IMHO, this has much to do with the layout of tracks and stations in general in the US. In the case of Union Station in Chicago, the current track layout hasn't been overhauled in thirty years (but is the next stage of the overall renovation project). While I have no clue as to why it is laid out as it is today, it certainly leaves much to be desired as to usability and clarity.Still a mystery to me why boarding a train in the US has to be such a complicated process. Rest of the world - you display the platform/track, people get on.
But let's contrast that to airport terminals in the past forty years or so. Many an airline traveler had horror stories of this airport or that airport being a confusing mess and hard to navigate for the casual traveler. Nowadays, there are airports that actually get kudos for being traveler friendly. Part of that has to do with the interior design concept known as 'wayfinding'. Industrial designers are now employed in renovation projects to integrate designs with the manner in which people actually use the facilities. [Fun fact: given a central common entrance to a building, most people will automatically gravitate towards the right. Most redesigns of buildings use that behavioral anomaly to locate important and/or commonly used services. This is why information kiosks may not be directly ahead when entering a public facility.]
