I also really enjoy this thread, in fact it's the first one I look for when I open the Tinplate directory. This week I didn't get much train work done as my real job keeps interfering. Below are a couple of photos of things i am working on. The first is a 116 hopper that I bought on Ebay. It had been repainted silver over the original maroon and this was rough so I don't fell bad about repainting it to go with my other B&M trains. Maybe by next week I'll have it finished.
The second photo is a 439 Panel that was rusted and so tarnished all the brass looked black. I've repainted it and am in the process of cleaning the brass. When I'm done cleaning this up it will be for sale if anyone is interested. It will only have 4 knife switches but it should look pretty good when done.
