Or...you could put 5511 (UP 2-10-2, dead in Cheyenne roundhouse) up there, remove 4023, run her through the shops and have TWO Big Boys (count'em, TWO) in service!!!

Now watch someone grab this thread and make it a "fact" on the web.

I don't see the point of dragging any iron up any hill for display. The day of outdoor railroad displays has passed. I packed the grease cakes and greased and exercised the valve gear with the power reverse on 5511, along with an oil-around a number of times over years. It's a very rebuild-able locomotive and would be a shame to put outside.

Hello,

This those in the know on this forum, with the 4014 being converted to oil firing, I recently heard of the potential for strong stack draft pulling the flame off the burner on oil fired live steam locomotives. Is this an equal risk on full size locomotives?

If a "flame-out does" occur how would you re-light under high load conditions? Seems to me you would quickly get the "white fog of death" in the firebox (volatized fuel oil vapor) flashing off the hot surfaces.....basically an explosive mixture.

Just curious if those on the forum could elaborate who have experience oil firing.....especially in response to wide draft variations from full forward gear to lesser demand after you hook it up. Obviously you would regulate the oil flow similar to adjusting coal stoker speed. How sensitive is the balance between oil flow and draft?

Certainly the 4000's didn't have a flame-out issue! They lifted large volumes of unburned coal off the grates on a routine basis! ;-)

Thank you in advance!

Sincerely,

Randy

I drove past the Big Boy/Centennial display along I-80 entering Omaha about nine years ago on a very rainy Saturday while driving to Colorado, and regarded it as a three-dimensional billboard for UP in it's headquarters hometown. While it is out exposed to the elements, I didn't regard the display as outrageous or in poor taste and appeared to be kept up and painted.

I know this is a little off topic but with the pride UP has in their history I feel a UP railroad museum showcasing surviving examples of their locomotives and rolling stock through the ages would speak volume to the masses. Seeing their progression from the last UP 440, to the Mikado, 9000, challenger, big boy, big blow, dd40x to modern day would make for 1 heck of a railroad museum!

Locomotive oil setups - the historic variety - are notoriously able to deal with a wide variation of conditions and changes and burn anything from jet fuel through Bunker C you have to melt down to make flow (but inefficiently). If conditions like water or other problems in the fuel combine with losing her feet, you can blow the fire out - but a good fireman can relight from the hot brickwork by opening the damper, a bit of blower to clear the box, and reestablishing fuel flow at the quadrant. Once lit, the fire can be managed back to operating conditions as necessary. To me, the challenge is designing the combustion engineering to set a huge coal burning firebox up for oil firing - but it's likely the UP did this figuring about 50 years ago or more. Starting from a clean sheet today, using light oil, we could do much more in terms of efficiency and cleanliness, not to mention firebox life.

The reason I always leave a bit of blower going, is that every so often, my (oil) fire might go out, and produce the deadly white gas. Maybe it happens if your engineer runs too far down in the corner with the throttle wide open. Maybe he has to suddenly shut off when he wasn't expecting to. Maybe it happens when you're parked in the station, with a Sunday school class looking at the engine. Maybe you get a slug of condensate in the fuel...

The way I relight is 1) DON'T TOUCH ANYTHING !!! If you had your fire set right, IT IS STILL SET RIGHT. 2) Shut off your atomizer 3) Count to three 4) Turn your atomizer back on.

That pretty much works in any circumstances. Would it work on a Big Boy ??? I don't know. It's the first thing I'd try if it was me. I'd also be scared to work on that thing myself.

By the way --- I toured the UP steam shops 10 days ago, I'M IMPRESSED, don't know about anybody else, but I like seeing that somebody is actually pulling it off. One thing that especially impressed me is that the guys told me that if I had their resources and tools, I could do it too... I'm not convinced of that, but I find their modesty refreshing.
