No? Okay, good, let's design a train station.
That must be what happened when they did the last redesign of Union Station. It isn't just the increase in ridership, either. The entrance gate waiting areas and the sometimes multiple ticket checks are pointless. If making sure people are getting on the right train is the point, have much better signage (this is a complaint that could be made of about every train station I've ever been to). But, really, it isn't as if the trains go to too many places. If you're so concerned with people getting on the wrong train, just cut them some slack if they do.
