Thanks much for all the replies. My wiggle was fixed in about 3 minutes flat. It would not have been as easily fixed if the track was ballasted.
A few more random points: All of my frames are made from 12 ply ¾ birch plywood. That is a good thing. It is painted on the outside edge just for aesthetics not wood sealing. Admittedly 15 years ago every visible surface would have been covered most likely stained. I did not do that now. Every joint is screwed glued and tattooed. 90 degree joints have dado recesses. My layout would probably be considered sectional. I would not call it modular because it is not built to an established standard like S-Mod. It is currently 11 sections total that are either the 4 curves or 4 and 8 long straight sections. The deck is ¾ A/C plywood that is also screwed and glued to the frames. With all this screwing and gluing of better to really good plywood I sort of have a time believing it could move much. It would have to be a very solid unit On top of the deck is ½ Homasote screwed and glued to the deck and painted on the top side. With some of the sections being 8 long and all this heavy wood you can see I was not concerned with frequent transport. On top of the ½ Homasote on the main line tracks is Homabed not glued down. I did not take my own advice and paint the Homabed. If there is some movement that is where it probably would be. But clearly this time it was just true rail expansion. Not much of the track is soldered together - mostly on the curves. This first kink was with SHS flex track. I wonder if the size of the rail has any effect on the expansion. I tried to not go end to end tight on the rails. I guess the rails will show be where I could have left more space!
