Much as I enjoy my visits to hear the Detroit Symphony,
I have two words of advice for those who hold that an Amazon HQ2 could be built using MCS as the catalyst for such;
forget it.
As this Fair Use quotation from the linked CNBC article notes, Amazon wants 500K Sq Ft - doubt if it's there in the existing MCS structure:
..The company said its new second headquarters would initially need more than 500,000 square feet and up to 8 million square feet beyond 2027.
From the "Box Score" within the article, the only Amazon criteria Detroit meets is an international airport (even if it's more Delta's "change at Jamaica" than anything else). The absence of World Class university is questionable. This Illini will certainly give the Wolves credit for being that - and it's only forty miles away.
I still hold Detroit's best hope for success is to reduce its "Corporation Footprint" from the present 105 Sq. Mi. to about 60. That's big enough for the present 715K population. What happens to the area abandoned is what happens...urban farmland, some new incorporated municipalities, prairie....fun to speculate.
Finally, to close rail related, mass transportation is an Amazon criteria, but intercity rail is not. Just recognition of "Facts of Life", or a significant omission?
