The document discusses the harsh conditions of railroad tracks, which must withstand heavy loads moving back and forth across them at all hours. Tracks experience weathering and damage from carrying critical resources like coal, oil, and gasoline in large volumes. The toughness of railroad tracks allows them to withstand this difficult "life on the track."

4. Life of the track
 Weathered, battered, and beaten. Hundreds of tons
speeding across. Back and forth at all times of the day.
Carrying items that are in dire need such as coal, oil, or
gasoline. Life on the track is hard and rough. I guess
that’s why they make the tracks so tough!
