A Trestle
Railroad tracks that were built in the early 1900s were constructed from steel. The steel was used to replace rail tracks and railway cars that were built from iron prior to the early 1900s.
Twenty wheels connectd to the tracks.
The first train tracks built across Kansas from the north to south was the Atchison, Topeka, and Santa Fe.
The tank tracks allows the very heavy tank to move over uneven and soft ground. The tracks spreads the weight of the tank over a longer distance. Ground that wheeled vehicles would soon become bogged down and unable to move forward.
They're called Tracks
The tracks have a larger coefficient of linear expansion than the ground beneath.
