Not sure of the timeline but the BNSF has slowly been changing them out for a while.

While at Eola yesterday traffic on my scanner indicated signal crews were working near the Naperville station replacing the signal tower just east of the station (this has been going on for a while now). I am anticipating the towers within the Eola yard limits to come down some day soon as we have seen the replacement components sitting on the ground near the yard office for some time now.

I believe they are going to replace the Eola signal bridges, not eliminate them. No word on time frame yet.
I suspect that a lot of this signal replacement is for practical reasons, instead of merely replacing signal bridges for the sake of replacing bridges. For example, the crossovers that used to be between LaGrange and Congress Park have been (apparently) eliminated or relocated further east, making that bridge east of LaGrange Road a distant signal instead of a home signal (sorry about the old terminology--it's my day off and the rulebook is put away).
I've also noticed that the new bridges are considerably taller than the old ones--I'm sure the double-stacked containers weren't scraping the old signals, but is it possible that clearances were a little too close for comfort?
What's curious to me is that the signals are being changed out, too--the old searchlight signals (with moving parts and therefore more subject to failure) are most often replaced with hooded color-light signals. Yet some of the new bridges have just-as-new searchlight signals on them. What's with that?

I don't think so, Jim.
The signals I can see head-on (LaGrange, mostly) appear to be standard incandescant lights, not LEDs. Even when you can't observe them close-up, the difference in the flashing aspects is obvious: LEDs would light up and cut off much faster than these signal lights do.
