Union Pacific Railroad 4-8-8-4 Locomotive No. 4012

History: Brief background on the 19th century history of the Union Pacific Railroad appeared in the discussion of Union Pacific Locomotive No. 737. By the 20th century, the Union Pacific had gone through the processes of bankruptcy and reorganization, and early in the 20th century experienced rejuvenation in the hands of one of America's foremost railroad managers, the legendary Edward Henry Harriman. The company had lost its lines south of Denver extending southeastward across Colorado, New Mexico, and Texas, as well as its narrow gauge lines into the Colorado Rockies, during the bankruptcy of the 1890s, but under Harriman, it experienced not only a complete overhaul of its physical plant but also new construction across southwestern Utah, southern Nevada, and southern California to reach the growing metropolis of Los Angeles as well as a tidewater port at San Pedro. Thus the Union Pacific of the 20th century extended from Omaha to Cheyenne to Ogden to Portland, as well as to Denver, Salt Lake City, Las Vegas, Los Angeles, and San Pedro. It also owned a line between Denver and Kansas City. It was, furthermore, a thoroughly modern and up-to-date railroad.

Union Pacific Railroad Engine No 4012 is one of eight 4-8-8-4 "Big Boy" locomotives that have survived out of 25 that were built and operated. Its class remained among the largest steam locomotives in the United States, and locomotives of this type operated on no other railroad. Built in 1941, Engine No. 4012 is the epitome of modern, main line heavy-duty steam motive power. This class of engine was created to haul heavy freight trains over the mountain divide known as Sherman Hill between Cheyenne and Laramie in southeastern Wyoming and further west, across the deserts and then the Continental Divide in south-central Wyoming and the Wasatch Range in northeastern Utah, on the run between Cheyenne, Wyoming, and Ogden, Utah. The engine is one of 52 historic Union Pacific steam locomotives that escaped the scrappers' cutting torches. Engine No. 4012 is the only articulated locomotive (with more than a single set of drive wheels pivoting on more than one center) currently in the Steamtown collection. No. 4012 worked on the run between Cheyenne and Ogden for more than 20 years, rolling 1,029,507 miles before the Union Pacific retired the locomotive in February 1962.

He should be put back into service not left to rust. He still has the power to pull large loads even better than Dieseal.

I believe it's mostly a paint job, I dought they'll have her run again. That would be big money

well that's better than nothing and letting it rust, though they could probably move it inside for once...
yeah and at least 2-3 years...

I live about 40 minutes away from Scranton and love this place, but they really need to restorate many of their trains including Big Boy. I mean have fun raisers or something.

Since it is at Steamtown in Scranton Pa, which is a federal park, maybe they can get some federal stimulous money to restore it. A better use than some of the things the money is being spent on.

i wish! lol Al Gore would probably have a heart attack if a big boy ran again... freaking crazy environmetalists. personaly i'd like to see all remaining steam locos in the US kept in running order.
many are more powerfull than their diesel counterparts and each one running could employ more people per loco, and it'd stimulate the economy by creating mre jobs, but it's the burning of the coal that seems to be the issue. not "Green" enough. lol
heck i'd love to see a whole new chapter with steam locos with greater efficency using modern technology.

the Brittish just built a BRAND NEW Stem loco in 2008, and if they can do it, so can we.

Al Gore would try and stop the train LOL! But the main reason why Steam locomotives aren't used much is in the industry is because they cost alot of money to run and Diesels are more easier to repair and such. So far I haven't heard of any crazy environmetal groups trying to stop steam locomotives from running ohh and if they tried in PA they be Shot! The funny thing is Diesel trains are far more worse for the earth than Steam engines.

Oh yeah, can you link me that new Steam Loco please?

Yeah the expence of running a steam loco is very high, becasue of the cost of water, coal/oil, parts and workers. ect.
but even if they dont use and steam for hauling large loads, far more people would ride the rails if they opened up a few for passenger service. Just having the #844, #3985, and #4449, (among some lesser known steamers)isn't enough from most railfans.

and why can't somebody make a "clean steam" loco? it cant be that hard, even i've got several ideas...

I really agree with you on a "Clean Steam Locomotive" It can be done, maybe just use water and solar?

:icongaara2112:
Gaara2112 Featured By Owner Jul 6, 2009  Hobbyist General Artist
that was my inital thought. at this point i dont think solar technology is effecient enough produce enough electricity to power multiple massive heating coils... so i was thinking possibly solar and hydrogen fuel cell. but again the technology still has a good ways to go... wind is basicly usless if the train's not moving.. nuclear is too hazardous..

another idea is to move the cabin from the back to the front. espeially with neither coal nor oil being needed..
also, have a way to cool and re-use steam/water will greatly diminish the need for refueling stops.
and using a stream-lined shape will help with effecientcy at higher speeds..

now retro-fitting an older loco like the 844 may run into several issues because a lack of space, and design conflicts... espeicaly in the idea of cooling and reusing spent steam...

here's a sketch i did a while back for a "green" loco..

yeah and have a whole set of 5 miles of flatbed cars full of railfans and people upset w/ the gov. holding torches and pitchforks and waving the "Dont Tread On Me" flag. just to send the message "Get the Heck out of our way!" kick the dirtbags out of office and put real trustworthy people into offices. and have America be the leader of technology and innovation once again.
That would freaking rock.
Just Saying.
