Here I am with what is (probably) more official info than my last post:
1. According to All Aboard MN, citing a WisDOT presentation at the Wisconsin Association of Railroad Passengers' early February 2024 meeting, this service will be named the Borealis (not the Great River, as was previously stated/shared)!
2. Operating agreements may be *finally* nearing completion, apparently. Of course, this remains to be seen, but it bodes pretty well for this service at least starting in the late spring, knock on wood. Will be pretty surprised & pleased if it starts before May at this point.
3. An "Amtrak contact" (classic to have the details trickling out like this, ha) has apparently told AAMN that the Borealis will use refurbished Horizon cars. This does seem likely to be true as it dovetails with other bits and pieces of info I've heard trickling out over the past year, plus what we know about railcar availability out of Chicago.
Here is the link to AAMN's Quarter 1 2024 newsletter; scroll down to number 3 to see the info they provided:

I couldn't immediately locate the presentation that AAMN is citing, but I assume it may be on YouTube if someone wants to dig.
