CHEYENNE, Wyo. — Some 27 whistle stops are planned along with four public display days on the western tour of Union Pacific Big Boy No. 4014, which begins March 29 with departure from Cheyenne.

UP today announced the full schedule for the western trip, the first part of a planned coast-to-coast journey, in an email today (Feb. 24) to its Steam Club members.

No excursions are planned as part of the trip that concludes on April 24 in Cheyenne. The railroad will be auctioning off two cab rides in the locomotive on April 17 in Utah, with proceeds going to the Union Pacific Railroad Museum in Council Bluffs, Iowa. The auction begins March 2 and ends March 19; information and registration is available here.

The whistle stops are generally 15 to 30 minutes long. They are planned in these communities; details on the specific locations are available on the full schedule linked above.

Union Pacific 4-8-8-4 Big Boy No. 4014 will run from Cheyenne, Wyo., to California and return as part of its 2026 outings. UP
