What Is Railroad Scanning?

Railroad scanning lets you listen to dispatcher, engineer, and yard chatter on the public 160 MHz railroad band. That means you can predict train movements, plan photo spots, and enjoy the soundtrack of the rails.

It’s 100 % legal to listen—as long as you never transmit. Most conversations are brief, use simple codes, and give you a front‑row seat to railroad operations.

AAR Channel List & Download

Below is the current Association of American Railroads (AAR) master list. Each channel number maps to a specific 0.015 MHz‑spaced frequency.

Complete U.S. Railroad Scanner Frequencies (AAR 001-097)

Tip ▸ Most railroad conversations are simplex—transmit & receive on the same channel—so simply dial the channel’s frequency to listen. Channels 7-97 are the industry work-horses across the U.S.

Best Rail Scanners for 2025

Choosing a scanner is easier when you know what matters: analog FM, railroad service search, and alpha tags.

We HIGHLY recommend the Uniden SR30C if you ONLY want to hear rail. If you want ot hear rail AND more, the Uniden SDS100 is our recommendation.

Want it pre‑programmed? We’ll ship it ready to scan.

Programming Your Scanner

Even the simplest scanner can feel intimidating on day one. Follow these five bite‑sized steps and you’ll catch your first dispatcher call in under ten minutes.

1. Reset the scanner so you start clean.
2. Enter the primary road channel for your subdivision.
3. Add the dispatcher and defect detector channels.
4. Label each channel (if your model supports alpha tags).
5. Store the bank and start scanning.

Digital vs. Analog

Most rail traffic is still narrowband analog FM. But several Class I railroads are testing NXDN digital on yard and maintenance channels.

If you railfan in BNSF or CSX territory, a digital‑capable scanner like the SDS100 keeps you future‑proof. Positive Train Control (PTC) beacons also ride the 220 MHz band, but they’re data bursts you can’t decode with consumer gear.

Narrowbanding & Future Changes

The AAR has proposed stepping down from 15 kHz to 6.25 kHz channel spacing by 2027. Nothing is locked in yet, but new radios (and the BCD160DN) already support the tighter spacing.

For now stick with the published list, but expect new “splinter” channels to appear in your scanner’s service search soon.

State‑By‑State Scanner Laws

It’s legal to own and use a railroad scanner in every U.S. state. But a few states restrict mobile use without a ham license.

Troubleshooting Reception

Nothing but static? Run down this checklist:

• Wrong Channel – verify the subdivision is correct.
• CTCSS/DCS Enabled – turn off tone squelch.
• Attenuator On – disable it for weak signals.
• Poor Antenna – swap to a 1/4‑wave whip tuned for 160 MHz.
• Too Far Away? – move within 5 miles of mainline.

Pro Tips for Railfanning Safely

Stand at least 25 feet from the nearest rail. Carry ear protection around horn‑happy engineers. Monitor defect detector channels for train length and speed intel. Log channels in a notebook — over time you’ll predict meets like a pro.
