Cadet Class 133 will be reporting to District-Chicago and Oak Brook District 15 (Tollways) as of Monday. Expect to hear new voices, or see new Radio ID's on District-Chicago talkgroups if you follow them. Oak Brook usually stays with their current ID structure but the troopers will use "Car 300-Car 318 for example" and the ID's will be their "future" cars they will be assigned. You might see 15179, but the trooper will be using radio signature Car 300 as an example.
