The first sure sign of the approaching Big Boy No. 4014 steam locomotive was the vintage horn.

“You can hear it from miles away,” Alan Nash said. “Those old steam horns have a unique tone. They’re not like what we hear on regular trains, that’s for sure. It’s got a deep roar.”

Then the ground began to rumble with increasing intensity as the locomotive approached a tunnel under the Albin-La Grange Rd 162 where a crowd of enthusiasts had gathered to witness Big Boy No. 4014 emerge from the other side.

The engineer blasted the horn a few more times for the cheering crowd as Nash, a train engineer himself, snapped photos from just a few yards away.

“You could feel the weight and the mass of it as it was going by,” Nash said. “It’s just very impressive.”

No. 4014 first took to the rails in 1941, one of five Big Boys in the Union Pacific Railroad fleet, according to the company. It mostly pulled cars between Ogden, Utah and Cheyenne before being retired in 1961 when railroads were finalizing their switch to diesel engines. Restoration of the Big Boy was completed in 2019. Since, Union Pacific has fired it up for an occasional celebratory run, attracting train enthusiasts who travel hundreds of miles to catch a glimpse of it in action.

“There’s people that are just flat out rail fans,” Nash said. “They’re crazy about it.”

On this run on June 7, Big Boy No. 4014 departed Cheyenne, chugged through Egbert then north to Albin and headed east to make its way to North Platte, Nebraska.

It was the first time Nash had the opportunity to witness the iconic piece of American engineering and Wyoming railroad history in action, he said. Nash runs Union Pacific coal trains between the Black Thunder mine in the southern Powder River Basin to just across the border in Nebraska.

Accustomed to the modern technology of today’s train engines, Nash has a special appreciation for the ingenuity behind the old Big Boys and the labor they required from his predecessors.

“To know that they did all that and they manufactured those things without all the technology that we have today is amazing.”

WyoFile's goal is to provide readers with information and ideas that foster constructive conversations about the issues and opportunities our communities face. One small piece of how we do that is by offering a space below each story for readers to share perspectives, experiences and insights. For this to work, we need your help.

What we're looking for: 

  • Your real name — first and last. 
  • Direct responses to the article. Tell us how your experience relates to the story.
  • The truth. Share factual information that adds context to the reporting.
  • Thoughtful answers to questions raised by the reporting or other commenters.
  • Tips that could advance our reporting on the topic.
  • No more than three comments per story, including replies. 

What we block from our comments section, when we see it:

  • Pseudonyms. WyoFile stands behind everything we publish, and we expect commenters to do the same by using their real name.
  • Comments that are not directly relevant to the article. 
  • Demonstrably false claims, what-about-isms, references to debunked lines of rhetoric, professional political talking points or links to sites trafficking in misinformation.
  • Personal attacks, profanity, discriminatory language or threats.
  • Arguments with other commenters.

Other important things to know: 

  • Appearing in WyoFile’s comments section is a privilege, not a right or entitlement. 
  • We’re a small team and our first priority is reporting. Depending on what’s going on, comments may be moderated 24 to 48 hours from when they’re submitted — or even later. If you comment in the evening or on the weekend, please be patient. We’ll get to it when we’re back in the office.
  • We’re not interested in managing squeaky wheels, and even if we wanted to, we don't have time to address every single commenter’s grievance. 
  • Try as we might, we will make mistakes. We’ll fail to catch aliases, mistakenly allow folks to exceed the comment limit and occasionally miss false statements. If that’s going to upset you, it’s probably best to just stick with our journalism and avoid the comments section.
  • We don’t mediate disputes between commenters. If you have concerns about another commenter, please don’t bring them to us.

The bottom line:

If you repeatedly push the boundaries, make unreasonable demands, get caught lying or generally cause trouble, we will stop approving your comments — maybe forever. Such moderation decisions are not negotiable or subject to explanation. If civil and constructive conversation is not your goal, then our comments section is not for you.

  1. Love these old guys! Each time they announce that one of them is going to “tour” I pull up the Union Pacific schedule on the internet and plan my time to see them. Even sitting still, they are awesome! Out on the track they are magnificient. Everyone should experience seeing these marvels if they can!
