CHSRA, Palmdale announce partnership to advance Palmdale station planning

Antelope Valley Times
July 12, 2021

"The California High-Speed Rail Authority has entered into an agreement with the city of Palmdale to supply matching funds for a grant application to the U.S. Department of Transportation’s Rebuilding American Infrastructure with Sustainability and Equity (RAISE) program. If awarded, the grant will support completion of the city’s Station Implementation Master Plan.

The Authority is requesting a $1.35 million RAISE grant to fund development of the Master Plan for the integrated, multimodal future Palmdale high-speed rail station. The RAISE funding would enable the Authority, in close collaboration with the city of Palmdale, to advance conceptual design of a world-class rail and transit center in downtown Palmdale.

“We are committed to bringing clean, electrified high-speed rail to Southern California,” said Southern California Regional Director LaDonna DiCamillo. “We are actively working with our local partners on projects such as this, aimed at bringing short and long-term benefits to millions of Californians. High-speed rail service was always envisioned by voters to connect riders across Southern California and statewide – this partnership is another step in making that happen.”

This is so vague (plus they posted what I believe is a San Jose station rendering):

The Palmdale Station will serve as a connection point for California high-speed rail, Southern California Regional Rail Authority (Metrolink) and Brightline West, creating a seamless connection between California high-speed rail and Brightline’s planned high-speed rail service to Las Vegas via Palmdale.

How do they define "seamless connection"? Having to board a CAHSR train and then transfer to a Brightline/Virgin/Blue Origin/Pets.com train in Palmdale isn't "seamless", even if they build flying crossovers and you're able to walk across an island platform to a Las Vegas train that leaves 5 minutes after CAHSR arrives.

The LA>LV scheduling will be odd in any transfer scenario since CAHSR express trains, which will not stop in Palmdale or travel on any shared LVHSR track, will nevertheless influence the Las Vegas schedule.

Any HSR system like what is being built has 12 time slots, per direction, per hour. But a system as complex as CASHR will be at full build-out means express/skip-stop/local won't progress in the same order during differing hours with similar service levels. This means some Las Vegas-bound trains won't have enough room for everyone who seeks to transfer but another leaving just 10 minutes later might only be a quarter-full.

Yeah that rendering is super old, probably not Palmdale and pretty lazy on the newspapers part. I'm not sure it ever said, but I always associated the rendering with Bakersfield.

EDIT: Actually it may be depicting SJ Diridon

Seems like capacity issues are a good problem to have IMO…. I'm finding it hard to believe that you would encounter such problems, but I suppose it's possible in a few generations after the CAHSR system is completed.

Designing a true 3-legged station is very difficult, certainly if you want the station near downtown. You're always gonna have a right-way transfer (which can be through-routed) and a wrong-way transfer where people need to change trains. Or you can do a T-shaped station where all Vegas passengers need to change trains. Possibly you can address the issue of wrong-way transfers with a reversing move out of the station, but this would constrain the capacity of the system. Or a turning loop, but good luck finding that much real estate near downtown Palmdale. A lot will depend on the alignment of the High Desert Freeway and where it enters Palmdale... Brightline is just piggybacking on LA Metro's freeway alignment.

Also can someone explain to me why all the emphasis is on Palmdale and not Lancaster? Palmdale seems like a relative backwater, with no downtown to speak of. Lancaster has a mature downtown with a great, walkable main street. Palmdale has aerospace jobs, I guess?

[Busy Bee]

Aside from the impossible current politics, why isn't Brightline West just part of CHSR again? I have a sneaking suspicion that in 20 years it will be.

I looked and Palmdale and Lancaster have approximately the same size population (my condolences to the 300,000 people who live in these two cities) and Palmdale is closer to the LA basin.

Additionally, LA World Airports (LAWA) owns the airport at Palmdale, which has three long runways. For decades LAWA has wanted to turn the Palmdale airport into another international airport for Southern California, with it served by high-speed rail. I guess dreams die hard.

In theory, the improved signaling enabled by various new technologies should enable HSR trains to operate closer to one-another. Depending on which article you read, HS2 in England will have 14-18 trains per hour. If we get well north of the old standard of 12 trains per hour, then there will be plenty of capacity for a few LA Union to Las Vegas trains per hour, even in the event of the full CAHSR Phase 1/2 build-out.

Another thing I just thought of is that having trains travel from Las Vegas to NoCal via a wye north of the station is possible, but having them stop at the Palmdale station would require extravagant trackwork to the south to avoid a backing movement. More likely I'd expect any train on this route to simply skip the Palmdale location. But like so much about Xpress West/Brightline/Virgin, we don't hear specifics.

