Will the 4-8-8-4 Union Pacific Big Boy ever return to rails?

Dear Brak710101,
A new Big Boy costs $265,000 in 1941 money. That’s a lot! When a railroad makes that kind of investment, they ensure that the minimum curve a locomotive can go around is a curve that the locomotive would not derail on. Additionally, it is much more likely that some of the wheels would derail, rather than the entire locomotive rolling over.

Most sincerely and repsectfully yours,
Daniel Parks

Man, why are you denying it. [:(!] I saw it to on MSN. The Big Boy will Ride again![:D]

You wont ever see a Big Boy again operational.

Hello Everybody, I’m a new member and regarding your question to will a Big Boy ever be restored. I was reading somewhere that UP’s chief steam administrator said that the UP does not intend on ever restoring a Big Boy . They already have their hands full with the 3985 Challenger. They can only run the 3985 in so many places. There are no turntables left to turn the Big Boy, only a wye. But if a Big Boy was to be restored, it would be my bet that 4014 would be the one. It’s in excellent condition from what I know. Hey , I would also love to see a Big Boy roaming the rails again, maybe a doublehader with the Challenger, ( Here I go dreaming again) but anything is possible

I’ve been down to Pomona, where X-4014 is displayed, & let me tell you that
other than the costs of coal, oil, & water , this guy is in good enough condition to
operate. The only reason I doubt it will run, is that california has sharp curves & small turn-tables, but heck, SP’s cab fowards had no trouble, & niether does the preserved Santa Fe 4-8-4 3751today (true it is smaller). If Doyle can
restore a pile of scrap, im shure someone can restore an almost brand new 4-8-8-4.

Ps. Im only 15, which shows the legacy isn’t going soon .

and a Big Boy wont run in your lifetime.

No offense but you are 15 and did you do a hydrostatic test on the boiler for integrity? Have you checked the flues for leaks? Have you torn down all the mechanical components to detrmine their ability to be rebuilt? Have you checked the tender for leaks? How about all the slip joints for the articulation? Or does it have a nice coat of paint that hides other issues?

ndbprr is right, although I said that the 4014 is the best preserved, does not mean that it’s capable of operation again. Just because it has a great paint job and all the bearings and rods are well lubricated (from what I read) does not mean it can operate. There are millions (lol) of problems that can plague a steam locomotive like firebox, flue sheets, smokebox, dry pipe, cracks in the tires, etc, I could go on forever, but if somebody comes forward to donate a few mllion dollars to get the restoration progress going, anything is possible.

Paint isn’t what makes an engine run obviously ! When I said (good condition) I ment
no holes in the boiler, cylinders, or tender,(unlike most outdoor display engines in southern CA),& a cab where the controll’s anent beat up. I admit, I didn’t check the safety valves, the inside of the cylinders, or the injector pump, but heck I wasnt planning to restore it.

I know it would have to go through a thourogh checkup, but from Ive seen enough
to know it isn’t impossible. True everything you said, would need to be checked, &
much more, but like I said its in pretty good condition fron what I saw, including the
tires & much of the firebox.

I’d be willing to bet that the engine if nothing else is wrong and could be fired today is loaded with asbestos insulation. It could cost easily $1,000,000 to just rid the engine of it. It will never run.

The cost of the removal of Asbestos on a big boy would cost no where near $1,000,000. Probally the cost of removal would be $50-60 thousand dollars. Removing Asbestos isn’t the hard part, it’s preparing and cleaning up that is the real cost. I’m a volunteer at Steamtown National Historic site in Scranton, Pa and we have a Boston & Maine 4-6-2 Pacific 3713 under restoration to operational status and the cost of removing the Asbestos for that engine just around $25,000.

Ndbprr if I was 90yrs old, I’d doubt if it would run, but im only 15, & if im sucessfull
in my careerr, I’ll find a way. Where there’s a will there’s a way. I dont know if one
will but no harm in dreaming, anyways I’m sure if someone were to do it, enough
people would send in donations to get the project somewhere.

It will happen some day! even it is just fired up for once a year and run back and fourth on a section of track, it will still draw crowds because its running!

uh, the Big Boys produced over 6,300 hp and had 135,000 lbs, tractive effort, those are conservative ratings, in tests, the Big Boy was able to produce almost 140,000 lbs tractive effort. -“The worlds largest Steam Locomotives”

4500 tons for a SINGLE locomotive Big Boy, I know that multi unit diesels can pull much more but Im sure that if you did not have multi uni diesels, and compared one diesel to one big boy, and such, the big boy would probly win.

The key word is 5.5 mile long Fully Loaded Train

This whole thread needs to die IMHO.

Allright guys,it’s time for a little reality to settle in. Big Boys are great locomotives,and pulling a five mile long train would be an accomplishment. Let’s look at tonnage ratings for a minute. They were rated up a 1.5% grade at 4,500 tons,and may have pulled more. On level ground,I would not be afraid to couple 16,000 tons behind one…just don’t put the Streamliner behind me while I’m doing it.

The reasons one will not be restored are as follows:

  1. High cost with nominal return.

  2. Limited operational area.

  3. Clearance issues:3985 will not run again offline because of this. The overhang as the boiler takes a curve has a nasty habit of fouling other tracks as the 3985 found out on the Clinchfield a few years ago.

4.Steve Lee has said he will not restore one.End of story.

In the Pentrex Video Last of the Giants, vol III Steve Lee said its not feasable to spend 2-3 years of the entire steam budget restoring something that can only be run within a very small area. It wouldn’t be able to travel like 844 and 3985.
