What a great sight and sound from this engine. You feel the earth shake and stare in amazement as this wonderful piece of machinery from an era past. If you ever get a chance to see it, don't miss it!

at 0:38, wat is that noise?

[Charlesrandall]

I'm not sure but it sounds like a high speed fan. It was coming from the tender. I'm hoping that someone will watch this video will let us know. Thanks to you for looking at my video, I appreciat it.

I think that noise was the water pumps, or injectors pumping water from tender to boiler.

@844jim actually ive seen first hand 844 running 85+. I tried to catch her on the run on the UP main in nebraska but at 85 I couldnt keep up she was running a good 90+. She was built to maintain 90+ with a 12 car streamlined passenger train on level track. She was one of the high speed jets of her day and my grandpa took rode her to Omahah, NE back when he was shipped to Korea and remembers seeing her class running through town highballing.

@mynewpastime haha its not miles per gallon its gallons per mile! Steam locomotives being very inefficent with energy use (really bad compared to internal combustion) there is several advantages of steam locomotives. for one they have to actual top speed like a car engine, 2nd is that they can pull a train they cant start while diesels will start a train it cant pull (its all about how the power is lost and preserved to conserve power

@Dippojtagyta Challenger was a normal late steam era dual service locomotive that was used for freight and passenger service. They got bigger then that. Most people think Challengers big brother the Big Boy was the biggest of the big locomotives which is incorrect. The Yellowstone and Alhegany (sp) locomotives made big boy look weak in terms of size, traction force, horsepower, speed, and draw bar power (amount of power at tenders coupler).

That sound from the tender is the pump. This engine's first run was engineered by Forrest D. Wright, a graduate from the Oglala School for Indians where he learned railroad engineering and maintenance. The rear dampers had a bad draw. Opening the side dampers allowed too much air. The ATZ was defective and the gun had to be continually used.

@warlordx94 wenn ihr Deutsch könnt dann kann ich es euch sagen ^^ Das ist die Lichtmaschine ... eine Kleine Druckluft Turbine die an einem Generator angeschlossen ist und so den Strom für die Lichter und Funk erzeugt.
