- Here is my review of the recent Class One Model Works "Old" (or Small) Transformer. This is a very nice load, with only a few items "wrong" or that can't be corrected. In my rambling, babbling style I go over what I see from a Transformer Guy. For those that don't know, I have been in the Power Transformer Repair industry for most of my 35 years in the business. I have worked for GE, ABB and now IPS- all through acqusitions, not changing jobs.
Overall, this is a very good Transformer load. It is a GE Transformer, likely built in the 1940s or early 1950s. I found a few things off on the model, and these are covered in the video. With a few simple additions and some paint, one can make this into a great looking transformer load.
I only have the Old Transformer- I don't have the "Large Transformer- Modern", thus I can't properly review that model.
Special thanks to Stephen Priest and Mike Brusky from Class One for corresponding with me. It is greatly appreciated.
Thank you for watching!
Hey, Rob, as someone who doesn't know squat about transformers, I really appreciate the crash course about them here. Well done. Thanks.
I know nothing about transformers but to me it looks really cool, especially when loaded on the depressed center flat car. Thanks a lot for sharing, I really enjoyed the video.
Outstanding description of the transformer load. I am just starting to build loads, this video show's me the detail one can achieve. Thank you.
This was very helpful! I was wondering if the transformers were black, blue, or green, this cleared this up!
I believe the two "protrusions" at the top on each side are the tie down points for chains during transport. I've hauled smaller transformers on a flatbed and that's where the tie down points are. There should be a hole to feed a chain through and then hook it back on itself.
Thanks for posting this. I've already received my transformer and the Class One C&EI car. I now know how to upgrade it some.
Haha! I bought a C&EI car also. Bought the drum load for the C&EI car and the modern xformer for the Athearn TTX depressed flat. Great looking car & loads!
For the pressure relief device maybe you could use a locomotive steam generator air intake 'dome'? I've seen some pressure reliefs that kind of look like a squat mushroom which resembles the Vapor air intake.
Not a bad idea...I'll have to look at other detail parts and see what can be done!
Very cool. I'm confused by the number of cover plates on the top deck. I'd expect three larger high voltage and three smaller low voltage bushing covers , or four smaller low voltage bushing covers. I bet I'm confusing inspection covers with bushing covers though. Your attention to detail is impressive. Where I used to work some of our units lasted 60-70 plus years because we only loaded 1/2 nameplate. Plenty of tank oil leaking and weathering opportunities at HO scale :)
I agree- depnding on if was Wye or Delta, there should be three or four (the Neutral) openings for the HV and LV bushings. Maybe three manhole covers on a unit this size. Likely a PRD on the cover. But, it is not bad for what it is!
@@robbennett1965 agreed …. Great modeling sir.
Thanks for adding your Transfomer expertise . Can you please add the Cal-csale & PS brass valve item #'s?
Nice added details but you lost me on the parts.

Great video. Thanks for sharing.
Glad you are getting more content out again, I really like your modeling and your laid back style. I have a question for you transformer guy, I model the mid 1970's and is that still usable around then? Been thinking of one of their cars and wanted to do a load, would a used transformer like that be a viable item sold to a place in Mexico, or by the 70's would it be scrap metal? I guess what's the life span on something like that? I suppose I need to get a depressed center car at some point, just because they are so unique.
These units usally last a while, so this unit could certainly be around in the 1970s. We usually say the "life expectance" is 25-30 years...but I often see units at around 40-50 years old. Don't forget, Prolec-GE has a transformer plant in Monterray, MX.
Hello Stephen!! Could the double valve with the flange be a connection for oil circulating pumps? I have worked in the power industry for 26 years and I have run in to older main step-up transformers with circulating pumps.
Could be, but I don't ave any other pictures or the Outline, so I can' really tell!
hello stephen it's is randy and i like yours video is cool thanks friends randy
Rob, I have the modern xformer and was wondering what color I should paint it? I do like your color but for a more modern xformer should it be a lighter gray or a greenish color? Thanks! Can’t wait for the next video on how you tied it down.
Paint color is a Customer specification, but the "Standard" color from the late 1960s onward is the ANSI 70 Light Grey. I'm not sure what a good paint match is- I don't paint my xfrms 70 Grey. It is a light grey color. I have also seen dark grey, Berkshire Green, Desert Tan...there is a wide range! I think nearly any light grey would work.
Rob, I found Rustoleum Army Green paint that looked like a close match to the Berkshire Green. I then hit it with a gloss coat and I think it looks great! Now to tie it down. Thanks!!!
If that was a new unit would the radiators be part of that load?
Usually Yes. In the transition era, they likely shipped on another flatcar along with the main unit. Nowadays they would go by truck.
👌👍
Any guess how much this would weigh in real life?
Weight can vary depending on several factors, but a unit such as this would be in the 60-90 ton range.
Never mind.. sorry I didn’t look for this first.
