Railfanning the Big Boy

Wow, was it fun to see the Union Pacific Big Boy 1440, as it chugged though Missouri in July.

The “Big Boy” steam engines were built in the 1940s in order to haul incredibly heavy loads around (including across the Rocky Mountains) for the war effort. These engines weighed 1.2 million pounds. Eight of these crazy-huge locomotives still exist, and Union Pacific’s restored Big Boy 1440 is the only one that runs. So they take it around the country every so often for publicity purposes.

Its 2026 tour is over, but you can find tons of YouTubes showing it at various points on its journey. I decided to add my little video (belatedly) to the fray. I think I was the only person videoing it in Bonnots Mill.

Railfanning is a thing; I’ve blogged about it before. A lot of railfans seem to video every train they see. I’m not that nutty about it, but I couldn’t help myself once I realized the massive train would be crossing the little trestle that crosses the drive connecting Bonnots Mill’s Old Mill Road and Osage County Road 416.

At first, Sue and I were had thought of seeing it at Morrison, or Gasconade, or Chamois. But those seemed like they might be rather crowded. Also, they were farther away.

Bonnots Mill turned out to be a good choice for us. There weren’t too many people gathered to see the train go by; I think they were all more or less locals. Several of the “advanced case” railfanners were driving along with the train’s progress, stopping here and there to watch it go by again and again. But they were absent from Bonnots Bill.

But Bonnots Mill is off the beaten path. If you were a railfanner following the Big Boy along west US 50, a detour to Bonnots Mill is about 6 miles (one way) from Loose Creek, or 11 from Linn. With that detour, you’d miss the arrival of Big Boy at its majestic entrance in Jeff City!

So we opted to view it at a tiny, historic town, where it would blow past us in less than a minute.

Unbeknown to us, Big Boy was delayed from its published schedule; after departing St. Louis, it was only scheduled to stop for about 15 minutes in Hermann, then arrive at Jeff City directly after that. But it made two unscheduled stops before Hermann: one at the Transportation Museum in St. Louis (where there’s another Big Boy to see), and one in Washington, Missouri.

So we got to Bonnots Mill about fifteen minutes before we thought it could arrive. Then we waited quite a while, wondering what the holdup was. How long did it take to get from Hermann to Bonnots Mill? Should’ve been a half hour, at most, right? But there was no way to know; no cell service in Bonnots Mill.

So we, and the other folks who showed up, waited patiently. Boy was it hot! But we had fun poking around, walking along the gravel road, looking at flowers and roadside weeds, wondering if Krautman’s Korner will ever be used for anything again, wondering if the Hotel Dauphine is getting much business.

Bonnots Mill has so much potential as a quaint getaway, or a stop along a Harley poker-run trail, or maybe a place to hold business retreats. Being right on the Osage River, where it joins the Missouri, it would be a good place for a boating or fishing outfitter. There’s a public river access nearby. I’ve blogged about the Bonnots Mill fall church supper before. But unfortunately, much of the historic downtown is deteriorating. Crumbling.

Anyway, we’ve gone out of our way to see these historic trains before. Like in 2011, when we saw Union Pacific 488 come through. That’s a smaller train, but it was incredibly impressive. In 2021, we saw the Big Boy 1440 as it came through Osage City, then we visited it in Jefferson City, where it made an official stop. The next day, we watched it chug through nearby Cole Junction, where my great-grandpa Renner used to work for the Missouri Pacific Railroad.

So this year, after spending a night in the railyards near the State Capitol, on the morning of July 21, Big Boy left Jefferson City with a whole bunch of LOUD hoots of its horn. It echoed all over town. It made me think about the days when steam engine horns filled the air of this town regularly, and people rode trains all the time.

If you get a chance to see one of these vintage locomotives, go see it, even if you only see it as it chugs by. I know you’ll find it compelling.
