Where can I find replacement trucks and or couplers for old versions of these cars. They all have Horn-Hook couplers and I would like to give them Kadees. Any suggestions would be greatly appreicated.

Took home two Accurail Center flow hoppers to work on today from the club meeting. As usual I forgot to take pictures (getting 6th graders to sit down and stop being grabby is harder than herding cats) with all the chaos, but here at home I got some. Overall it is a good kit but getting the detail parts in was a pain and a screwdriver/drill is a useful tool for making them larger.

EDIT: Changed name since adding more cars.

I have some news that the Museum of Science and Industry here in Chicago has some items being auctioned off. I am actually quite disappointed at this as they have been there since they opened (I believe). Below are photos of the items and links to the websites. I am not sure what everyone else thinks about this though in my opinion i don't think it should happen. (not that I know what we could do)
