Amtrak WiFi is a complimentary onboard internet service offered to passengers on many trains. It is primarily designed for light browsing activities rather than high-bandwidth tasks. The service relies on cellular signals from towers located along the tracks. As the train moves, the WiFi signal hops from tower to tower—similar to how your mobile phone works while traveling. https://amtraktrainstations.com/blog/does-amtrak-have-wifi/
