AT&T has the most modeled on-train coverage (94%), with 5G on 90% of the route. Verizon covers 86% and T-Mobile covers 80%.
Where is the longest dead zone on the Heartland Flyer?
AT&T: about 0 miles near Oklahoma City, OK. Verizon: about 2 miles between Pauls Valley and Ardmore. T-Mobile: about 4 miles between Pauls Valley and Ardmore.
Does Amtrak Wi-Fi work on the Heartland Flyer?
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.
