Use the corners?
Here is an updated plan view of the room. As you can see I am short on space but if I am going to have a layout this is pretty much it. Telltale is right that it would have to be elevated so it would pass between shelving or anything else that might be on the walls. I need the alcove inset so I can maneuver around the large canvases. Obviously I will have to make adjustments but I think it is doable.

Your plan to have trains circling your shop is great. As is, it will be OK if the train is just sort of a background item for your other interests. If however, you have/develop an interest in operating your model trains somewhat like a real railroad, the I would suggest some changes. Please note, the operative word here is "suggest." What, if any changes you make, are strictly up to you.
One question I have is, do your other workshop area activities include any woodworking ones that produce sawdust?
I have my shelf layout in my garage (I'm married) and have serious issues with the dust from my table saw, band saw, sander, etc. I have shop vacs attached to all the major power tools which helps, but it still gets very dusty out there. I have an air compressor, and use it to blow a lot of the dust off things. Dust can get on the track and prevent the power from getting from the rails up into the locomotive. That's the reason behind my question.
Now the suggestions:
Unless you have your heart set on, or your children's college fund already invested in, HO-scale products, you might consider using N-scale instead. It would allow you to keep your shelves narrow, but go to a double track main line, which will double your train watching fun.
N-scale would also let you use 16-19" radius curves which will handle any passenger cars, or other long N-scale equipment made.
The smaller curves would also fit into the corners of the room a bit more closely. Those corners, and possibly the shelf at the upper right end of your drawing, could be expanded out a little without any serious intrusion on use of the general space I think.
On the shelf you could have a small railyard, or town.
In the corners you could try your hand at some scenery. A hill, a tunnel, a curved trestle over a small gulch, or whatever else you choose.
With your painting skills you would be able to paint backdrops to make any area of your shelf layout look much deeper than it is. The first photo shows what I mean. My shelves are 16" deep, but this scene is only 8" deep at the bottom.
Need more shelf space? Build your shelf layout like mine, with a very long shelf/top over the whole length of the railroad. I used a "bookshelf railroad" design from an old Model Railroader Magazine article. You can see how the design works in the second photo. The arches make the assembly super strong and support the weight of many books, a TV set, and other electronic gear on the top shelf. Those same arches also leave room for the railroad to run through the several sections of my layout with an unbroken, wide open view with no front supports in the way.
My basic section (photo 2) is 4' long, 16" deep and 16"" high. You probably don't want to give up the amount of shop space that 16" deep shelves would take up, but the sections can be made in any size. I have some that are 4' x 12"x 8" too.
I also have bigger sizes at the ends of my two-walls-only layout to turn the trains around on bulky loops of track. With your use of all four walls, you would not need any large sections, or want them, since you want to conserve as much shop area as you can.
Again all decisions are up to you. You may decide not to use the bookshelf idea, or to build one in a smaller size.
The files attached below have lots of information on model railroads in general and shelf layouts in particular. If you decide to stick with your original,very simple, concept, then a lot of the information won't apply to what you will be doing. However, if you skim through them, you may pick up a useful idea here and there.
Good luck & Have fun!
