That is something I can investigate. From my observations, they are there virtually every time I'm in the south concourse.
Shifting gears, this article was cited in another thread. In brief, Amtrak is publicly accusing NS of delaying trains on Twitter. NS is responding that Amtrak's equipment failures are creating the initial delays, leading to cascading further delays that result from a train getting out of it's scheduled slot. I have had the same experience on NS, CSX, and BNSF. BNSF is generally accepted as the best time keeper for Amtrak, but still 3/4 can be further delayed around Fort Madison and KC if it's out of slot.

That's germaine here because it's clear the freight hosts are frustrated with Amtrak's self-inflicted delay enough that they're threatening legal action. The initial terminal delays at Chicago are certainly included on that list. The NS main east of Chicago is one of the busiest in the United States, and well known for delays. This is why I'm so vehement about this subject. It's one that all the parties are talking about. It's serious. And it's causing problems for passengers.
When neither Amtrak, NS, nor passengers are happy, isn't it time to find a solution?
