I may have posted this before, I am getting old and can't remember.... we are all familiar with the Federal Q on fire apparatus and know how they sound. I have been trying to figure this out for awhile, there are some versions of the Q that has a slower wind up and don't peak as high... looking at them they look the same as a normal Federal Q but there is something different with them. Anyone have a clue as to what was different? I always thought this was the A series of Federal Q but I can't seem to find a reference to them. If you watch the video below there are 3 pieces of apparatus making this corner, Engine 2-1 from Waynesboro is first.. it has a normal Q, Engine 4-2 from Blue Ridge Summit is next and it also has a normal Q, the third engine is from the Leitersburg Fire Department in Washington County, MD and it has the Q I am talking about. Any thoughts my fellow countrymen?
