Laying Peco code 55 track using caulk: problems

[Tyson Rayles]

I have been using Peco code 55 for years but I have never and will never use caulk so I can't help you there. When you cut the rail if you will use a small file to clean up the ends and taper them slightly the joiners will go on a lot easier. That said you should never depend on the joiners for contact. To me the joiners are for keeping the rails aligned, solder is for contact. I would suggest you use Elmer's white glue instead of caulk, that way you can change/reuse/relocate the track forever by spraying it with warm water, letting it soak for a few minutes then pulling it up and relaying it after cleaning it up a little. If you use the caulk I don't know how you could ever make a change or reuse it. And of course clean up is a lot easier with the Elmer's.
