A number of people have been looking for Atlas PS4750s. Nothing new there, but I did discover that the Weaver "PS2-CD", actually appears to be a PS4750. I believe (i could be wrong) that Pullman-Standard introduced the 50' covered hopper car as a PS-2CD, but as the increased the size of the car and the capacity from 70 tons to 100 tons, they cataloged the cars according to their cubic foot capacity. There were also PS4650's, and other variations.
So i put about 20 different Weaver PS-2CD / PS4750 cars up on the website. We only have maybe 30 different road names for them in stock, and maybe 50 cars total.
