Airo is relevant because an APV derived solution is IMO the most likely way to get dual mode diesel + electric Long Distance equipment.

If the APVs work out on Airo, when Amtrak expands the Single Level LD fleet they're likely to ask about adding dual mode capability. It's relevant on the Cardinal, Crescent, Meteor, Star, and if they already have the technology in service, why not use it and get an order of Airo 2 long distance coach equipment? Then you add in the Lake Shore Limited and etc if the NYC-Albany project eventually gets started, etc. By the time Amtrak is ready to order new single level LD equipment they'll know if Airo was a good idea or not.
 
I think you're confusing that with the future Airo trains that will be dual mode but will only be used for corridor service. They're being made by Siemens, but they're not Chargers, they're Airos, and they're a semi-permanently coupled trainset, not a locomotive. Or New Jersey Transit, which has some dual mode locomotives right now. Right now, anything that runs beyond the NEC has to change engines in either Washington or (for the Vermonter and Springfield trains) New Haven.
NJ Transit's dual mode locomotives are called ALP45DPs.
 
With Genesis locos being repainted, when will all of the Siemens orders be on the property?
The remaining ALC-42s will probably take 2-3 years to be fully delivered. After about four-ish years, we're about to see the delivery of the first 75. But there's also the Airo sets coming in which will take more time. Good thing that second facility in Lexington will be in operation soon.
 
To update on the Zephyr Charger; the unit, AMTK 341, did not stay with #5(10). I read it was dropped off at Lincoln, Nebraska. #5(12) evidently picked it up last night as Marne_KJ-80701 caught it at Fort Morgan, Colorado this morning.

 
This YouTube video took (I think) an interesting look at the new equipment being delivered nationwide. It main assertion is that the problem with the new equipment isn’t with the manufacturers but with the receiving railroads. Brightline e.g. has apparently no major issues, because they spend heavily on maintenance. My objection to the premise, if it is true, is that a brand new locomotive shouldn’t need to be shopped nightly and tinkered with. If all this technology is so great, why could equipment from the twentieth century roll off a line, enter service, run on a standard maintenance cycle, go for millions of miles, and last decades beyond expectation? Personally, if it is true, Amtrak should look to buy simple equipment with as few parts to fail as possible.

The video ignores the cold weather explanation, if it is one. Still it has interesting assertions: that Amtrak spends less (or less wisely) on maintenance than Brightline, does not have full shops at every endpoint, and has the diesel engines specified to a higher horsepower, and it describes what that does to the engine. It also says the engine should be shut down rather than idled at stops of any significant length, and Brightline always has shore power for that. HEP power to the passengers if the locomotive conks out in the wild I'm not sure is mentioned, or maybe it is along with Brightline running double-headed. (The video does mistakenly say the southern facility for Brightline is in Miami instead of West Palm.)

I'd say a diesel that saves fuel and pollutes less is going to be complex, not simple. I recently asked a service manager at a car dealership if they could still pressure test the engine cylinders on a hybrid like we did in the old days, screw out a spark plug and put a gauge on the hole. He said no.

This has been talked about here on AU multiple times before. I believe other railroads have made Maintenance contracts with Siemens for their equipment, but Amtrak hasn't, which could be a contributing factor.
