration). I’m not sure if it’s as competitive in California, though—it’s a whole new system there and should be built to a 350 km/h standard (I’m not even sure if there are any 350 km/h Shinkansen).
I’ve heard that there was some sort of big announcement with proposals for building and operating the system came out, specifically mentioning Alstom and Virgin as being among the potential bidders. Does anyone have a link for this? |
Ah, here’s what I was mentioning—from California’s HSR Authority:

The N700 (Nozomi Service) actually maxes out at 270km/h on the original Tokaido portion of the Shinkansen. This is the portion between Tokyo and Osaka that was originally designed for a max speed of 200km/h. It has a minimum track radius of 2500m. I believe that these trains are some of the quickest to accelerate as well. A often-overlooked important fact when you are running in highly populated areas. On a newer portion of Shinkansen, the Sanyo Shinkansen that runs between Osaka and Kyushu they run trains at 300km/h. It has a typical 4000m track radius. It can potentially run much faster in the future. The newest line, the Hayabusa service on the Tohoku Shinkansen will run at 320km/h. These are the newest E5 series. I'm not sure the track radius, but that line was planned to run at 360km/h. They just couldn't get the train quiet enough at that speed. To put this in perspective, China's new 350km/h lines typically have a minimum 7000m track radius. California is planning, I believe, for 6500m. As alluded to before, part of the reason that trains don't run as fast in Japan is the tunnel boom effect and the number of tunnels that are close to populated areas. Japan has the strictest noise pollution laws (for trains at least) in the world. This combined with the inefficiency at higher speeds and the number of tunnels made faster speeds impractical. Remember, these trains are running every day, all day, sometimes at frequencies of every 6 minutes on some lines. Japanese companies are one of the parties that are interested in the High speed contract for California. In my opinion, their experience with earthquakes and their strong desire to export the technology make them one of the better candidates for the California System. As for the North-east corridor, it probably wouldn't be a bad idea to consider the N700 series, although I'm sure there will be excellent competition for that sector. Personally, I'd love to see German, Canadian or French technology in the NEC and Japanese technology in the West. The US should try to get a mixture of technology, just as China has done. |
High-speed rail: First phase could run to Merced after all (Merced Sun 3/28/2011)
High-speed rail: First phase could run to Merced after all
Authority plan to apply for money Florida rejected would expand construction project's 'backbone.' By KEITH A. JONES Merced Sun 3/28/2011 "High-speed rail may come to Merced sooner than expected, as the California High Speed Rail Authority will announce today it's asking for $1.2 billion in funding that was rejected by Florida. If the request is approved, it would mean the first phase of track will run from Merced to Bakersfield. Also, instead of building a station just in downtown Fresno, stations will be built in Merced and Bakersfield. The authority is also looking at building a station in Tulare County. "This is very good news for Merced," said Mayor Bill Spriggs on Sunday afternoon. "The City Council has always supported high-speed rail. We were disappointed when the Corcoran-to-Borden route was announced." "If we get a portion of Florida's money, we'll able to complete the entire backbone of the project," Jeff Barker, deputy director of the rail authority, told the Sun-Star Friday..." http://www.mercedsunstar.com/2011/03...ase-could.html |
A backbone from Bakersfield to Merced would be a real turning point for passenger rail in California. Even in the worst case scenario in which the new separated trackage ends up serving conventional passenger rail, it would still speed up both Amtrak and freight trains significantly.
|
Yeah, but won't this section be just track? No actual HSR service?
If so, then why not use the money, not for the Fresno-Merced extension, but instead to start HSR service between Fresno and Bakersfield? |
any other states about to reject funds?

Wait, so they can't instead use the money to start HSR service between Fresno and Bakersfield?

Huh? Service will commence as soon as the track is finished. CHSRA has not yet worked out the details - the "service" might be Amtrak running at 110mph (top speed of the P42 locomotive) or it might be TGV or Shinkansen trains running at 220mph.
|
Quote:

The P42 is the GE Genesis diesel—there’s been some talk of running the San Joaquin along the new tracks at 110 mph as a stopgap measure, though I’m not sure if this is doable due to their weight—CAHSR’s tracks will be designed to carry lightweight high-speed trains, not FRA-compliant tanks, so I’d be afraid running diesels might cause undue wear on the rails, forcing the tracks to undergo some pretty heavy repairs before eventually opening for actual HSR service. Anyone know anything more about this?

California’s really going for it:

I'd like to see it all go to California. I like to focus things down and get them built, one by one. It appears time to focus down on California's HSR and get it built.

Hey, does anybody have any thoughts about what kind of trains America are going to build for this new track? Will they look like Shinkansen or French trains?
This is going to be good for the US to enter into this new area of train building. |

in this article, it makes it sound like the money will divided up:

There is a total of $2.43 billion to be reallocated: $1.63 billion from the stimulus funding which does not require state marching and $800 million from FY2010 funding which does require a minimum of 20% state match. California will not get it all. Too many other projects and the NEC which would use additional funding as well. It is will be interesting to see how the FRA and LaHood divvy up the funding. |
I don't mind California not getting all of the funds. There are just too many projects around the country right now. That said, it should get the lion's share, IMO.
|
Did we find out what kind of train their using? I was hoping for more Reginas to be able to run on this california railway system, honestly. Shinkansens, I thought those were a restaurant.

