Bill,
It's probably because you wood underneath the track shrunk due to loss of moisture. Wood changes dimensions more across the grain with moisture content than with the grain. What it the relative humidity in the basement now versus the summer? With this cold weather the past week, in my basement is down to 25%, which is what it also is in the house and very low. Last week, when it was warmer, the humidity was in the 30's%. I do run a dehumidifier, but it doesn't much in the winter. I'm allergic to mold so I don't usually add moisture, with the exception of cases containing musical instruments made of wood.

Maybe I did not leave enough gaps when I laid the track. So on both mainlines I removed short sections and gave them a trim. Here all along I though hot = expansion and cool = contraction. It is probably mid 60s in my basement now. It might get a little hotter in the summer but still. Maybe someone has an explanation as to why my track grew in multiple places in the middle of winter! Thank You, Bill Lane
