Vermonter cell service FAQ
Does the Vermonter have cell service?
For most of the trip, yes. Inside the train, solid coverage (the FCC's in-vehicle model) reaches 88% for AT&T, 82% for Verizon, 73% for T-Mobile of the 601-mile route from St Albans, VT to Washington, DC. Much of the rest is spotty rather than dead: AT&T has some signal on 95%, Verizon has some signal on 98%, T-Mobile has some signal on 93%.
Which carrier is best on the Vermonter?
AT&T has the most modeled on-train coverage (88%), with 5G on 61% of the route. Verizon covers 82% and T-Mobile covers 73%.
Where is the longest dead zone on the Vermonter?
AT&T: about 17 miles between Montpelier and Randolph. Verizon: about 9 miles between Montpelier and Randolph. T-Mobile: about 16 miles between Montpelier and Randolph.
Does Amtrak Wi-Fi work on the Vermonter?
Amtrak Wi-Fi relies on cellular networks, so it generally weakens or drops in the same places your phone does. Expect it to be unreliable through the dead zones shown on this map.
How accurate is this coverage map?
It reflects carrier-reported modeled coverage published by the FCC (data as of Dec 31, 2025). It is not an onboard measurement. BarTrakr shows the FCC's in-vehicle model by default; the outdoor model is available with the Outdoor switch.
Can I use BarTrakr on the train without signal?
Yes. Tap “Save for offline” before you board. The route, coverage data and map background up to zoom 10 are stored on your device, and live tracking uses your phone's GPS, which works without cell service.
About this data
- Coverage: FCC Broadband Data Collection mobile coverage for Verizon, AT&T, T-Mobile, release D25 (as of Dec 31, 2025, published Oct 13, 2026).
- Route: U.S. DOT / BTS National Transportation Atlas Database, Amtrak Routes. Stations and stop order: Amtrak GTFS.
- On the train: colored where the FCC in-vehicle model shows coverage; amber (spotty) where only the outdoor model does; red where neither does.
- Stretches shorter than a quarter mile are merged into their neighbors; at train speed they last only seconds.