Brightline has previously completed construction and actually run trains (on a much smaller budget!)

It looks like this is the plan, yes:
https://hsr.ca.gov/wp-content/uploads/docs/newsroom/maps/Palmdale_Station.pdf

The High Desert Corridor will link to the HSR mainline north of downtown Palmdale, with a connection pointing south only. A north connection is contemplated as well but seems to be a lower priority - its inclusion in the EIS means it can be built without additional environmental work in the future.

The more recent plans in the Final EIS confirm that the downtown Palmdale section will be 6 tracks of HSR, with express HSR in the middle, local HSR platform tracks outside of that, and High Desert Corridor tracks on the outside with a cross-platform connection to the local HSR trains. Plus two tracks for Metrolink to the east of that, so 8 tracks total.

I will repeat that it is absurd to place such a huge transit hub less than 1 mile from this:

I sure hope there are some highrises included in that station plan.

Thanks for the link.

Various online sources peg the Palmdale/Lancaster/Antelope Valley combined population at 475,000-500,000. This puts it at the same level as Fresno - so while not a big area, a bit more significant than most assume.

The full build-out of CAHSR and LVHSR will make this a much more practical area to live in the future than it is now. What's crazy to think about is if it becomes too big there will be a push to have CAHSR express trains stop there in order to shorten the travel time to/from San Jose and San Francisco, to the detriment of LA<>SF travelers.

I'm not arguing the need for a station in the Antelope Valley somewhere, I just don't get why you'd choose Palmdale over Lancaster. The whole region is a sprawly mess, but Lancaster is the most established center and the only area that even remotely resembles urbanism.

Fair enough. Lancaster has a far more significant downtown than I thought it did. When I grew up in Southern California 20 - 30 years ago, both Lancaster and Palmdale were mostly tumbleweed and either mobile homes or planned communities.

[Busy Bee]

It seems to me the driving force behind the Palmdale station choice is the fact that at least some Las Vegas HSR trains (who knows what it will eventually be called, and furthermore who will be operating it) will eventually be routed to LAUS. A LV bound train would be going that much out of it's way to reach Lancaster(if it was the CHSR station instead of Palmdale) and north of the designated High Desert Corridor.

Lancaster actually won design awards for their downtown... a lot of the denser development is newish.

So there is hope for Palmdale, but they have to WANT a downtown like this or it won't happen. I'm not optimistic.

CA High-Speed Rail Authority Approves Plan for Connection into L.A. County

Bakersfield to Palmdale EIR approved, readying the section to catch potential infrastructure funding

Joe Linton
Streetsblog California
Aug 20, 2021

Yesterday, the California High-Speed Rail Authority approved the final Environmental Impact Report/Environmental Impact Statement (EIR/EIS) for the 82-mile $19.7 billion Bakersfield to Palmdale section. That segment would bring high-speed rail into northern Los Angeles County.

The CAHSRA currently has 119 miles of high-speed rail under construction through California’s Central Valley. That initial Central Valley segment will operate between Bakersfield and Merced, with conventional-speed rail connections to San Francisco, Oakland, and San Jose. HSR will reach San Francisco directly some years after that.

From Bakersfield, building south requires crossing the Tehachapi Mountains, which isn’t easy or cheap. The plan calls for nine tunnels, totaling over ten miles, and fifteen miles of aerial structures. See SBCA’s 2020 interview for more Bakersfield to Palmdale rail details.

I'm surprised no stop closer to Mojave since that's where the space port is.

it's time for our annual update from John at The Four Foot! (who should be on the CHSR PR payroll . . .). This one is an overview of the progress in the last 10 months and he also has a link to a google spreadsheet listing all the projects in CP 1-4 and giving a status update from last year.

California's obnoxious governor recall provision is going to be an ongoing hurdle to the completion of this project. Assuming that Newsom keeps his office, he's going to have to lay low until his second term to back this project - as will all future governors.

Depends on his margin. Sleepy Dems appear to have woken up in recent weeks and Elder is claiming the election is rigged already because his odds have soured. With the spending bills on the front burner in DC if Newsom pulls out a handy win I don't think that's a recipe for timidity.

This video is depressing, imo. There is still SO much to do to even get phase 1 open, which basically connects nowhere to nowhere. How do we have so little to show for this project that's been underway for so 🞵🞵🞵🞵🞵🞵🞵 long?

I know the environmental clearance and subsequent BS lawsuits slowed it down considerably, but even still, it seems absurd to have such a little amount done. This in a flat, rural part of the line. Getting it to SF or LA seems to be a pipe dream given the current project progress and budget. Ridiculous.
