Only recently found this forum just by checking out more train horn stuff online.
My horn isn’t technically a ‘train’ horn, but it IS a a horn from the Disneyland Monorail, which I think qualifies.
I installed a Grover 1054 & 1055 combo, with a Viair 150 PSI compressor & tank combo.
I just recently installed it about 6 months ago, and love it! It’s no K5LA as far as loudness, but it’s definitely no slouch when I wanna get someone’s attention!
Anyway, just here to introduce myself, glad to be here, and I’ll post some pics and videos in a more appropriate area. 
Welcome to the forum we want pics.
Cool stuff - I checked out your pics and vids.
Welcome, we like all horns.

Thanks guys! Glad to share something a little different than you’re used to.
cool! I have a Grover 1045 and 1042 on my truck, 200psi Regulated down to 135 for the truck horns. Welcome to the forum!
