I had a childhood friend and model train expert build the custom HO train set below for my son's 12th birthday, yet now my son is in college and all it does is take up space. I am looking to sell it, but it needs some maintenance, technically everything is sound, but the track is dirty and the main engine may need work as well. 10 years ago, we used to use an eraser type pad to clean the track, but I cant seem to find it or remember the name. Any tips on maintenance? or what this piece is called?
Any advice is much appreciated
