Hot spots are identified based on the average exposed temperature. Rail segments are color-coded based on average land surface temperatures, with darker tones indicating higher thermal exposure. The map highlights areas of high heat susceptibility, particularly around major hubs such as Chicago, St. Louis, and the Northeast Corridor. Insets provide greater detail on selected high-density regions.
