That's another step I need to investigate, ballasting. Thanks for the referral to Dennis's book which should provide the information I need. In my "newbie" state of mind, I was (am) concerned after reading some blurb on the internet that ballasting debris sometimes may get caught in the running gear of a locomotive and "gum up the works". The "jewel" of my small collection is a Lionel 2046 that has been completely overhauled so I certainly do not want any issues with ballast finding its way into the moving parts of this find locomotive.
I assume the glue (and Dennis methods) will (should) prevent this from happening?
