The Roco rolling stock was pretty good for its time--the 1970s. I used to carry a small amount of O scale in my hobby shop back in the 90s. IIRC, there was the aforementioned ore car, a mill gon, and a PS-1 boxcar plus the EV caboose and F unit. The mechanism of the F was on the level of Tyco's single-truck HO F-7. The thing that really started the revival of O was the advent of Intermountain's 1937 AAR boxcar, quickly followed by a steel reefer, and ultimately a GP-9. The latter was highly detailed and made the Weaver FAs and RSs look pretty plain. P&D specialized in after-market drives for all of those units, plus super detail kits.?

Jerry Porter's HO version of the 1937 AAR boxcar really pushed the state of the art forward. He and Jon Verser were partners at some point, and Jon brought out the '37 AAR boxcar in S. In those days, the movement toward China was in its infancy and Intermountain tooled the HO, S, and O cars in Longmont, CO.?
