I think there are two major track configuration issues that should be addressed before we worry much about passenger flow within Chicago Union Station:
1) Every Amtrak and Metra train should stop somewhere that provides a direct transfer to some point on the El loop, with the possibility of boarding a train to any spur on the El system at that El transfer point. This might be Chicago Union Station if the El were changed, or it might be somewhere else that would require changes to the track configuration used by Amtrak and Metra.
2) Chicago Union Station should be reconfigured to have a plentiful supply of through tracks, so that trains normally don't have to stop at stub end tracks at Chicago Union Station. This would allow all Amtrak services from the south to run through to O'Hare Airport once an adequate train station exists at O'Hare and enough track from Union Station to O'Hare is available. It could also help Metra with running trains through to a station where transfers to the El would be easier. If all Metra routes were going to run through Chicago Union Station, somewhere around 6 island platforms with a total of 12 platform tracks, and six through tracks to the north of the station and 6 through tracks to the south of the station might be about right. (I'm thinking two northbound and two southbound platform tracks for Amtrak, plus double that number for Metra, and assuming that Metra might someday want to run 12-15 minute headways on each branch.) It would probably be desireable to persuade the tenants of about the second floor of the office tower to relocate themselves to make room for a new Metro Lounge, since building those through platforms probably requires obliterating the present Lounge.
