I am trying to model CMRX80033, CMRX80003, etc. I found this decal set (https://highballgraphics.com/index....-car-ti-pure-15k-gal-tank-cars-n-scale-detail), but am unsure what base model tank car to use. Any suggestions?
The Atlas Kaolin tank may be a good starting point. The capacity is similar to the 15K listed on Highball's site, but the Atlas 17,360 may be another good one too. That car is a bit bigger, but I think the shape of the tank is a bit closer to the titanium dioxide car. The Kaolin tank seems a bit more stout and just by looking at the photos, the diameter seems a bit larger. The 17,360 has better proportions to my eye, but the Kaolin tank is closer to the capacity and length of the Dupont car you want to model. I think it may be up to you, and you may even own these models and can investigate further than an HO modeler like me can.
