The Toledo FD station and apparatus page on their site has not been updated since they realigned equipment this past summer. Station 3 now houses an Engine and a Rescue unit.
Based on Pro96Com activity logs of Lucas County system data, Station 3 acknowleged alerts to their primary station receiver at least 358 times (and that includes three daily alerts that are test alerts). I have also logged at least 331 transmissions from Engine 3's mobile radio and at least 2,001 transmissions from Rescue 3's mobile radio.
Based on looking through all the transmission data for Engine companies, it looks like Engine 7 is the most active and Engine 24 is the least active . . .
