Wonderful item, and the cars stay on better and roll better !
Indeed they are metal and may be used to replace the plastic wheels in their trucks. The problem is that they are completely insulated. I needed to replace trucks on lighted coaches; this requires that the axel and one wheel be electrically connected, they are not. I have purchased 36" wheel set and they are correct. No where in the specs do they say that these are completely insulated.
