A few years ago there was a thread about carbon black covered hoppers.

At Trainfest here in Milwaukee this weekend (which is always an opportunity for manufacturers to introduce new products), Scale Trains showed two new carbon black cars in their Rivet Counter line: a Thrall 4727 cubic foot carbon black car available in Columbian Chemicals, DeGussa, Equa-Chlor, and Sid Richardson (four road numbers each) and a Thrall 5750 cubic foot carbon black covered hopper in two versions: late 1970s in Cabot, Columbian Chemicals, Sid Richardson, and Witco and a 1980s version in Cabot, Columbian Chemicals, JM Huber and GACX. All of those are also in four road numbers each.
I believe these cars were announced at this summer's NMRA train show.
These looked like beautiful models to me, and yeah, priced accordingly. ETA is July 2017. If Carbon Black covered hoppers in the more or less modern era are of interest, you may want to put in your order now.

I'm just a dude with a bad back having a lot of fun with model trains, and finally building a layout!
A MRR article on scratch building a Cabot carbon black car was reprinted in Kalmbach's Easy-To-Build Model Railroad Freight Cars.
Copies occasionaly turn up on eBay and can sometimes be found at used book dealers.

I can remember seeing lots of the Sid Richardson cars in West Texas in the 80's. Thanks for the heads up on the new models.
Nice-looking car, but too modern for my layout.Here's the older style carbon black covered hopper from Rail Shop (the prototype was built in 1934):
