If I have 3 air tanks (x2 5 gallon and x1 8.5 gallon) daisy chained together with one of the 5 gal tanks on my roof near the majority of the train horns, is there going to be any kind of delay with the other 13.5 gallons of air getting into the main tank on my roof ? (like there’d be if you installed your horns too far away from the air supply).
-
Would the airline to the main 5 gal tank on the roof need to be bigger than 1/2" in which case?
-
Should I have all the compressors connected to one tank or evenly distributed, or doesn’t it matter?
-
If my top psi horns run at 200psi, then does the safety/blowoff valve need to be rated at 200psi or does it need to be slightly higher?
-
Would a ball valve make a good manual train valve?
-
Do horns (smaller ones obviously) sound any good mounted under the bonnet/hood?
-
If the diaphragm end of a horn was mounted partly inside the car, then would it be necessary to wrap it in something sound insulating, or does all the volume only go in one direction until it exits the horn aperture?
1- as long as the line between the tanks is same size as whatever goes to the horns, your fine
2-no; 1/2" is fine
3-doesn’t matter
4- HIGHER otherwise it will blow when it isnt supposed to
5- not really, as it isnt designed for so much use, and it doesnt have a spring return
6) usually not, plus they get tons of poop in them, especially during/after winter
7) a good amount of noise will come from the back of the horn, even though it’s covered due to the vibration. Whatever you end up doing, don’t block the air holes on the back of the housing, because otherwise it won’t work.
There’s always some airflow restriction in pipes and airline but probably not enough that you’ll notice.
