Baltimore City Fire Department

[firepost]

It's been a while since the Ambulance designations have been brought up. I was wondering what the difference between the 40, 50 and 60 series ambulance or "Med" units are. I notice that Baltimore City currently runs with Med units 41 through 46, Med unit 51 and Med units 61 through 66. Where are they located and why are there six 40 series and six 60 series Med units but only one 50 series Med unit.

Are there still Paramedic Engines on the Baltimore city fire department. What Engines are the Paramedic Engines?

Thanks!