The county that refused BART back in the day now wants to derail bullet trains to San Francisco. It's really hard not to hate San Mateo County sometimes.

Gotta love the obnoxious NIMBY's, eh? What the hell is wrong with San Mateo County? They always seem to be the problem when it comes to the Bay Area and transit improvements...

Why do I get the feeling that California's HSR will be a Fresno to Bakersfield segment ("HSR to nowhere"), and everyone will point out how dumb California is.
If HSR does NOT go to San Francisco, it is a complete waste. I'm on the fence already as to spending $50 billion or so to get from L.A. to S.F. maybe 15-30 minutes faster than by air. And that is a BIG "maybe". Plus airlines (read: Southwest) will still likely offer a cheaper ticket. Connecting in San Jose to a CalTrain from HSR would be like flying from LAX to SFO and changing planes in Stockton. Yes, you could do that, but why would you want to? |
a small peninsula of nimby idiots isn't going to derail a massive rail project that was approved by a super majority of voters in ca.
|
Yeah, I'm not ready to write this off yet. The powers-that-be in SF city will take on these hick NIMBYs--there's way too much at stake to let some selfish asshats derail such a critical piece of infrastructure.
Seriously, the arguments just don't wash. Don't want to hear trains? Then don't move next to a 150-year old railroad. It's not like anyone can claim they predate the trains along that right of way. |
Quote:
Will the trains be going at full speed through urban areas? Would this make them substantially louder than Caltrain as it is? |

I agree. I find the arguments and NIMBY reactions I read about on-line about converting the existing rail corridor to a fully grade separated, electrified corridor to be ignorant and often silly. It will be quieter, improve safety, and provide HSR access to most of the major cities in CA to boot. Should be a no brainer. |
Haha, looks like some pressure was brought to bear overnight: the NIMBY politicos are "clarifying" their statement in today's Chronicle:
Peninsula legislators update position on rail Chronicle staff report San Francisco Chronicle Thursday, April 21, 2011 Three Peninsula legislators now say they don't think a proposed high-speed rail line from San Jose to San Francisco should end in San Jose, clarifying remarks they made earlier this week. In a joint statement, Rep. Anna Eshoo, D-Palo Alto, state Sen. Joe Simitian, D-Palo Alto, and Assemblyman Rich Gordon, D-Menlo Park, said they thought high-speed trains should run up the Peninsula at a lower speed on current Caltrain tracks. ...

The route selected seems to defeat the purpose of a high speed rail.
It should go straight from San Diego to LA to San Francisco. What is the point of going twice faster if you take a twice longer route? |
Quote:
The LA to San Diego Inland Empire route is perhaps the most controversial but the decision was that there were too many physical constraints in a direct route from LA to San Diego. All extensively studied over a number of years. Besides the population of the Inland Empire region has grown enormously in recent decades. So the main route is planned to swing through or by the Inland Empire cities. The Surfliner trains - with improvements to the existing LA-SD route - will provide options for those traveling from San Diego to LA. I have also noticed that the planned route of the complete CA HSR system will also provide for convenient connecting HSR corridors to Las Vegas (from Palmdale) and to Phoenix AZ (from south of Riverside). Don't know if this was a complete accident or part of the background thinking on the selection of the route while they could not publicly push for or propose future extensions to those out of state cities. If you want to read the studies and EIS reports to see the details and how they got to the current planned route, there are a ton of documents on the CHSRA site at http://www.cahighspeedrail.ca.gov/library.aspx. |
The Washington Examiner, a hack/propaganda 'newspaper' had an anti-high speed rail screed in yesterday's paper by a hack at the Hudson Institute. Anyone who describes Karl Rove's group as a 'non-profit advocacy group' immediately loses credibility. To paraphrase cirrus, Ms. Furchtgott's thoughts on high speed rail and transportation should be taken about as seriously as Lady Gaga's thoughts on astrophysics. Here is my response to this drivel.
"Your propaganda in yesterday's Washington Examiner is deeply flawed. First, Crossroads GPS is hardly a 'non-profit advocacy group.' We both know it is a group formed by karl Rove this past election cycle after the Supreme Court's CItizens' United decision to funnel unlimited campaign contributions from hedge-fund managers and other wealthy oligarchs to candidates. Second, has any cost/benefit analysis been done for our interstate highway system? User fees (i.e. the gas tax) only pay for 51 percent of the cost of construction and maintenance: http://subsidyscope.org/transportati...hways/funding/. Additionally, the federal Highway Trust Fund has needed bailouts of $7B - $8B each of the past four years. This is a significant subsidy of motorists at the expense of the general population-- well over $30B in the past four years. Since 2008, slightly over $10B has been appropriated for investments in passenger rail. The subsidies for roads and driving is even larger when you look at county and local roads. Many of these roads are paid for through bonds, sales tax, property taxes and other sources of revenue that have nothing to do with driving, meaning auto use is subsidized. Parking is also a huge subsidy for motorists, regardless of how you travel. Donald Shoup estimates the subsidy for parking each year is $127B (http://www.nytimes.com/2010/08/15/bu...my/15view.html). High speed rail compares even more favorably when you look at the externalities of driving. Every single year, there are approximately 35,000 - 40,000 auto fatalities in the US. In addition to the tragic human toll this costs our economy $160B every single year. High speed rail, on the other hand, is one of the safest modes of transportation. Since the Shinkansen began operating in Japan in the 1960s, there has not been one fatality on high speed rail in that country. You also compare high speed rail to intercity bus, and again, your comparison is deeply flawed. According to Amtrak's plans for investment in mobility in the Northeast corridor, passengers will be able to get from DC to New York in just over 90 minutes (http://www.thetransportpolitic.com/2...o-be-realized/). Bolt Bus and other intercity buses, on the other hand, have to share the highway with all the other vehicles and trucks. Travel time by bus currently takes four hours or more. It is not unreasonable at all to expect there are a lot of high wage earners that will gladly pay more for a trip that is one-third the travel time as bus. This is also current travel time. The population of the United States is expected to increase to 400M people by 2050. Is there anyone who doesn't seriously expect our already-congested highways to become even more crowded and for travel to take longer as all these additional people drive? The level of comfort on high speed rail also far surpasses that offered by bus. High speed rail offers wider aisles, wider seats, wireless internet (as offered on some of the buses), more comfortable restrooms, and dining options." No cost-benefit studies done for Obama's $53 billion high-speed rail boondoggle http://washingtonexaminer.com/opinio...ail-boondoggle |

