Included is the original 4-car 30-6113 set (B-E) from March 1999, as well as the add-on two-car 30-6126 combine / diner set. All interior lights and couplers were tested and are functional. I have spotted the following flaws with inspection. The “B” baggage car has a scrape on its roof, seen in photo #4 (above the “t” in “State”). Small stain on “C” coach car roof, seen in photo #9. The “D” vista dome car has? Stains of unknown origin on roof, possibly smoke fluid residue, seen in photo #14; did not attempt any deep cleaning. Rubber diaphragms have mild discoloration/powdering that I suspect could be revived with an oil, or might just be dust. As thorough as I think I was, I may have missed something, so please review photos and reach out with any questions. I hit the photo max on this one. These were all taken care of in their heyday, which were part of a family member’s collection.
