According to Union Pacific Railroad, the locomotive is making a rare trip to the eastern United States as part of its 2026 tour.

Big Boy is expected to enter the Pittsburgh area after 11:15 a.m. on July 11, traveling through Trafford before crossing the Monongahela River and passing through communities including Homestead, Duquesne and Pittsburgh’s South Shore.
