EMD SD45 - Union Pacific

I've been working on the railroad!
So, back to the SD45. I haven't nailed down the exact horn used by this number and at first I thought it might be the Nathan Chimes P3 but I think it might be a Prime Manufacturing 920. It can also be a Leslie. I started off with the P3 so I thought I'd soldier through it and possibly beyond what's needed for an overall locomotive model. No plans were available so I had to eyeball it with images of the P3 which required a deep search on the internet.
The mounting bracket was a little complicated.

Wow!

Thanks Bryan. It looks more like a polished trumpet right now but that's the fun of rendering. The material is Brushed Brass Metal Texture from Poliigon. I added the scratches in a material layer which if from 4K Imperfections.
I had some of the parts pointing in the wrong direction and fixed that since. It's too detailed to include in the final SD45 model or maybe not since I can always create a Thea proxy. I did the line work for the Nathan logos in Autocad. It wasn't that difficult since it's all straight lines. I'm able to reduce the amount of linework in SU by using Thea's bevel.
Now I'm thinking about modeling a trumpet.

Here's the Prime Manufacturing 920. It's a copy of the Leslie S-3L. It was a lot easier to model than the Nathan P3. The material is "Cast Iron Texture, Raw" from Poliigon.

This stuff blows my mind. I need to set my level back to beginner.

Thanks Dave. Practice, practice, practice. I think in this particular case it helps to be able to visualize distances and think proportionally such as if something is 20 inches long you estimate other parts of an object which may have a diameter of 1 inch. Then if that looks wrong try 1.25 inches, etc. I know in the case of design it's also good to step away from the computer and think about how you'll tackle a project while lying in bed.

This is the shutter and grille assembly. The shutters control airflow for air cooling. They're normally open. The inner grille goes on all three on each side of the locomotive. Omitted for clarity.

Absolutely stunning detail!
One of my first jobs out of high school was as an old school mechanical drafter. Real paper and pencils. I was creating drawings right down to nuts and bolts and welds for very large heavy equipment. I really appreciate mechanical details.
I often skip them in my SU models to keep the file size manageable. SU 2017 does not like large file sizes.
Again, excellent work!

I got the truck plans here. The Flexicoil trucks. I used photos and other sources to update those.
The other place was the Canadian Pacific Historical Association. Here's the search page. You have to register.
I found a lot of other plans there for cab, frames, etc. You can search for SD-45 or SD-40 (modify those).
Flickr is a good source too for details.
Other stuff here too.
