I have a set of Union Pacifics on my scsb silverado. I didn't go the compressor route and run them off a nitrogen tank. They are pretty much awesome, I have had them for at least 2 years. I also have mine on a switch incase I need a stock horn. Nitrogen is cool because I have my regulator spun up to about 300psi
but on the downfall, I have to get it filled up prob 3 times a year. I also have my alarm hooked to the train horn so if anyone wants my goodies, they better be faster than I can load my .45.
