I read the Spooks message concerning using paint to keep traction tires on the drivers. My problem is I have a brand new Berkshire that has a completely broken traction tire and Bachmann has no more. I can only work on the layout in the winter and I had purchased this one last May 2016, but kept it boxed until a few days ago. Ran it around the layout a few times testing it's new ness and noticed a broken traction tire and a chunk of it missing. It is probably somewhere in a tunnel cause I can't find it. So is there any other way to replace this traction tire or something else that will work? Appreciate any suggestions. RG
