This is a stunning shot, and the resolution is top notch to boot. 2 comments:
1. For the "all tank cars on your layout should be black" general statements, you can see all/most lettering on 12 tank cars. 5 out of 12 of them have some sort of Dow 2 inch or larger lettering, or logo, on them.
2. GATX 76577 in that photo is an 8000 gallon 1952-design welded tank that matches the Tangent release from 2 years ago.
Thank you for finding and sharing Bob!
