Buffalo Grove Train Horn Schedule
Metra's Milwaukee District North line and Canadian National freight pass through Buffalo Grove. FRA grade-crossing horn rule applies to every public crossing. Established quiet-zone segments silence the horn at qualified crossings.

Informational only — not legal advice. Quiet zone status varies by individual crossing and changes over time. Verify with the Village of Buffalo Grove and the FRA Quiet Zone Database before relying on this content.
Federal framework — FRA train horn rule
Under 49 CFR § 222, every locomotive must sound the standard pattern (• • — •) at every public highway-rail at-grade crossing, starting 15–20 seconds before reaching the crossing. The horn must produce 96–110 dB measured at 100 ft. This applies in Buffalo Grove and every US municipality.
Cities can establish Quiet Zones (silencing the horn) only after FRA-mandated safety improvements: medians, four-quadrant gates, wayside horns, or other supplemental safety measures (SSMs / ASMs). See the FRA Quiet Zone process page.
Buffalo Grove rail context
- Metra Milwaukee District North line — passenger commuter service from Chicago Union Station north through Buffalo Grove to Fox Lake
- Canadian National Railway — freight operations on shared trackage
- Wisconsin Central (now CN) — historic operator on this corridor
- Multiple at-grade public crossings throughout the village
The Village of Buffalo Grove has historically pursued quiet-zone establishment for portions of the corridor. Specific crossings and effective dates require verification via the FRA Quiet Zone Database.
How to verify the current quiet-zone status
- FRA Quiet Zone Database — search by city or county for active quiet zones and their effective dates
- Village of Buffalo Grove official site — local quiet zone communications
- Metra — official site (Milwaukee District North line operator)
What "schedule" means in this context
There's no fixed "horn schedule" — Metra trains run on published timetables, but the horn pattern is sounded as each train approaches each crossing. Approximate horn frequency at any specific Buffalo Grove crossing matches the Metra Milwaukee North timetable (typically 30–60 trains daily on weekdays at peak service).
Outside scheduled passenger service, freight trains pass at irregular times — typically overnight to avoid passenger conflicts.
Vehicle train horn rules — Illinois state law
Vehicle horn rules in Buffalo Grove follow Illinois state law, not local ordinance. Under the Illinois Vehicle Code:
- Every vehicle must have a horn capable of producing an audible warning
- Horns may only be sounded as a warning of an immediate hazard, not as a noise display
- Sirens, whistles, and bells are restricted to authorized emergency vehicles
