Since it appeared that there was a rail kink that caused by high heat, how can high heat in Maryland be compared to the rails in the desert Southwest? When I travel on Interstate 8 between Yuma and Gila Bend, AZ, and on I-10 between Casa Grande and Tucson, AZ, the railroad parallels the highway. In the summer, the temperatures are hotter there than Maryland. Most of the time it can get as high as 115-120 degrees in the low desert. Sometimes, it can go higher than that. I realize that the rails in the desert southwest are or maybe the same as everywhere else, but are they tied down differently than the rails in Maryland, especially where CSX operates the rails? I don't travel those highways in the summer, though. Only in the winter.
