Rails installed last week can do that too. CWR is the rage these days, longer sections, more stress over longer distances and grade, it does catch up just as sun kinks do when it gets hot. The longer you make your sections without adequate compensation for "expand and contract" with temps, the more likely steel will break even if it was done right in the first place.CWR has its advantages, mostly cost. But it has its downsides too. New costs. |
