Same down in my neck of the world. Montgomery and Chester Counties use "plain language" as well. The 911 service I work for is Station 87 and has, for example, Ambulances 87-1 through 87-6 (can be called MICU if ALS-staffed), Medic 87-1 and 87-2, and Utility 87. (I'll post some pics in better weather). Our associated fire company has Chief 47, Deputy 47, etc,...pumpers are simply ENGINE XX-1, -2, etc,.. (ENGINE XX-5 or -6 indicate pumper tankers, a throwback to our old system), ladders are LADDER XX, TOWER XX or QUINT XX, rescues are RESCUE XX and so on. Lieutenants, engineers and specialty officers are identified by a two-digit number after the station (XX-10 is the chief engineer, XX-20 = ambulance captain, XX-30 = fire police captain, etc,...). I'm going to throw this out there: will this be a mandatory change? I know several coal country counties in PA changed their systems when they went to a county-wide 911 system and in both counties, quite a few departments simply refused to change and continue to maintain their "old" numbers.
