2026 · 250th Anniversary Tour

Coast to coast under steam.

Big Boy 4014 — the largest operating steam locomotive in the world — is rolling across the United States to mark America’s 250th. This is an unofficial fan tracker for the tour: the schedule, the route, where the train is meant to be today, and the history behind every stop.
