It is hard to tell but the span over BNSF certainly is wide. Seems at least possible 4 tracks wide under the span. Or maybe giving some room if a possible BNSF derailment? It is no wonder the costs for CA HSR is so expensive.

A though about the HSR bridges. Are the bridges all using the same type and length of spans. Otherwise the problem of service interruption due to a bridge failure for whatever reason (derailment, truck hitting span, earthquake, etc.) will mean a long wait for a unique replacement. Standard spans would mean storage of extras for the eventual need.
The CAHSR is going under the bridge -- that bridge is being built to take a road that used to have a surface crossing with the BNSF over both the CAHSR and the BNSF.

A couple of observations:

-Do Alstom and Siemens have the manufacturing capacity?
-2028 for the prototypes, but it seems doubtful that the segment will be open
California High-Speed Rail one step closer to acquiring nation’s first 220 mph trains
A breakdown of what manufacturers will need to provide the CAHSR if selected to build its trainsets. (CAHSR)
Six electric trainsets capable of operating at speeds of 220 mph will need to be built, including two prototype trainsets for testing and trial running. Four will be deployed in the 171-mile “Initial Operating Segment” connecting Merced to Bakersfield.

The prototypes will need to be delivered by 2028, with the other four arriving by the time the Merced-to-Bakersfield segment nears operation. All trainsets will need to be tested to reach speeds of up to 242 mph, the Authority said.

2 trains by 2028 seems doable to me.

The bigger question is that the performance requirements for these exceed anything that's currently shipping, and their total order is for a massive…6 train sets?

Seems like a lot of squeeze for very little juice.

Siemens is offering the American Pioneer 220 and is building a new factory in NC that should allow them build the train in CA. Siemens seems to be thinking that they can modify the existing Velaro Novo design.

I can't tell what in Alstom's portfolio is their proposal, but I'd be surprised if it wasn't based on their Avelia platform.

The Velaro Novo designs for Europe have a in service design speed of 360 kph ( 223.69 mph) and the Alstom Avelia has a design speed of 350 kph (217.48 mph), which makes me think that CAHSR's 220 mph for regular operations requirement is achievable with existing designs.

That pretty much sums up CAHSR as a project, no?

At the speeds these trains are planned to operate it seems like 6 trains should enable an hourly service over the initial operating segment, even if one train is in (un)scheduled maintenance. (I am presuming the prototype trains will be modified after initial testing to be indistinguishable to passengers from the production trains by the time the IOS opens.)

Yes, Federal funds were used (I understand this will also be true of the Brightline West equipment).

Thanks for the insight about Siemens, glad to hear it.

As far as Alstom, maybe they should try to deliver at least one Avelia trainset successfully first before signing up for any more new projects.

Ca HSR Authority released tentative interior designs today on book of faces.

As we move closer to buying trainsets, we're considering multiple seating options for high-speed rail passenger service. Here's a look at a few preliminary seating designs, in order:

💺 Premium
💺 Cocoon
💺 Compartment
💺 Comfort

Seems kind of weird to be replicating airline style lie flat seating when the whole premise of this train is that you don't spend a lot of time on it

I can't imagine many people needing anything but "comfort" seating for such a short trip.

Yesterday CAHSRA had a “dog and pony show” in Bakersfield.

The California High Speed Rail Authority’s board of directors supported new recommendations for a planned rail segment between Los Angeles and Anaheim, clearing it for a critical environmental review after the initial proposal received pushback from the community.
Recommendations for the 33-mile rail segment from Los Angeles to Anaheim includes four mainline tracks that would be used by the bullet train, other passenger rail and BNSF freight trains. It eliminates the initial plan to develop a freight facility for BNSF, which owns the railroad stretch from Los Angeles to Anaheim, in the city of Colton that would have housed trains not in operation. The idea received pushback from the Colton community and from BNSF.

The recommendations include a train maintenance facility at either E. 15th Street in Los Angeles or E. 26th Street in Vernon, at-grade crossings in Anaheim where the highway and high-speed rail line would be level, and no intermediate stations. The proposed line would include underground, above-ground and surface-level portions.
