Yes, what year Cotton Belt (SSW) Equipment are you thinking about? 1950's? 1970's? Modern?
Modern Cotton Belt locomotives and rolling stock are made by Athearn, and probably Atlas.
Older Cotton Belt locomotives would probably be harder to find, but Stewart makes a nice set of FT's in SSW paint! :thumb: EDIT: Atlas makes SSW GP7's in a Daylight-esque scheme for their (prototype) frieght units.
Freight Cars would be made by a range of manufacturers, no worry there!
