“As I recall, the existing L or elevated trains in Chicago, have a direct line from downtown to OHare.”
You are correct. I was wondering the same thing myself as I have ridden that elevated train to O’Hare. Perhaps there is a real estate angle as that line owns a lot of valuable downtown real estate.
“Perhaps there is a real estate angle..”
But of course...and many other angles as well. Everything...EVERYTHING..in shitcago is premised on payoffs, graft, corruption, bribery, blackmail etc.
