Union Pacific's famed Big Boy No. 4014, the world's largest operating steam locomotive, journeyed from coast-to-coast, celebrating America's 250th anniversary. Starting in the spring with a stop at the Central Pacific's Milepost Zero in Sacramento, the Big Boy made extended stops in Ogden, Omaha, West Chicago, Buffalo and Scranton before celebrating Independence Day in Philadelphia.  On Big Boy's return trip to Cheyenne, the Big Boy made additional extended stops in Altoona, Pennsylvania; Fostoria, Ohio and St. Louis, Missouri.

Keep Safety Top of Mind

  • Stay back at least 25 feet from all railroad tracks. This includes drones.
  • Railroad tracks, trestles, yards and right of way are private property - do not trespass.
  • Never assume tracks are abandoned or inactive - ALWAYS expect a train.
  • Be a safe and considerate driver - do not pace the train.
  • Be Aware of the Environment: While we strive to provide access to all guests, Big Boy is positioned in a working rail environment with uneven walking surfaces that may create difficulty for accessibility.
