Bullet train's first segment, reserved for Southland, could open in Bay Area instead

Read More: http://www.latimes.com/local/lanow/l...123-story.html

Quote:
A valuable perk handed to Southern California from the bullet train project — a 2012 decision to build the first operating segment from Burbank north into the Central Valley — is being reconsidered by state officials. The state rail authority is studying an alternative to build the first segment in the Bay Area, running trains from San Jose to Bakersfield.

If the plan does change, it would be a significant reversal that carries big financial, technical and political impacts, especially in Southern California. --- “You can’t ignore Southern California or Los Angeles or Orange County and say we are going to go north, period,” said Richard Katz, a longtime Southern California transportation official and former Assembly majority leader. “It made sense to start in the south, given the population and the serious transportation problems here.”

The original decision to start the initial segment in Burbank was considered a major economic benefit to the region, providing commuters with 15-minute rides to Palmdale, a connection to a future Las Vegas bullet train and an early link to the growing Central Valley. --- But the state is facing major difficulties with the south-first plan. By building in the north initially, the state would delay the most difficult and expensive segment of the entire $68-billion project: traversing the geologically complex Tehachapi and San Gabriel mountains with a large system of tunnels and aerial structures.

With the project already behind schedule and facing estimates of higher costs, the Bay Area option could offer a faster, less risky and cheaper option. Getting even a portion of the project built early would help its political survival. --- The outcome of the new evaluation will be known in the coming weeks, when the state unveils its 2016 Business Plan. The document will be the most comprehensive update for the $68-billion program in four years. A decision to drop its plan to start the system in Southern California will not be popular among area civic leaders.

High-speed rail construction extended northward in Madera County

High-speed rail construction extended northward in Madera County

By Tim Sheehan
Fresno Bee
March 8, 2016


Work continues on a high-speed rail viaduct, or elevated bridge, over the Fresno River next to the BNSF Railway freight trail tracks east of Madera. It is part of a 29-mile, $1 billion construction contract. A $154 million change order to the contract will extend work north of this site to about Avenue 19. (Image courtesy of the Fresno Bee).


"The California High-Speed Rail Authority has given a green light to a $154.2 million extension of its first construction contract in the San Joaquin Valley, stretching the line northward by almost 3 miles in Madera County.

Meeting Tuesday in Sacramento, rail authority board members voted to allow managers to negotiate a change order with contractor Tutor Perini/Zachry/Parsons for Construction Package 1, a 29-mile section of the rail line from American Avenue south of Fresno to Avenue 17 northeast of Madera. The original contract was awarded in mid-2013 at a cost of about $1 billion. The change order extends the construction to about Avenue 19, near Madera’s Amtrak station.

Scott Jarvis, the authority’s chief engineer, said extending the construction segment “advances the work towards Merced on an environmentally cleared section and provides the capability for a more logical connection and transfer point near an existing Amtrak station.”

Madera’s Amtrak station is along the east side of the BNSF Railway tracks just north of Road 26. Jarvis added that the section was included within the Merced-Fresno environmental impact report that the authority and Federal Railroad Administration certified in 2012..."

State revises proposed bullet train routes, but San Fernando Valley communities remai

State revises proposed bullet train routes, but San Fernando Valley communities remain skeptical

By Ralph Vartabedian
LA Times
Mar. 17. 2016


The mountainous area above the Tujunga Wash in Sunland is one proposed route where engineers would bore a tunnel for the bullet train on the Palmdale to Burbank Alignment. (Luis Sinco / Los Angeles Times)

"The California rail authority has proposed major bullet-train route changes that would put more of it underground as it crosses the San Fernando Valley, avoiding some of the impacts of above ground routes that have drawn strong protests.

High-Speed Rail Authority Chairman Dan Richard said Thursday the state is committed to mitigating the effects on low-income communities as a matter of "environmental justice."

After a public meeting held by the San Fernando Valley Council of Governments, it was clear that the new plan would continue to receive resistance from the communities, even though it would avoid bisecting neighborhoods in several cases..."

By 2030 we'll probably be able to 3D print a Hyperloop for a fraction of the cost, this system seems like a huge mistake...

