I feel that plan screws over locals (and the thousands of O'Hare employees that take transit to work) in favor of out of town business travelers. Or at the least, that's how critics will sell it and it will be dead in the water.

You other plan of adding 2 more tracks to the I-90 median that connects the NCS line to the Blue line O'Hare subway station would be the best solution, and while the median trackage could be fairly easy, tunneling to the station and then expanding said station will be very costly. The flyover trackage connecting the I-90 median tracks with the NCS line wouldn't be a walk in the park either. In my opinion, these would be funds well spent. But not sure if our elected leaders would agree. Hopefully someone behind the scenes is working on getting funds from the Biden Infrastructure plan for something like this though.
