Experts refer to them as “ sun kinks,” and they occur when the heat causes the metal to expand sufficiently that the structure of the tracks can't take it, and the rails warp. how climate change could affect transportation infrastructure in the The potential good news, as Climate Central notes, is that sun kinks.
Rail News: MOW rail can bend or warp because of a blistering sun and sweltering temps. If the rail malformations known as a " sun kink" or " track buckle" aren't kinks and buckles by determining the actual rail temperature and identifying rail with rail pullers that can be used to adjust the desired neutral rail temperature.

A Florida jury looked on in open-mouthed astonishment when the defense attorney's pants caught fire - in an arson case. Another way to prevent kinks and buckles is to maintain ballast condition, including the shoulders, says Track Guy Consultants' Zuspan. On the record with Amtrak Chairman Anthony Coscia NEW!

Since the neutral temperature can't be set when rail is laid, "we must set the desired neutral temperature, which is determined by each railroad based on their criteria," says Zuspan, adding that the American Railway Engineering and Maintenance-of-Way Association AREMA provides a formula to compute a desired neutral temperature. Harsco Rail's ZETA-TECH unit provides those types of training services for the maintenance and inspection of continuous-welded rail CWR , says Don Holfeld, the company's director of training and field engineering. ZETA-TECH's two-day CWR training course was prepared in part to meet FRA and FTA requirements, as well as to be in compliance with AREMA requirements, says Holfeld. Without sufficient shoulder ballast or if the ballast is contaminated or muddy, the track structure will be relatively weak, he says. Just as people can suffer sunburn or heat stroke from too much exposure to sunlight and hot temperatures, rail can bend or warp because of a blistering sun and sweltering temps.
Rail can be de-stressed as part of welding operations, as well. Without sufficient shoulder ballast or if the ballast is contaminated or muddy, the track structure will be relatively weak, he says. The device provides "highly accurate data [that] can be transmitted a number of ways, including cellular or radio," says O'Kelly, adding that a MultiSensor can come equipped with an alarm. So, railroads will continue to count on suppliers to provide even more ways to prevent buckles and bends on all types of track. So, lubricating rail joints to ensure they don't become "frozen" with rust and can offer some slight movement is one of the best.
