Run-by's of my Custom Built Acela Style Split Hybrid K5LA

Here it is, after years of planning, gathering materials and sourcing parts, I have finally built myself the ultimate Acela style, split hybrid K5LA! As some may not know, the Acela power cars came equipped with a hybrid K5LA, however this one is a little different. The approach to attach a monstrous K5LA to these electrified high speed commuter trains was going to be somewhat of a challenge. Due to limited space on the roof, the horn had to be split into two sections. Basically a K3LA and a K-3,5. Together, these horns play what we know as the "hybrid" K5LA. I'm not sure as to how these ended up with a straight 3 bell instead of a 3A, but I really appreciate that difference. To me, it sets the Acela trains apart from anything else in Amtrak's fleet. I remember watching Amtrak's Acela Express videos on CZcams when I was just a kid, amazed at how great those horns sounded. Watching each Acela video gave me more and more inspiration to build this. And now, I'm glad that I have actually built one.
Future modifications I would make would consist of constructing a 2-stage solenoid, as I'm just using my standard Graham White 353 valve (which honestly does the job just fine, but I'm going for authenticity). And another modification I would make is possibly constructing a proper mount, instead of shelving made of particle board. I'm thinking along the lines of a CNC machined baseboard.
In the very beginning of the video, I've attached a photo of the actual Acela hybrid K5 form one of their power cars I found online. The other photos is this very horn you hear in the video, accurately re-creating Acela's signature sound.
Sit back, relax and enjoy these awesome sounds!
Thanks for Watching!

I love the sound of those hybrid K5LA horns. I live in southwestern CT near the part of Amtrak's NYC to Boston line and I've heard these horns several times.

10x better than the clown car french crap on the Acela's not FRA approved "replacement" One of my favorite horns.

Nice B major 7th right there!

[@WeenyBeanyHere]

Had no idea the Acela had a split manifold
Very cool setup!

[@NorthAtlanticRails]

Accurate. How do I get or make one?

[@Mcnibbus]

Where can I make or get one of these god damn
