Per Jim's request, here are a few more (I didn't post the ones that others have posted) :
I have all three road numbers of this outside-braced box car in yellow, then stumbled across a green one. These were originally done by Crown Model Products and were later sold under Weaver.
Here's the green one from Crown Model Products (forgive the focus, but this was the eBay thumbnail)
I believe these stock cars also started out with Crown as well (can't recall)
These are definitely Weaver/Quality Craft
The mechanical reefers were sold with or without sound (mine are without). The ones with sound are being posted on eBay at a pretty high price. ITT Products sells a sound board available with mechanical reefer sounds. They're at GL (ittproducts.com) I was able to obtain some 36" wheels and extended coupler boxes and converted all of them to 2-rail. A word of advice: If running on a track with multiple trains, run with the refrigerator unit foward. One of mine got rear-ended and the refrigeration end got damaged pretty badly.
