Union Pacific Big Boy 4014. The Great Race Across the Southwest.Chasing and Pacing! 

I recall standing next to the Big Boy in Scranton, PA. Even though I am a Navy man (used to really big machines) that Big Boy was the most awesome thing I have ever seen. I love how it wears it's mechanical nature on the outside for all the world to see. All wheels, levers, pushrods, combining into the soul of the beast. Who says computers are the pinnacle of mans creative genus? I say this is, fully created in the mind of mem who had to do the math and the work themselves. Their blood literally becoming part of the machine.

No matter how old I get I still love steam engines they play an important role in history and I’m glad that steam engines are making a return ❤️❤️ I live in PA and there’s an area called Steamtown and I have my picture taken right by a Big Boy ❤️❤️❤️

LOVE the sound of that deep bass whistle!

That whistle is the voice of a spirit from the great beyond.

After flying the Boeing 747 for 22 years I can say this old gal gets your heart throbbing every bit as much as a night takeoff on an icy runway in the night in a snow storm.

What a beautiful monster to see highballing down the main line again. I read somewhere that a common nickname for the Big Boys were "iron dragons" and listening to the whistle, I can hear why. One of the most complex and powerful machines ever built, and seeing one running full tilt is the sight of a lifetime.

It has to be a big thrill for the Big Boy engineers! -To experience the awesomeness from inside as well as hearing it outside, not to mention seeing all the Americans and others capturing the moments from roadsides and fields. 🚂

What a awesome sight to see a Big Boy running again!

I lived in Provo from 1993-2005 and for me, this was a great experience. Being the train nut that I am, I could watch this over and over and never get tired of it. It is some excellent videography. Thank you.

Your support for the free world will be remembered forever. Congrats on Big Boy's reappearance.

Brought back wonderful memories of me and my grandpa standing right next to a monster like this while it departed Everett WA station. Made me cry..

Took me 9 months to rebuild engine and firebox. At 6’5” 312 pounds I was brought to tears when I fired her. What ah beast. 1,250,000 pounds 14’2 tall 7, ooo horsepower. 135 feet long 11 feet wide. No joke here. Long live BIG BOY.

OH! What a POWERFUL machine he is! He appears to be speeding down, down, down the tracks of time, down through history! Truly takes my breath away. Thank you.

Love the chase footage. So awesome to see 4014 choochin' along at speed. I'd seen it many times when it was a museum piece out in Pomona.

The giant comes alive. And look how happy she is to be back in steam, and on the tracks. This is where all steam locomotives belong. Not rusting away as static exhibits in museums. In that state you can never get the feel, the smell, the look, the sound, or the beauty of motion that a steam locomotive represents. Excellent work UPRC. You understand the need and the feelings the public have for magnificent steam locomotives. Thank you for bringing her back to life, and allowing her to stretch her legs once again on the main line where she belongs.

Anyone who would fly out from Vermont to chase the UP 4014, can't be all bad...I chased one from Denver almost to Cheyenne years ago, nothing to compare with driving alongside that engine...GREAT video.

Absolutely love this segment !! In the wide open country this old girl really pours on the steam !!!

Thank You for fliming this I live in Provo Utah now days. However I grew up in the small town of Hinckley witch is 5 miles West Of Delta and when I saw the Train enter my Home Town County Of Millard County ( The Town Of Leamington ) I Started crying . Even as I wote this I cried.

A truly marvelous piece of human engineering, great to see it on the rails again!

Thank you, thank you, for the great video. A wonderful tribute to the steam engines of the past. And the great future of the USA.
