I like your optimism.

I think any kind of GPS might help if someone is "situationally un-aware".There is no “navigation” system inside a locomotive. There is a GPS component to PTC, but you can’t strictly rely on GPS because it may not be accurate enough to identify which track you are on, and speed restrictions in many cases are track-specific (track 1 may be 70 mph, track 2 may be 60 mph, and the siding may be 20 mph in the same area).
Positive train control combines that with other information to know where you are, including which track you’re on, and that gives the engineer a heads-up about speed restrictions, including warnings if they are approaching a penalty brake application, which will apply if they go past the programmed braking curve for that particular consist type (which is designed to ensure they are at or below a given speed by the time they reach the point where the restriction applies).
Of course, that’s part of the controversy over this incident, leading to Amtrak’s decision not to return to the new routing until PTC was enabled on that segment. Had PTC been active on that stretch, the train would have gone into a penalty brake application and slowed way down (possibly to a stop) before reaching the curve.

I would bet that Siemens is going to get the Amfleet/Superliner replacement order, and I truly hope they go back to single level. I've seen the interior of the new cars and I am extremely impressed with what they're producing, and I personally think they're a shoo-in for the job.
Sharing a shell isn't really required if all the parts that need to be replaced are the same. I personally wouldn't say the trade off of capacity would be worth it and it might not even be worth it from a cost standpoint. Longer trains are heavier trains which means increased fuel consumption which might not be worth it. And if the trains are the same length, you'd be getting less revenue which definitely isn't attractive. My question, which Amtrak doesn't like disclosing to the public, is do the Accessible Rooms on the Superliners sell well enough where available? If they sell well enough, they don't necessarily need to be that accommodating. Also, the Viaggio Twin is ~20 inches longer than the existing Superliners, which would mean more room for a chair lift if Amtrak did decide to be accommodating.Bilevel cars are better for capacity of course, but there are other factors. Being able to standardize the long distance is one, but a bigger issue is Accessibility. Currently disabled Superliner passengers are confined to the lower level of their car, the Viaggio Comforts give end to end acess for the whole trainset. It would be hard (but not impossible) to pull that off with bilevels.That's a hugh deal, and I think it may be worth the tradeoff.
The problem with the existing Viaggio Twin design is it is what we would call a multi level, which would mean walking up and down stairs a bunch of times if you were to go between cars. Which is fine in Europe since most overnight trains are designed and planned so the riders don't have to move between cars. From what I've seen from travel videos on YouTube, some railways actually lock the doors between cars since there isn't a lounge or dining car to go to on some overnight trains in Europe.Here's something really interesting for you. Looking at the Viaggio Twin specs, it is only 15.15 feet high. The GG1 is listed as 15.0 feet high over locked-down pantagraphs and they of course fit through NYP. That is enticingly close. What is the possibility that a low-profile Superliner could be made or the tracks lowered by an inch through NYP (steel ties)?
One suggestion . . . add Viewliner upper berth windows to make the upper berths less claustrophobic.

I asked WSDOT's spokesperson if that means the "Wisconsin" Talgo Series 8 trainsets are not coming to the Amtrak Cascades. She replied, "They are being considered by Amtrak as an option if we need more equipment than is already here. No final decisions."
Except that ODOT will balk at the idea of their Series 8 trains being used only in the VAC-SEA-PDX part of the corridor and not on the section of the line they pay for.I hope that they can make the Wisconsin cars work in the mid-term future. 5 Talgo sets would at least allow them to operate the pre-Covid schedules. If the Bypass is used and schedule/reliability improve as expected, I think an adjustment of the schedule could be done to add 2 more round trips and better utilize the equipment. At a minimum, it makes sense to focus the Talgos on SEA-PDX and then SEA-VAC, and then use Horizons between PDX-EUG.
I agree, but it's time to make some tough choices. Ridership south of Portland has always been dismal. With University of Oregon going online this year, I think it is going to continue to stay very low. Using a 2 carriage Horizon trainset would probably serve the line. It's too bad we don't have any spare DMUs laying around. A line like this in Europe would probably have 4x per day DMU service.Except that ODOT will balk at the idea of their Series 8 trains being used only in the VAC-SEA-PDX part of the corridor and not on the section of the line they pay for.
I don’t think there was any misunderstanding.
To my knowledge, Amtrak has proposed renting the former Wisconsin sets from Talgo as part of its compensation to WSDOT for the loss of the Series VI set that was wrecked in part due to Amtrak’s negligence.
That doesn’t mean WSDOT has agreed to Amtrak’s plan. WSDOT could still negotiating with Amtrak on the details of the arrangement.
But there’s a reason why this thread title ends with a “yet.”
Ultimately, I think WSDOT and Amtrak will come to an agreement that sees the Series 8 sets coming to the Pacific Northwest.
I also think it’s going to be a temporary arrangement. I don’t believe Amtrak or WSDOT will purchase the Series 8 trainsets from Talgo. I get the feeling that WSDOT wants to be done with the Talgo maintenance agreements.
WSDOT has cash and grants in hand to buy new railcars. They’ve made it clear that they want to get on Amtrak’s (seemingly delayed) order for the Amfleet replacement. Talgo is unlikely to win that order. I’ve also heard rumors that they’ve looked into buying Siemens Venture trainsets similar to those being built for California, the Midwest and VIA’s Corridor.

DMU are in use in multi states. Oregon is/was one of them.
You can buy new or rebuild use.

They may be in use, but only because they’re classified as Light Rail or they are kept away from freight trains. You cannot share a tracks with a DMU and freight. FRA doesn’t allow it.

Sorry but not true. The Colorado Railcar DMU is certified for such use.
US Railcar is the company who bought the assets and patents from them:
