" Speed reductions are based on the rail temperature, not the ambient (air) temperature, " Amtrak's statement read. " That data ensures we're only issuing heat restrictions when necessary."

“降速是基于铁路温度，而不是环境（空气）温度，” 美国铁路公司的声明写道。“这些数据确保我们只在必要时发布高温限制。”

我真的相信， 一旦我们越过这个临界点，而且我确实相信我们现在正在这样做， 正如我所说的，那么我认为我们将找到很多方法来加速减排。
