In another historic first, Union Pacific’s Big Boy No. 4014 will take to the rails this November for a limited holiday tour in support of the Make-A-Wish Foundation, with the world’s largest operating steam locomotive set to be on display Nov. 21 in the Denver, Colorado, area.

This will be Big Boy’s first-ever holiday tour and comes several months after the beloved 1941-era steam locomotive completed its historic coast-to-coast tour from California to New York, culminating in Philadelphia on the Fourth of July. The 14-state journey celebrating America’s 250th anniversary attracted millions of viewers.

The public is being offered a rare chance to purchase tickets for the holiday tour and ride in vintage passenger cars pulled by Big Boy as it travels from Cheyenne, Wyoming, to Denver. The trip will support the Make-A-Wish Foundation of America and include a donation from Union Pacific’s Community Ties Giving Program.

Ticket sales for patrons of the Union Pacific Railroad Museum will begin Oct. 16. Any remaining tickets will be available to the general public Oct. 19.

Big Boy will be accompanied by some very special guests from the North Pole. Santa Claus, Mrs. Claus and a few elves will be at the Denver stop, delighting children with limited edition gifts.

More details on the holiday tour will be available in the coming weeks.

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.
