Modern loco air conditioner

NOt that particular one but  PSC makes them in brass and Atlas O had them for their GP60's... both squarish box type and not the "RV" type shown in your picture.

Thanks curve, I'll probably try to make them out of styrene and settle for close enough.

Thanks again,

Super

Travis,

I have an MTH GP38 in BNSF Heritage III paint that has somewhat similar (but not exactly the same) air conditioner units on the roof. I can't tell though if they are add-on details or are cast into the roof itself and painted. I don't think the MTH engine had these details when first issued, which might suggest it's an add-on detail. But there's a little paint bleed over to the roof which suggests it's cast-in an painted. I suppose MTH could have modified the tooling that way.

Even if they are separate parts, they might not be quite what you want and whether you can get them from MTH is anyone's guess. If interested I'll grab a photo of what they look like and email it.

What!! air conditioners in these things now??

If all else fails, I can probably draw one up for you in 3d cad.  You could then get the parts printed on Shapeways or through a local 3d print shop.  All I need are dimensions and time.  The better the dimensions, the faster I can draw it and the better the results will be.

Hit me up if you decide to go this route.

Lionel also has a roof mounted air conditioner on their Vision Line Genset unit.  It is not as tall as the one pictured on the GP39.  Perhaps they sell the part separately.

I make my own, I use a HO diesel roof fan to make the fan on the A/C unit.

Rich,

I had the exact MTH H3 loco you're referring to with the air conditioners on top. I recently sold it and forgot to get the dimensions of the air conditioners. I can't remember exactly if they were separate pieces are cast in either. If it's not too much trouble, can you get me some measurements on those. I'll probably just fabricate some out of styrene similar in length of the MTH design, but probably a little taller.

Thanks,

Big train,

Right now I'll see if I can scratch up some reasonable stand ins, and if I can't acheive the look I'm after, I will contact you to go that route. Thanks for the offer!

Gregg- Thanks for your response. I will take a look at Lionel to see what's available.

CBS072-Thanks for your response. I like your Topeka cab loco, looks good!

Sure. I'll take some measurements and send them to you along with some photos.

I've decided to bight the bullet and do a pattern for one of the A/C units so I can cast them in resin for anybody who wants some. It will be similar to the one shown on the BNSF loco at the intro of this article. It's small - only about 24" x 36" x 8". The casting will be smooth in contrast to a 3D rendition that would be grainy. I should be able to have photos by Tuesday.

Stay tuned!

Tom

Pattern finished. Photos tomorrow!

Tom,

I'm tuned in and ready to see how this turns out Thanks!

i decided to do a second pattern. Now I have two versions. Making molds today and casting tomorrow. Photos then...

Here are the promised shots of the two A/C systems. They are cast in resin and are sold in pairs at $5.00 per pair (two of the same). Postage is $2.00 per order. the smaller one is used on work equipment, cabooses and locos while the larger is used on locos.they come unpainted. 

Tom,

The smaller AC piece you made looks like it will nicely represent the modern unit that I'm trying to do. Thanks for offering these. I'll email you soon.
