C.W.,
Thanks for your reply and thoughts on vendor parts.
Although I agree the TCA has little to do with Vendor repair and replacement parts, They do have on big advantage. Like the LCCA and LOTS, they represent the bulk of the toy train people who buy those parts and repair trains. They did successfully require the vendors to mark their parts "R" for reproduction or replacement parts. It's not perfect but it works. I was only recommending that one of these organizations take a look at the problem and see if the situation can be improved. Depending on the manufacture and sellers of these parts has not worked. Another problem associated with this problem is that the parts manufactures are not identified. I would think the manufactures would be proud to identify their merchandise if they are legit and do manufacture and sell quality functional parts. The TCA's roll could be something as simple as maintaining a file of problem parts to access. The sellers or the middle man could also be of help in evaluating and certify the parts their going to resell.
