Fwiw, I do see both Trump and Rahm as fairly seriously disposed to getting an airport express built. Whether their dedication is enough to overcome whatever the biggest hurdles will be, I have no idea, but I think they're serious about looking at it. And with the all-new ORD T2 on the cusp of planning and design, the Dept of Aviation also could direct some efforts at a possible airport express project at a moment of perfect timing. (Union Station redevelopment adds to this rare syzygy.) It could flop for various reasons along the way, but things are aligned right now more than they ever have been.
