Now I think the problem with my rail glide is that the new wire I got with the light socket base is thicker and firmer than the original Lionel wire used? Also, I slipped the new wire under the wire holder by the "rail glide" which is supposed to move up and down freely. Well, I think the new wire is too firm and is the culpert not allowing the "rail glide" to plunge up and down freely. I still need the little plastic spacer there but IF I remove the wire from the wire holder it has a lot more "movement" up and down.
QUESTION: Will the wire holder short things out if it comes in contact with one of the copper spring braces?