202 Cyclist--a minor correction, but I'm pretty sure Bolt and Megabus have a five-hour run from NY to DC. (2 hrs from Philly to NY; 3 hrs from Philly to DC--my origination point is Philly so I can't take nonstop run, however.) Running the full length of the NJ Tpk instead of following the Delaware Expwy. will only cut a marginal amount of time off. |

As part of the sale of the tracks, there is a clause that the lease to UP could be terminated for "substantially enhanced and upgraded grade-separated passenger services" - it's what is known locally as the "BART clause," because it was assumed at the time that BART could potentially be expanded down the peninsula at some point. CHSRA has never talked seriously of exercising the clause in large part because they want to work with UP in other areas of the state where UP owns the best ROW, but it's always there as an option (and IMO should be used to significantly decrease the cost of grade separation up and down the peninsula - keeping the grade separations available for freight use means much lower grade increases/decreases, larger portals, higher catenary, and mega $$$, all for a few night trains a week). Also - Caltrain already received an FRA waiver to run non-compliant trains in the corridor even if freight trains remain - it's a time-sensitive waiver with freight trains running only in the middle of the night (not even every night, just a few trains a week as exists now). That ruling from the FRA last year was considered the best news for passenger rail in decades. |
Quote:
But, I believe many on the peninsula are over reacting to elevated tracks. They want grade separations so traffic isn't waiting at crossings for the trains, but only if the tracks are laid under city streets. While I'll admit elevated tracks aren't beautiful, they sure are functional. TRE on new elevated tracks over an intersection at Beltline Road in Irving That was a diesel locomotive @ 60-79 mph, an electric locomotive woud be much quieter. By the way, looks like the folks up in the Peninsula are looking at doing what Orange county wanted, using the existing rail corridor at slower speeds. CHSR had not planned on going 200 mph in either locale, so the need for a new grade separated corridor decreases. Along with the decrease requirements comes decreased costs... |
If CAHSRA wants trains to go faster than existing Baby Bullet services, though, they’ll need overtakes in some places, and there’s no way California will allow four-tracked at grade intersections with trains going at 90 mph.
As a short-term compromise, though, this isn’t so bad—note that the original TGVs to Lyon ran along a shorter LGV (high-speed line) than exists now, making for a ~4-hour trip. There was enough dedicated high-speed track to demonstrate the difference between high speed and conventional rail, though, which helped convince people of the project’s worth. |

Instead of this, side platform 1 track 1 track 2 side platform 2 Build this track 1 Caltrains island platform 1 track 2 CHSR track 3 CHSR island platform 2 track 4 Caltrains You don't need quad tracks over the entire distance. |
This blog post suggests that there is a slight difference between the dynamic envelopes of Caltrain and CHSRA (namely, platform height) which would make it slightly more expensive to design island platforms which serve both services, though...
As it is I doubt UP would want to lose any customers...they would only want to cease operations on the line were all their customers to shut down. Although it's quite critical of CHRSA, the blog Systemic Failure is also quite insightful. Following that blog's stresses, a long-term issue we must endeavor to work on is an adoption of an international rail safety standard--one not based on weight they way it is now. Similarly we need to import European auto safety standards here straight stat. |
Does anybody have a rough estimate on how much speed (both average and top) would be lost as a result of sharing tracks with Metrolink/Caltrain?
And I want real answers, not biased ones from track-sharing booster forumers. I just hope one day the whole corridor can be grade-seperated on it's own track. Hopefully it doesn't become one of those VERY ANNOYING "the route is too busy to build a new track, and construction would disrupt existing services" situations. I can easily see this happening. |
