Ooh. Those are also on my "maybe some day" to do list, so I definitely encourage it! :)

I do like the small coil cars and plan on doing liveries for them in the future when I get around to it. I also want to try my hand at what I call the "Thrall Special" coil cars: The first generation of NS Thoroughbred and Conrail CoilShield cars because they look very very nice.

Yeah, the same reason was why I did my shorter coil cars. I saw those all the time on trains near me and liked them better than what existed in RL at the time.

I was in the market to make what I see around my area. The flats are a bit unruly, but I think in my mind they look a little better than if I shortened them just to gauge. The flats probably aren't practical on small layouts, however I believe the spines make up for it. The GIMX 5-set I know is getting taken off trash duty and put somewhere else as the NKLX Spine Flats are replacing the old GIMX equipment in my area.

Yeah, but I've been around the community long enough to know that there are people that will assume they're stolen and make a stink on the official discord, just because they like doing things like that.
I looked, just to see if they're close enough to what I made that I might use the articulated ones. I was very tempted to do those instead of the ones I did.
The long ones are nice, too, but I'm not a fan of such long railcars (unless they're overly complicated twelve axle things. ;) ).

I did the containers from scratch, they're not yours. I'm not really one to steal the models of someone else.

Pre-emptive statement: I've looked. I can't tell if they're my containers, because I don't care enough to pull the model files and look at them in Blender. I don't think they are, but even if they are, EQReports has my permission to do this. Don't report them.
