Got some tidbits to add.
Byron Exelon had a system of Penetrators and Banshees as mentioned, but I do recall seeing a Thunderbolt in Stillman Valley and I believe an Allertronic at the Byron Dragway, both of which are gone. I've been mapping out their sirens now and have found T-128s and T-135 AC/DCs, but there are still actually many Penetrators left (they make up about half of the system still, but is unknown whether they're single or dual tone.) What kind of surprised me though is that I haven't found a single P-50 or T-135 AC yet, which is weird since most other Exelon systems in Illinois do.
Clinton's system, like most other Exelon systems, is comprised of T-128s, T-135s, P-10/P-15s, and P-50/T-135 ACs. I am not familiar with their old system, though it appears they had a lot of Penetrators as well.
La Salle's system has T-128s, P-15s, and P-50s mainly with a few T-135 AC/DCs here and there. The old system was mainly Thunderbolt 1000's, Penetrators, and one or two Whelen 3016s.
Dresden's system is pretty much the same as Clinton's system, except in the past it was littered with Thunderbolts, plus some P-15s, STH-10s, and 2T22s. As a matter of fact, I used to live only a couple blocks from a Dresden 2T22 and that's how my interest of sirens started. Now the closest sirens to me are an Excel T-128 and an inactive STH-10 (former fire siren, not Dresden.)
Hope this helps.

Sirens, they're loud!
