Train Horn FAQ

Yes. The Conductor’s Special 127H kit includes Shocker XL horns, a 1.5‑gallon air tank, compressor, pressure switch, hoses and fittings, wiring, and mounting hardware. It’s a complete system to install on your truck.

Honk time depends on tank size. A 1.5‑gallon setup typically provides around 3 seconds per continuous blast. Larger tanks provide more time: 2‑gallon ~3–5 seconds, 3‑gallon ~7–9 seconds, 5‑gallon ~10–12 seconds.

The 127H system operates at 120 PSI and automatically restarts around 90 PSI via the pressure switch. The compressor doesn’t set the cut‑off; the pressure switch does.

Shocker XL is one horn with four bells. The horns include a stainless electric air valve, hoses and fittings, and mounting hardware. In the 127H kit, they’re paired with the tank, compressor, and wiring.

Yes. Beyond powering the horns, the onboard air can inflate tires and handle light air tool tasks for added utility.
