Is There Really A Market For These?

yes there are event exclusives with white shells that come with decals and can be colored on the kids then draw and put stickers on them.

Is that what they are...event exclusives? I do see a lot of these available at Yahoo Japan auctions and wondered. Can't you get the same invisible effect by just removing the shells of our existing trains? I have also seen plain plastic white shells and wanted to know if anyone used them for painting in their own scheme.
