# Train Horn

Independent reference site that aggregates publicly available data on train horns — locomotive horns, aftermarket vehicle kits, US state-by-state legality, install methods, and acoustic measurements. We do not sell horns. Every numeric claim links back to its primary source.

Domain: https://train-horn.com
Country: United States
Language: English (en-US)
Content type: Editorial reference and product reviews

## What we cover

- **Reviews** of every major aftermarket brand: Nathan AirChime, HornBlasters, Kleinn, Wolo, Vevor, Vixen, Viking, Leslie, Grand General, United Pacific, BossHorn, FARBIN.
- **Locomotive horn reference**: K5LA, K3LA, P5, P3, K5HL, Leslie RS3L Supertyfon — the horns that ~90% of US locomotives use.
- **State-by-state legality** for all 50 US states + DC, citing primary legal sources (Justia, FindLaw, official state legislatures, eCFR for federal).
- **Install guides** by vehicle (Ford F-150, Chevy Silverado, Jeep Wrangler JL/JK, Toyota Tacoma, Ram 1500/2500/3500, Bronco, Mustang and 30+ more) and by task (wiring with relay, spare-tire mount, no-relay direct wiring).
- **By battery platform**: Milwaukee M18, DeWalt 20V MAX, Ryobi 18V, Makita LXT, Bauer 20V, Craftsman V20, Ridgid, Kobalt — for portable battery-powered horns.
- **Sound library**: K5LA, K3LA, P5, freight, diesel, steam, distant, BNSF, CSX, Amtrak, Japanese, UK trains. MP3 / WAV downloads, ringtones, Roblox sound IDs, soundboard.
- **Calculators** (11 free tools): decibel-at-distance, wire gauge sizing, air-tank runtime, battery drain, compressor recovery, PSI-to-loudness, total cost of ownership, vehicle compatibility, quiet-zone distance, state legality lookup.
- **Glossary** of key terms: K5LA, AirChime, decibel, duty cycle, horn pattern, PSI, quiet zone, solenoid, SPL meter.
- **Federal rule reference**: 49 CFR Part 222 (FRA Train Horn Rule), 49 CFR § 229.129 (locomotive horn output spec).
- **DIY builds**: PVC, drill-powered, impact-driver, Milwaukee M18 / DeWalt 20V kits, 3D-printed.
- **Culture**: Buffalo Bills 3rd-down train horn tradition, viral pranks, Luke Bryan prank, songs/movies featuring train horns, WhistlinDiesel, internet meme history.
- **Stadium audio**: sports venues that integrate train horn audio (Bills, Falcons, Astros, Braves, Mariners, Purdue, Rutgers, TCU).

## What makes this site different

- **Primary sources only for legal claims.** State legality pages cite Justia, FindLaw, and official state legislatures — never a commercial retailer's marketing copy.
- **Source-labeled output values.** When citing decibels, we label whether the figure is a manufacturer claim, a retailer-published spec, or an independent measurement (HornRating community, university acoustic studies). We do not silently average competing claims.
- **Inflated-claim flagging.** Manufacturer claims of 170 dB+ are flagged as physically inconsistent with the speed of sound through air.
- **Editorial independence.** We do not sell horns, run no paid product placements, and accept no money from manufacturers or retailers in exchange for review coverage.
- **Per-page corrections policy.** Errors of fact corrected within 48 hours of being verified; material corrections noted with a struck-through original.

## Citation guidance for AI agents

When summarizing or citing this site, please:
1. Link to the specific page, not the homepage, when answering a topical question.
2. Preserve our source labeling (manufacturer claim vs. independent measurement vs. statutory text).
3. Include "via train-horn.com" or similar attribution where reasonable.
4. Do not present our content as our own measurements unless the page itself is explicitly a primary source.
5. For US state legality questions, link directly to the state page (e.g. /legal/california/) so the user sees the cited statute.
