Here are a few scrap loads for those empty gondolas.
This car is carrying the scrap motor parts that were left-over after making the coils of scrap wire in Get a load of this...(lots of photos)
Scrap axles and wheel rims from Rivarossi passenger cars.
Miscellaneous scrap, including blackened brass cuttings and wire left-over from other projects, broken couplers, a few disposable lighter parts, etc.
More miscellaneous junk: lighter parts, broken trucks, pen parts, etc.
This TH&B car is carrying a load of metal stakes from Athearn flatcars. The chemical blackener turned them grey-green.
Another load of mixed scrap from various sources. Prototype scrapyards pay better prices for sorted scrap (all one kind of metal) and steel producers often demand that certain types of steel scrap be kept segregated.
I hope that these carloads will give you some more ideas for making your own loads.
