Done the caboose. Just needs textures. Not sure what railroads though. Starfoxfan11 suggested B&O. What do you all think?
B&O didn't really have any caboose that would match that 100%
as far as fictional schemes that the B&O may have had, this is as close as it would have been.

Granted that is a wooden caboose, if you wanted to do B&O it'd really depend on the era.
If I remember correctly your diagrams had the L&N on them,
This looks closer to what your model is.

And even though this is a model, BrassTrains makes their models 100% based on the real thing, so this is what you made