Or planes may generate far less noise, enplane and deplane in half the time, for "short" hauls be able to take off and land on shorter runways, cities continue to grow closer and around airports, headway between flights is reduced, etc and maybe it won't be viable.

The Hyperloop's problems have been well-described:

https://pedestrianobservations.wordp...-entrepreneur/

https://pedestrianobservations.wordp...perloop-costs/

I wonder if part of the reason that maglev development hasn't been as rapid as it "should be" is because, once you pass HSR, you're in the realm of diminishing returns in terms of the buildout cost? In order to have truly high speed rail you must have a quite straight ROW. And as you get incrementally faster from ~200 kph, you have to use exponentially more expensive mitigation techniques against air drag. That doesn't go away with maglev vehicles. (It does, of course, with hyperloop ones, but there are other issues with the capsule system that need addressing.)

This thread is explicitly not about hyperloops or airplanes. Stay on subject, folks.

Jesus. $50M per mile as a marginal cost? No wonder this project is so difficult to pull off.

This is presumably on flat land in a rural area....

The additional work includes several grade separations and a bridge, IIRC.

3 miles for $150 million sounds pretty darn good to me. Or, approximately $50m per mile. This is relatively right in line with expectations. Granted, the additional work involves civil stuff and does not include rail or traction power.

For comparison, bored tunnels are close to $500m per mile, aerial viaduct $200m per mile, and easy at-grade at $25-$50m per mile. The latter range, from my observations, is relevant to the necessity to purchase land or not.

Work starts soon on high-speed rail trench into downtown Fresno

Look at this! Investing in modern, efficient, sustainable transportation is creating good construction jobs here in the U.S. It is unfortunate that there are some who'd rather have people sit at home, unemployed, than invest in modern infrastructure.

Work starts soon on high-speed rail trench into downtown Fresno

"Motorists on Highway 180 through downtown Fresno will start seeing the effects of high-speed rail construction in July as crews begin building a trench that will take the bullet-train tracks beneath the freeway.

The 40-foot-deep trench is the first underground construction for California’s high-speed train system. The two-mile long trench, from Roeding Park to about Stanislaus Street in downtown Fresno, will go under the freeway as well as a San Joaquin Valley Railroad line and an irrigation canal.

The California High-Speed Rail Authority reports that the initial work will include improvements to the shoulders of Highway 180 between G and H streets..."

I like the idea of high speed rail in California. But its been so muddied and thrown against the wall so many times, I don't know what's true and what's not anymore. That being said, the one thing I know is true is the total price tag.

This is a serious question.

I know some sections will be viaducts and as stated above will be trenched and tunneled. But why are even the flat land sections costing so much per mile? And why is the new plan all of a sudden avoiding LA for the time being? the biggest mistake seeing how they will be missing out on 20+ million potential riders.

The project is so large, and funding requirements so costly, the best and appropriate method to deliver it would be in phases.

The is first because sections of long tangent track are necessary for testing trains. It also supports the need to provide a maintenance yard at relatively cheaper costs than in LA or SF areas. It also compliments political support whereas vetting extensions to north and south can be equal, if paired together.

Like you said, it doesn't compliment initial ridership and usage, which is a consequence.

IMO, too much in politics is playing a role in the planning of the system. I agree with the initial operating criteria identified in the State voter approved measure, however, not much of the later political involvement. The product will be slightly less optimal operationally and slightly more expensive - capital construction and annual operating costs.

Yes, the CHSRA blog site is good.

So which is it: should they run roughshod over the concerns of residents (e.g. many of the same voters who approved the bond measure), or should they actually accommodate these concerns, within reason?

Those are mutually exclusive, discrete choices.

Courtesy of sf.streetsblog, a video, photo, and map of California High Speed Rail. A fully-funded 119-mile corridor has begun construction in the Central Valley. This first segment of CAHSR will eventually connect with the Pacheco Pass segment, and link Fresno with the Bay Area:

CA HSR construction

One of my friends who works for Parsons Brinckerhoff took these photos of high speed rail construction in Fresno. This important investment in efficient, modern, infrastructure is creating good jobs an will help encourage infill development in cities like Fresno.
