Adirondack cell service FAQ
Does the Adirondack have cell service?
For most of the trip, yes. Inside the train, solid coverage (the FCC's in-vehicle model) reaches 73% for AT&T, 60% for Verizon, 34% for T-Mobile of the 381-mile route from Montreal, QC to New York, NY. Much of the rest is spotty rather than dead: AT&T has some signal on 92%, Verizon has some signal on 96%, T-Mobile has some signal on 80%.
Which carrier is best on the Adirondack?
AT&T has the most modeled on-train coverage (73%), with 5G on 53% of the route. Verizon covers 60% and T-Mobile covers 34%.
Where is the longest dead zone on the Adirondack?
AT&T: about 8 miles between Ticonderoga and Whitehall. Verizon: about 4 miles between Ticonderoga and Whitehall. T-Mobile: about 30 miles between Port Henry and Ticonderoga.
Does Amtrak Wi-Fi work on the Adirondack?
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.
