If they do install rail, I hope they take a page from history and name the first two train sets
Bluebird and
Redbird.
For some time, it has been clear that (K)MSP has been bumping up against its capacity limits as an international airport, even with the addition of a new north-south runway and expansion of its terminals. One of the congestion mitigation proposals involved a mega-airport in Dakota County southeast of the Cities, and another involves a considerably beefed-up airline presence at (K)
RST. The proposed high-speed line would link the metro area with both of these proposed solutions. Also, the Mayo Clinic and IBM are both major employers in Olmsted County - their presence and interest in high-speed travel to the Twin Cities might have a lot to do with the durability of this proposal.
Personally, I'll believe it when they start building the right-of-way in earnest.
Sipes123: yes, the Twin Cities to Duluth proposal is called the Northern Lights Express. It is proposed with a 110 mph speed limit.
CHTT1: As for HSR to Chicago, it has been agreed that it will broadly follow the Milwaukee Road trough Red Wing, Winona, La Crosse, Tomah, Wisconsin Dells, and probably Madison to Milwaukee and Chicago.
