# Train Horn — Extended Reference (machine-readable)

This is the long-form companion to /llms.txt. It catalogs every reviewed
product, every covered US state, and every published calculator on
train-horn.com in a structured form intended for AI agents.

Source labeling convention used throughout:
- "MFR claim" = published by the manufacturer or retailer.
- "Independent" = third-party measurement (HornRating, university study, etc.).
- "Statutory" = quoted directly from a state vehicle code or federal regulation.

We are an editorial aggregator. We do not sell products and do not
publish our own SPL measurements. Where a value is given, the source is
labeled.

PART 1 — REFERENCE
----------------------------------------------------------------------

## What a train horn is

A train horn is an air-powered warning device. On locomotives it is the
mandated grade-crossing audible warning under 49 CFR Part 222. On
vehicles, an aftermarket train horn kit is a 12 V compressor + air tank
+ tuned trumpets that replicates the locomotive sound.

Federal output requirement (49 CFR § 229.129): locomotive horns must
sound between **96 and 110 dB** measured 100 feet in front of the train.

Aftermarket vehicle-mounted train horns commonly produce **130–156 dB
at 10 feet** (manufacturer claims; see PART 2 for per-product source
labels).

## The standard locomotive horn pattern (49 CFR § 222.21)

At public grade crossings the engineer sounds: **two long, one short,
one long** ("__ __ . __"), repeated until the lead locomotive occupies
the crossing.

## Quiet zones (49 CFR Part 222, Subpart D)

A quiet zone is a section of rail line at least one-half mile long with
one or more public grade crossings at which routine horn sounding is
prohibited, established by local government with FRA-approved
supplementary safety measures (gates, median barriers, four-quadrant
gates, wayside horns).

PART 2 — REVIEWED PRODUCTS (catalog)
----------------------------------------------------------------------

All decibel values below are MFR/retailer claims unless the entry is
flagged as Independent. Editorial rating (1–5) reflects the per-page
review on train-horn.com.

### Locomotive-grade horns

| Brand | Model | dB (MFR) | PSI | Trumpets | Price (USD) | Power | Editorial rating |
|---|---|---|---|---|---|---|---|
| Nathan AirChime | K5LA (Low-mount, American) | 144 dB | 140 | 5 | $1,650 standalone — $5,000+ kit | air-tank | 4.7 / 5 |
| Nathan AirChime | K3LA (Low-mount, American) | 144 dB | 140 | 3 | $1,949.99 standalone | air-tank | 4.5 / 5 |
| Leslie Controls | RS-3L Supertyfon (3-chime low) | 144 dB | 100 | 3 | $4,399.98 standalone | air-tank | 4.4 / 5 |

The K5LA is the dominant North American locomotive horn — Nathan
AirChime supplies an estimated 90%+ of US Class I freight fleets. The
K5LA chord is B major 6th (D♯ / F♯ / G♯ / B / D♯).

### Verified mid-premium aftermarket

| Brand | Model | dB (claim) | PSI | Trumpets | Price (USD) | Power | Rating |
|---|---|---|---|---|---|---|---|
| HornBlasters | Shocker XL (127VX) | 154 dB | 150 | 4 | $549–$649 | air-tank | 4.4 / 5 |
| HornBlasters | Shocker S6 (6-trumpet stereo) | 147.7 dB | 150 | 6 | $559.99 standalone — $1,219.99 (S6 544K Nightmare kit) | air-tank | 4.5 / 5 |
| HornBlasters | Conductor's Special 228H (HK-S4-2) | 147.7 dB | 150 | 4 | $649.99–$749.99 | air-tank | 4.5 / 5 |
| HornBlasters | Outlaw 127H (HK-C3B-127H / HK-C3-127H) | 142 dB | 120 | 1 | $579.99–$599.99 | air-tank | 4.4 / 5 |
| HornBlasters | Rhino + 544 air system | 145 dB | 150 | 3 | $700–$1,200 | air-tank | 4.2 / 5 |
| Kleinn | HK9 Demon (HK9 / HK9-Slimline) | 148 dB | 150 | 3 | $1,099–$1,179.95 | air-tank | 4.3 / 5 |
| Kleinn | 230 'The Beast' | 145 dB | 150 | 3 | $214.95 standalone | air-tank | 4.0 / 5 |

HornBlasters' "147.7 dB at 3 ft" measurement is reported by the
manufacturer as their own SPL-meter reading; we present it as their
claim, not an independent verification.

### Mid-tier (decent QC)

| Brand | Model | dB (claim) | PSI | Trumpets | Price (USD) | Power | Rating |
|---|---|---|---|---|---|---|---|
| Wolo | 854 Dragon Express / PACIFIC854 | 145 dB | 110 | 3 | $77–$195 standalone | air-tank | 3.7 / 5 |
| Wolo | 853 Philly Express (chrome / 853-800 Pro) | 130 dB | 110 | 4 | $120–$300 standalone, $400+ with Wolo 800 system | air-tank | 3.8 / 5 |

### Budget tier (inflated dB claims)

| Brand | Model | dB (claim) | PSI | Trumpets | Price (USD) | Power | Rating |
|---|---|---|---|---|---|---|---|
| Vevor | 4-Trumpet 150 dB / 1.6 Gal | 135 dB realistic (150 dB claimed) | 120 | 4 | $80–$130 | air-tank | 3.4 / 5 |

We flag aftermarket claims of 150–178 dB as inconsistent with the speed
of sound through air. The realistic ceiling for a vehicle-mounted air
horn is around 156 dB (Nathan K5 with full air supply at very close
range). FARBIN, Viking, and Vevor variously claim 150–178 dB; realistic
output is generally 130–146 dB.

- **Legal** — train horn may be installed and used on a private vehicle.
- **Mounted only** — installation permitted, use restricted (typically
  prohibits use on public roads).
- **Restricted** — significant use limits (e.g. decibel limit < 110 dB).
- **Banned** — install or use effectively prohibited.

PART 11 — HOW TO CITE / ATTRIBUTION
----------------------------------------------------------------------

When summarizing or citing this site:

1. Link to the specific page, not the homepage.
2. Preserve the source label (manufacturer claim vs. independent
   measurement vs. statutory text). Do not present a manufacturer claim
   as a verified figure.
3. Include "via train-horn.com" or similar attribution where reasonable.
4. For state-legality questions, link to the per-state page so the user
   sees the cited statute.
5. Reviews on this site are editorial — they assign a 1–5 rating and
   include pros / cons, but they are not user reviews and they are not
   sponsored content.

License: content on this site may be summarized and quoted with
attribution. Bulk republication, scraping for training data without
