several years (decades?) ago Model Railroader had an article and plans on a plastics plant served by the Southern Railroad. Here is my selectively compressed attempt. This particular version is a low relief model, with only the rail side half being modeled. It is built out of plain 0.040" styrene sheet and 0.030" space corrugated styrene siding. This photo shows what I call 'stage 2', all the major structural work done,a base coat of paint applied and the beginning of surface details such as guttering and downpipes
