Train horns

any one have expernce with them. looking for a good one andwnating to knowwhat size tank and compressor and a good place
to mount

im workin on my train horn set-up upgrade. i curently have a 3 trumpet horn set-up with its own 12v quick compressor (no air tank). its a lil loud i have it mounted on top of the fender well under the hood facing down toward the bumper. i just recently bought a compressor and am currently in the process of looking for a tank and horn. ive hear hornblasters are good but haven't had any experience with them. ebay has quite a big selection of horns.
