In the eighties b/4 discovering 2r 0 scale, I had #1 scale 1/32 trains on white carpet using Lagas Creek Scale track. I saved the carpet by using 6 mil poly cloth under the track. Glad I did. When it came time to relocate the trains there were grease markings on the plastic interface but clean white carpet!
Agreed with the negative comments. That guarantees a time out of anyone's visitation privileges.
