WebLateral thermal buckling is a common cause of derailments in continuously welded rail ( CWR) tracks. Since CWR tracks are constrained against the motion along the direction of travel, extreme temperature changes can induce compressive stresses in the rails that can lead to track buckling.
WebJan 29, 2009 · As far as buckling goes, you're on the right track (pun intended). Expansion, contraction and compression are the three major factors that keep me employed as a railroad worker. In high temperatures, we'll get "kinks" in the track that (I have seen) throw the tracks out of alignment up to 3 feet within a 50-foot distance.
