Thanks for the info, tetters. I sure would like to see those photos if you dig them up.
As for different batches of rail having different expansion properties, I think the difference would be close to nil. There isn't much difference in the expansion rates of variouos types of brass alloys. The difference is in the 10 millionths of an inch if I remember the expansion chart correctly.
This track buckling has to be a combination of the wood benchwork shrinking due to drying out, and the expansion of the track due to the heat. I'm not worried a bit about my layout cosnidering its past performance in climate extremes, and now it has a comfy home in the layout building.
