[quote]QUOTE: Originally posted by Don Gibson [quote]QUOTE: Originally posted by grayfox1119 Is the bowing caused by all the rail joiners being soldered, or is it due to the sub base expanding with humidity?

You might get some heat if you have few feeders and a big current draw through the track, but I think the impact of arcing is going to be minimal. I suspect some other cause. But it doesn't really matter, the point to be taken away is that in most, if not all cases, you have to allow for a bit of movement, whatever the cause.
