8500 HP 3-unit turbine Union Pacific

I'm Edwin also on this forum USA O scale in The Netherlands and did a lot of pictures of my turbine 30 was talking to do more detail on the engine so maybe nice that this one has is own I'm looking for detail pictures and drawings of the engine in the B-unit you see on the picture of my o scale model Overland did a great job but not in detail yes better in ho scale see also picture.

O scale version.

This under is the ho version from Overland.

My question to all railroaders if there is drawings or better pictures that I have, hope you can help me...

From UP148 you see beautiful weathered engine by Lee Turner the O scale version but I want to go further to add all pipes and other parts on the engine if possible.

What I found are those pictures.

I hope that someone can help me I know there are Blueprints but I think there must be something of the general Electric Engine, Overland got it from somewhere.

on the top of the nose that green is fading over the years because of the sunlight what Lee Turner did is more than awesome, thanks UP148 of the beautiful pictures that is what I want and will do the same when the model is ready definitely an example for me. You see on the picture I done the horn yellow was from overland high gloss silver.

Under the weathering from Lee.

Very nice. For what it's worth, "Alco" had NOTHING to do with the design and construction of the various General Electric turbine electric locomotives.

ok, didn't know so I learn  I want everything to know about the turbines have books yes but now I go to do something with this project was standing still for years always dreamt about it to super the 3-unit.

OK, this may provide a starting point:

This page has a couple of cutaways showing the drive train with turbine and generators, and the diesel in the forward unit: http://www.oil-electric.com/20...brash-ups-gtels.html

And here's a closer shot of a turbine before installation, with some piping detail on one side: https://cdm16694.contentdm.ocl...16694coll20/id/2694/

I have a couple of gas turbine books but have not seen detailed drawings of the turbines themselves. I know that these have been modeled in HO in some detail but not where the maker (Overland) sourced its info.

BTW, I understand that Alco was involved in at least an early experimental model, numbered 50, that was tested on the UP routes but never owned by UP. Obviously the turbine itself was built by GE.

Thank you I hope to find drawings some day.

I thought Id never own a Three Unite Turbine So I wrote UP and asked If I could obtain drawings, they said that the drawings for the 8500 hp Turbine had gone missing years ago, and they simply didn't have them and couldn't help me. I do now own  the Overland Model in O scale. They must be out there some where, accurate models do get made???  I also had anticipated the drawings for the S-1 Pennsy steam Turbine in Mainline Modeler but I dont know If they where ever published, before it ended publication.     cTr....

I do know OMI imported at least one HO example (Diamond Series I think) with turbine engine piping inside the "B" unit. Not sure how complete or correct it is, but I'll bet it's right.......Tom was a huge UP fan. Maybe OMI would share their drawings if they still have them and this would be my 1st contact.

I JUST SENT BRIAN MARSH AN EMAIL ASKING THIS QUESTION.

I will also send an email to Dick Harley (UP Guru), as he was once a strong member of the UP Historical Society and had ties to the museum.  He's forgotten more than most will ever know.

Dear UP148 is there maybe news of the research from Dick I hope he find something about the turbines I'm also very curious under the B-unit not any picture gives me how it is. The overland model is nothing underneath it is completely smooth see example.

hard to see on this picture

The best picture (under) I found on internet and hard to see under the B-unit.





This is what I hope trying to achieve this atmosphere light weathering and what Lee Turner did.

Well, so far I'm shooting goose eggs on responses to two emails each. I may try to call Brian next week as maybe he's just too busy to deal with such items without direct contact.

Dick surprises me a little, as he's been very responsive in the past and we've worked together in the past, but we all live busy lives and he can't possibly share our interest/excitement to do this project, so I'll give him a pass and send a 3rd email next week.

One the glare shield paint, that was done by the former owner (Greg Bergman) not Lee. Lee enhanced it with his weathering, but it looked great even before that. Greg also painted the sun visors the same shade of green.

The color is Tamiya XF-21 Sky and he applied it with a brush directly from the bottle, after carefully masking off the area. He thinks he hit the area with steel wool before applying the paint, which sounds like a good idea to me.

I won't give up Ed, until it looks like I'm harassing these guys...I don't want to wear out my welcome.

Maybe reach out to Scale trains as the recently produced highly detailed HO versions along with N scale. I believe they have videos of the process of them laser scanning number 26 in full 3D. They may not release everything but maybe could provide pictures.  I wouldn't expect them to provide any 3D drawings or anything of that nature.

Indeed they made one of the best turbines in ho, scale Scale Trains did a fantastic job with there Museum Quality Models and a good price I think. But what I saw is not the details where we looking for all the pipes in the GE-chamber centrifugal-flow gas turbine what Overland did in there ho brass turbines. in O scale you can go much further in detail and complete the turbine I hope to achieve that. Maybe I try to contact them😀

The turbine guts will be tricky since they are not in the unit. But it's worth a shot as there's no telling what else they dug up in their pursuit. The museum model they put out rivals and beats any brass version I've seen of it in any scale. And the price comparison just really seals it for me.

Yes they are beautiful I think to buy one the price is very good and the pictures on there site of the turbines are awesome.

Well, I heard from Brian at "former" OMI and I must say, he's always been a gentleman....just no help in this situation. So, I'll continue pursuing other venues.

Greetings.  I regret I do not have these drawings that I can put my fingers on.  We no longer import and none of this information is readily accessible any longer.
Unfortunately I cannot fill the requested information.
Warm regards.

Great video Rusty!  I took some 35mm photos of it and a Centennial #6930 sitting side by side in south KCMO on storage tracks.....before the trade/move to IRM. I was already "ate up" with turbines at the time and had previously read they all came to to KC to be scraped....so this was a real surprise. Photos are not dated, but pretty sure this was mid 80's and I believe it sat there for the best part of the summer.

Since I had no permission to be near it, I photographed it from the ground and climbed up on top for roof top detail photos, but never got in the "A" or "B" unit like you did.  I figured being inside might be harder to explain to security/police/??? than just climbing around on it....but no one came or cared. The tender was painted black at that time.

At the time, Intercontinental Engineering was removing the turbines and reconditioning them for barge use.  I never heard if they were successful in that application or not.

I thought the turbine powered the trucks on both units and the diesel only the front? Also if I recall from what I read only two axles per truck were powered but don't recall what the configuration was.

Nope, there were 12 traction motors.  Having A-1-A trucks would've negated some of the advantages of the turbines.  The same for have the A and B MU.  Otherwise you'd just have the B unit pushing around dead weight on the road.  I recall KCRM discussing "exchanging" two traction motors for a welding rig from Intercontinental.

I suppose it's possible the hosteling diesel only powered the A unit for poking around light in the yard, but I can't really say, I haven't located any document to prove one way or the other.  The diesel was 850 horsepower motor by Cooper-Bessemer.

Note #1:  The 18 was used to switch the dead line at Intercontinental when needed, as it was the last unit in line.

Note #2: Neither the 18 or 26 were donated by the UP to the museums as they no longer held title.  They were donated by Intercontinental Engineering.

I hope we have it some day this is the best picture what I find at the moment you see a lot of pipes can you imagine if this is on the model. I believe there are many pictures out there also pictures of the factory the turbines are build. I think a lot was photographed in that time of which one I'm showing now.
