Departments in DuPage County that operate on the DuComm north channel (154.1750) are instigating a new numbering system for stations and apparatus. Some of those changes are outlined below;

West Chicago FPD
Sta 2 = 5    Eng 5 Amb 5
Sta 1 = 6    Tower 6, Tnk 6, Sqd 6 Battalion 6
Sta 3 = 7    Eng 6 Amb 6  
Sta 4 = 8    Eng 8? (it’s the crash rig)
Carol Stream FPD
Sta 3 = 27    Sqd 27, 27a Amb 27
Sta 1 = 28    Tower 28, Amb 28 Bn 28
Sta 2 = 29    Eng 29 Amb 29
Winfield FPD
Sta 1 = 31    Eng 31 Tnk 31Amb 31
Sta 2 = 32    Eng 32

John Tulipano tells us that
these changes are part of a larger program that is instituting combined training, SOP’s and SOG’s in several towns and FPDs. There has been on-going combined training and standardized operating procedures since at least last summer. As an example, the TL in West Chicago and the TL in Carol Stream have the same seating assignments and operating procedures on the fireground.
