train horns

hey guys, iv been thinking about installing a set of train horns in my truck sense its already got air.
so question is anyone here run them of have experience with train horns? i hate to spend 300 bucks on a set without knowing more. all info is welcome and links would be tits!
thanks guys

Am running a set of train horns on the daughters truck. Work nicely running off a spare port on the tank. Works great at 145psi but not sure I would try them at 200psi.

ive got a set of kelinn train horns. i think the 220s. they are loud as hell with 200psi. best results with any horns is to have them mounted facing down towards the ground. the sound bouncing off the ground will double to loudness of any horn you get. i think i paid nearly $200 on ebay for them brand new in box.

my comps shut off 145 so thats what id run horns at. do you have a link to what horns have? how loud are they?
thanks

anyone try either of these?

Have no idea what horns I have. There are 3 horns clustered together and they are pointed at a 45 degree angle at the ground. And yes, they are loud as he!!

edit - this is them....

i've got dual kleinn train horns mounted in between my radiator and my lower valence on my Ranger. i run them at 200 psi just like the rest of my air system and they are crazy loud.

i just ordered this set!

i have the shocker xl on my dailer running at 150psi and have ran them at 200psi for a long time and they are loud as hell. i have had the outlaw before and they are loud as well but the shocker is much louder. i would recomend them. i love them and will eventually put another set on my mazda
