Daniel Lee took his 2015 Ford F350 to the next level with a HornBlasters Conductor’s Special 544 Nightmare Edition Train Horn Kit and an additional set of Shocker XL Train Horns for even more commanding sound. HornBlasters documents the 544 Nightmare Edition as HK-S4-544K: Shocker XL bells plus a 5-gallon eight-port tank and the HB-1NM compressor.
The Conductor’s Special 544 Nightmare Edition Train Horn Kit was mounted underneath the truck, giving Daniel a clean installation while maximizing available space. By pairing the 544K kit with the extra Shocker XL horns, this F350 delivers an unmistakable train horn blast that’s impossible to ignore—more bells, more chord presence, and the air reserve to back it up on a Super Duty platform.
Whether cruising the highway, attending truck meets, or showing off at events, this setup gives Daniel’s Super Duty the powerful sound and presence that HornBlasters is known for. The combination of onboard air, genuine train horn performance, and the added Shocker XL horns makes this one serious truck horn build. HornBlasters lists 150 PSI operation with 110 PSI restart, roughly 10–12 seconds of honk time from the 5-gallon tank alone, and about 2 minutes to recover from 110–150 PSI under published test conditions—plan for higher air demand when dual Shocker XL sets share the same tank.
